In error reports from some I have quite often seen following behaviour: IDirect3DVertexBuffer9::Lock fails, returned error code is D3DERR_NOTAVAILABLE.

Once this happens, quite frequently (but not always) it is followed by CreateTexture or CreateVertexBuffer failing with error D3DERR_OUTOFVIDEOMEMORY.

What are possible reasons for vertex buffer lock failure? Could virtual memory address space exhausted, or what?

Things I've checked so far: D3DRS_ZENABLE, set to TRUE D3DRS_ZWRITEENABLE, set to TRUE D3DRS_ZFUNC, set to D3DCMP_LESSEQUAL The depth buffer is definitely… >>> More

Let's say in a deferred renderer when building your G-Buffer you're going to render texture color, normals, depth and whatever else to your multiple render targets at once. Now if you want to have a gamma-correct rendering pipeline and you use regular sRGB textures as well as rendertargets, you'll… >>> More
