Swapbuffers slow
SpletThis is considered as rendering speed by most gamers and new programmers. FPS is not always the best way to measure performance because it is not linear in the time domain. It is better to measure frame time, which is the inverse of the FPS (conversely, FPS is the inverse of frame time). So if the FPS is 25, the frame time is 1/25 = 0.04 seconds. Splet28. jan. 2016 · After around 200 frames one can see that SwapBuffers starts to block almost like OpenGL switches mode in to a more strict synchronization.
