Hi!
i not understand why my GFX.WaitForPresent take a lot of memory, gpu usage is good, i miss something?
I’m not sure where you got the idea that it takes memory. It says that WaitForPresent is taking 14.71 milliseconds of the frame time. Since the gpu is so underloaded my guess is you have Vsync enabled and the engine waits for the next opportunity to push the frame. If you have Vsync on can you turn it off and check the profiler again?
