C# XNA Make rendered screen a texture2d
- by redcodefinal
I am working on a cool little city generator which makes cities in the isometric perspective. However, a problem arose where if the grid size was over a certain limit it would have awful lag. I found the main problem to be in the draw method. So I took the precautionary step of rendering only items that were onscreen. This fixed the lag but, not by much.
The idea I have is to render the frame once and take a snapshot. Then, display that as a texture2d on screen. This way I don't have to render 1,000,000 objects every frame since they don't change anyways.
TL;DR - I want to
Take a snapshot of an already rendered frame
Turn it into a Texture2D
Render that to the screen instead of all the objects.
Any help appreciated.
