• Blue Screen Of Death after Graphics Card Update

  - by John Smith

  I recently installed the game watch dogs After installing it i upgraded the drivers on my graphics card AMD Radion R9 200 series via the catalyst software and since then windows has been crashing on an ad-hoc basis even when sitting idle I have recieved two different sets of errors OXOOOOOOO1 and VIDEO_SCHEDULER_INTERNAL_ERROR I am running windows 8.1 with the driver 14.4 from AMD My PC shouldnt really be having this problem as it is pretty high spec due to my work Any help would be greatly appreciated as it is driving me up the walls a bit [UPDATE 08-06-2014] I have been looking around online and have crashed the PC a few times now trying to recreate the bug I have looked into the event history viewer and gotten the following errors amdacpusrsvc acpusrsvc: IOCTL_ACPKSD_KSD_TO_USR_SVC_SET_FB_APERTURES: FAILED acpusrsvc: GfxMemServiceInitialize: FAILED amdacpusrsvc acpusrsvc: IOCTL_ACPKSD_KSD_TO_USR_SVC_SET_FB_APERTURES: FAILED amdacpusrsvc acpusrsvc: GfxMemServiceInitialize: FAILED I took some advice from the AMD forums to re-install the old drivers to see if they would work. I uninstalled the old ones first and installed directly from the CD I got the warnings below but the driver installed "successfully" The Warnings are amdacpusrsvc acpusrsvc: ConfigureFrameBufferMemory: FAILED. Hopefully this will spark something off for someone Thanks John

• ATI radeon hd 5450 Graphics Card Issues

  - by RGM-79FP GM Striker

  I have an Old Dell Optiplex 755 SFF with an Intel Core 2 Processor (windows 7). Now This can hold a PCI-E x16 port. Now I got an ATI Radeon HD 5450 low profile. I plugged and played and it fits without a hitch, the software installed too! , now for the graphics well... It doesn't really work at all as it seems to freeze at the moment that it loads on the windows logo. It loads into safe mode so I'm not really sure what the problem is. Any ideas, I read the dell forums and they should be somewhat compatible... with the specs so I'm at a loss here. and I am a novice here. Ideas? Edit I have tried to reset the cmos,no luck there. I have tried to move the ram as well. nothing big happened.

• Dual-headed graphics card choice: DVI & VGA with 512MB _or_ DVI & DVI with 256MB

  - by TimH

  Which would you choose? Some more detail: I can choose between: A dual-headed card with both heads DVI but only 256MB of memory A dual-headed card with one VGA and one DVI, with 512MB of memory. Both monitors are 1600x1200 I'll be doing mostly business app development on the computer. No gameplay or advanced graphics work. It's running Win7 and is a quad-core i5. I'm thinking of going with 256MB one, just so both displays are DVI and I don't have to shift between sharp & blurry when I look from one screen to the other. But I'm not sure if the additional RAM would be a huge boon for some reason (Win7 GPU acceleration, for example? But with a quad-core, who cares?).

• Graphics card failure, anything I could try...

  - by ILMV

  My gaming PC has decided to die, it's not the first time but usually a quick ATX reset brings it back to life. Today it didn't. I disconnect all unessasary devices so I've only got the case button / LED cables, GPU, CPU, RAM and power connected, the computer still didn't turn on. I've not got a speaker on my motherboard so found a spare one I have for testing and when the machine starts up I get one long beep and two short beeps from my Award BIOS, which apparently means a video card error. I change it with the GPU from another machine and all works well. Q: So I have a faulty graphics card (an nVidia 8800GT OC), is there anything I can try to resurect it?

• Laptop monitor goes black under intense graphics

  - by drahcir

  I have a dell inspiron 1520 with a nvidia GeForce 8600M GT video card. I have Windows 7 professional as an operating system. Yesterday when I was using it the screen started to somewhat flicker then go completely black. I restarted it and in the boot screen everything seems fine, when I entered the login screen it became flickery again, and when I logged in, when a couple of windows popped up it went black again. I hooked it up to a tft monitor and the monitor works fine, and did some more tests that confirmed that under higher graphics causes the laptop monitor to go black. Is there a reason why this is happening?

• Graphics Card Compatability

  - by Aaron

  I am a first time builder and while I have the basic understanding of how to put a computer together, one final thing eludes me. What are the requirements for instaling 2 or more graphics cards on a computer? Example: EVGA 015-P3-1589-AR GeForce GTX 580 (Fermi) FTW Hydro Copper 2 1536MB 384-bit GDDR5 PCI Express 2.0 x16 HDCP Ready SLI Support Video Card ECS NGTX580-1536PI-F GeForce GTX 580 (Fermi) 1536MB 384-bit GDDR5 PCI Express 2.0 x16 HDCP Ready SLI Support Video Card I am not planning on buying either of these cards in the near future. I simply am using them as an example because of the number of differences. As I understand it these two cards will work together (given the proper motherboard) because the only thing that matters is that they are both GeForce GTX 580. Is my assumption correct? If not, why?

• Problem with fitting graphics card

  - by Gary Robinson

  I have recently purchased a new radeon hd5670 graphics card. The problem I have is that it is what I might call a double height card. So the end where you fix the card to the case is twice the size of the card it is replacing. But this means that it is blocked by the rear of the network card. The only way I can see it to cut that part of the fixture part out then I won't have a problem. But has anyone any suggestions what I could use? To be clear it is not the actual card it is the fixture part which is 90 degress to the card that is causing the problem. Unless someone knows of another solution - some kind of pci-e extender that I could use as I could easily

• Latest XP Drivers for Intel Integrated Graphics

  - by John

  On the Intel site I'm struggling to find what the latest driver version is for certain chipsets. From a system info tool I have several PCs (laptops) with the following reported graphics: Mobile Intel(R) 4 Series Express Chipset Family Intel(R) Q35 Express Chipset Family Intel(R) Q45/Q43 Express Chipset All use the same driver igxprd32.dll at version 6.14.0010.4xxx (last 3 digits vary). All PCs are XP 32 bit. I am not certain but I think these are all using the same basic chipset. More than likely the drivers were never updated so I wondered what version might be relevant. Any help on tracking down the latest driver version (I just need the number, so I can see how out of date they are) and figuring out which chips these cards are would be great.

• Ultrabook graphics card for gaming

  - by Francisc

  I want to get a Windows 8 "ultrabook" that I can also use for gaming. Most seem to have Intel HD Graphics 4000 (integrated) or NVIDIA GeForce GT 620M (dedicated). From experience, are they any good? Things I enjoy playing are Call of Duty, Fifa and Skyrim for example. I'm looking for a device that will work on the next generation of those games as well, so it shouldn't just barely work on the current versions that exist now. So, would those two cards suffice? Any advice is much appreciated. Thank you.

• Remote Graphics Diagnostics with Windows RT 8.1 and Visual Studio 2013

  - by Michael B. McLaughlin

  Originally posted on: http://geekswithblogs.net/mikebmcl/archive/2013/11/12/remote-graphics-diagnostics-with-windows-rt-8.1-and-visual-studio.aspxThis blog post is a brief follow up to my What’s New in Graphics and Game Development in Visual Studio 2013 post on the MVP Award blog. While writing that post I was testing out various features to try to make sure everything worked as expected. I had some trouble getting Remote Graphics Diagnostics (a/k/a remote graphics debugging) working on my first generation Surface RT (upgraded to Windows RT 8.1). It was more strange since I could use remote debugging when doing CPU debugging; it was just graphics debugging that was causing trouble. After some discussions with the great folks who work on the graphics tools in Visual Studio, they were able to repro the problem and recommend a solution. My Surface RT needed the ARM Kits policy installed on it. Once I followed the instructions on the previous link, I could successfully use Remote Graphics Diagnostics on my Surface RT. Please note that this requires Windows RT 8.1 RTM (i.e. not Preview) and that Remote Graphics Diagnostics on ARM only works when you are using Visual Studio 2013 as it is a new feature (it should work just fine using the Express for Windows version). Also, when I installed the ARM Kits policy I needed to do two things to get it to work properly. First, when following the “How to install the Kits policy” instructions, I needed to copy the SecureBoot folder into Program Files on my Surface RT (specifically, I copied the SecureBoot folder to “C:\Program Files\Windows Kits\8.1\bin\arm\” on my Surface RT, creating any necessary directories). It may work if it’s in any system folder; I didn’t test any others after I got it working. I had initially put it in my Downloads folder and tried installing it from there. When the machine restarted it displayed a worrisome error message. I repeatedly pressed the button that would allow me to retry and eventually the machine rebooted and managed to recover itself to its previous state. Second, I needed to install it as an Administrator. The instructions say that this might be necessary. For me it was. This is a Remote Graphics Diagnostics is a great new feature in Visual Studio 2013 so I definitely encourage all of you to check it out!

• Best direction for displaying game graphics in C# App

  - by Mike Webb

  I am making a small game as sort of a test project, nothing major. I just started and am working on the graphics piece, but I'm not sure the best way to draw the graphics to the screen. It is going to be sort of like the old Zelda, so pretty simple using bitmaps and such. I started thinking that I could just paint to a Picture Box control using Drawing.Graphics with the Handle from the control, but this seems cumbersome. I'm also not sure if I can use double buffering with this method either. I looked at XNA, but for now I wanted to use a simple method to display everything. So, my question. Using the current C# windows controls and framework, what is the best approach to displaying game graphics (i.e. Picture Box, build a custom control, etc.)

• Icons/graphics for your applications

  - by rein

  I need to source some graphics/icons for my application I'm writing (Windows WinForms). I need graphics for toolbar buttons, icons for form headers and graphics for wizard dialog boxes. As a last resort I'm willing to create them myself - a move that might make them (and my whole application) look amazingly bad. What are some good sources (free or not) where I can get these kinds of programmer icons? I'd like the icons to be at least 32x32 256 color.

• ActionScript Aligning Graphics Line Style Stroke?

  - by TheDarkIn1978

  is it possible to align the stroke of a graphic with actionscript? for example, the following code creates a black rounded rect with a grey stroke that is automatically centre aligned. var t:Sprite = new Sprite(); t.graphics.lineStyle(5, 0x555555); t.graphics.beginFill(0, 1); t.graphics.drawRoundRect(25, 25, 200, 75, 25, 25); t.graphics.endFill(); the lineStyle function doesn't seem to offer any built-in functionality for aligning the stroke. in Adobe Illustrator, you can align a stroke to be either centre (default), inside or outside.

• initializing a vector of custom class in c++

  - by Flamewires

  Hey basically Im trying to store a "solution" and create a vector of these. The problem I'm having is with initialization. Heres my class for reference class Solution { private: // boost::thread m_Thread; int itt_found; int dim; pfn_fitness f; double value; std::vector<double> x; public: Solution(size_t size, int funcNo) : itt_found(0), x(size, 0.0), value(0.0), dim(30), f(Eval_Functions[funcNo]) { for (int i = 1; i < (int) size; i++) { x[i] = ((double)rand()/((double)RAND_MAX))*maxs[funcNo]; } } Solution() : itt_found(0), x(31, 0.0), value(0.0), dim(30), f(Eval_Functions[1]) { for (int i = 1; i < 31; i++) { x[i] = ((double)rand()/((double)RAND_MAX))*maxs[1]; } } Solution operator= (Solution S) { x = S.GetX(); itt_found = S.GetIttFound(); dim = S.GetDim(); f = S.GetFunc(); value = S.GetValue(); return *this; } void start() { value = f (dim, x); } /* plus additional getter/setter methods*/ } Solution S(30, 1) or Solution(2, 5) work and initalizes everything, but I need X of these solution objects. std::vector<Solution> Parents(X) will create X solutions with the default constructor and i want to construct using the (int, int) constructor. Is there any easy(one liner?) way to do this? Or would i have to do something like: size_t numparents = 10; vector<Solution> Parents; Parents.reserve(numparents); for (int i = 0; i<(int)numparents; i++) { Solution S(31, 0); Parents.push_back(S); }

• Initializing a C++ vector to random values... fast

  - by Flamewires

  Hey, id like to make this as fast as possible because it gets called A LOT in a program i'm writing, so is there any faster way to initialize a C++ vector to random values than: double range;//set to the range of a particular function i want to evaluate. std::vector<double> x(30, 0.0); for (int i=0;i<x.size();i++) { x.at(i) = (rand()/(double)RAND_MAX)*range; } EDIT:Fixed x's initializer.

• C++ Vector vs Array (Time)

  - by vsha041

  I have got here two programs with me, both are doing exactly the same task. They are just setting an boolean array / vector to the value true. The program using vector takes 27 seconds to run whereas the program involving array with 5 times greater size takes less than 1 s. I would like to know the exact reason as to why there is such a major difference ? Are vectors really that inefficient ? Program using vectors #include <iostream> #include <vector> #include <ctime> using namespace std; int main(){ const int size = 2000; time_t start, end; time(&start); vector<bool> v(size); for(int i = 0; i < size; i++){ for(int j = 0; j < size; j++){ v[i] = true; } } time(&end); cout<<difftime(end, start)<<" seconds."<<endl; } Runtime - 27 seconds Program using Array #include <iostream> #include <ctime> using namespace std; int main(){ const int size = 10000; // 5 times more size time_t start, end; time(&start); bool v[size]; for(int i = 0; i < size; i++){ for(int j = 0; j < size; j++){ v[i] = true; } } time(&end); cout<<difftime(end, start)<<" seconds."<<endl; } Runtime - < 1 seconds Platform - Visual Studio 2008 OS - Windows Vista 32 bit SP 1 Processor Intel(R) Pentium(R) Dual CPU T2370 @ 1.73GHz Memory (RAM) 1.00 GB Thanks Amare

• Euler rotation of direction vector

  - by Tom Savage

  I have defined an object in 3D space with position, rotation and scale values (all defined as 3D vectors). It also has upwards and forwards direction vectors. When I rotate the object, I need these direction vectors to rotate with it. Assuming my up vector is (0, 1, 0) and my forwards vector is (0, 0, 1) at zero rotation, how might I achieve this?

• variable scope when adding a value to a vector in class constructor

  - by TheFuzz

  I have a level class and a Enemy_control class that is based off an vector that takes in Enemys as values. in my level constructor I have: Enemy tmp( 1200 ); enemys.Add_enemy( tmp ); // this adds tmp to the vector in Enemy_control enemys being a variable of type Enemy_control. My program crashes after these statements complaining about some destructor problem in level and enemy_control and enemy. Any ideas?

• Dual NVidia graphics cards in Ubuntu / xorg.conf mania

  - by John Zwinck

  I have two NVidia graphics cards: Quadro NVS 295 (PCI Express, dual DisplayPort outputs) GeForce FX 5200 (PCI, DVI and VGA outputs) I have three identical monitors, two on DisplayPort and one on DVI. I'm on Ubuntu Hardy (and cannot currently dist-upgrade for separate reasons). I use the "nvidia" driver. What's new is the GeForce card and the third monitor. I currently have the dual DisplayPort monitors working fine. Here are the display-related parts of my xorg.conf: Section "ServerLayout" Identifier "Default Layout" Screen "PCI-Express Screen" 0 0 # adding this makes X fail to start: Screen "PCI Screen" 0 Inputdevice "Generic Keyboard" Inputdevice "Configured Mouse" EndSection Section "Module" Load "glx" # not sure why/if this is needed EndSection Section "Monitor" Identifier "DELL 2408WFP" Option "DPMS" EndSection Section "Device" Identifier "NVIDIA Quadro NVS 295" Driver "nvidia" Option "RenderAccel" "true" Screen 0 BusID "PCI:2:0:0" EndSection Section "Device" Identifier "NVIDIA GeForce FX 5200" Driver "nvidia" Option "RenderAccel" "true" Screen 1 BusID "PCI:6:4:0" EndSection Section "Screen" Identifier "PCI-Express Screen" Device "NVIDIA Quadro NVS 295" Monitor "DELL 2408WFP" Defaultdepth 24 Option "TwinView" "True" Option "UseEdidFreqs" "True" Option "MetaModes" "1920x1200 +0+1200, 1920x1200 +0+0" EndSection Section "Screen" Identifier "PCI Screen" Device "NVIDIA GeForce FX 5200" Monitor "DELL 2408WFP" Defaultdepth 24 Option "TwinView" "True" Option "UseEdidFreqs" "True" Option "MetaModes" "1920x1200 +0+0" EndSection I use nvidia-settings to configure my monitors, and it does not show the second GPU. lspci, though, shows: 02:00.0 VGA compatible controller: nVidia Corporation Unknown device 06fd 06:04.0 VGA compatible controller: nVidia Corporation NV34 [GeForce FX 5200] Which is where I got the BusID settings for the two devices (when I just had one device, I didn't have any BusID listed...and adding the BusID hasn't broken anything). What am I missing? How can I make nvidia-settings show my second GPU so I can then configure its monitor?

• Graphics Artifacts/ Texture Flickering

  - by Cerin

  Hey I been having some problems with artifacts in games. Sometimes textures flicker. Artifacts of various shapes and sizes show up usually after a couple games of dota 2. I built my computer almost exactly one month ago and it has been doing this pretty much from the start except before the artifacts I believe just flashed on screen fast enough to where I couldn't tell what it was but I still noticed. In dota I've seen green triangular artifacts among other things. I've tried running Furmark for a while but even though it pushes the gpu much harder than dota 2, there are still no artifacts. It maxes in furmark at about 60C and running every game I've tried on it at 40C. CPU and system temp don't usually get higher than 40C either. These are my system specs: Gigabyte Z68 Intel Motherboard 16 GB Gskill Ripjaws SDRAM DDR3 Sapphire Radeon HD 7770 GHz edition Intel Core i5-2500k (with built in gpu) Corsair 750 Watt PSU windows 7-64 bit I have the latest drivers for everything. What should I do about this? Try to RMA my graphics card? Are there other things that could be causing this?
