One of the little performance tweaks I've come across for Pyglet involves setting the processor affinity for the running app. The Python interpreter is effectively single-threaded, and so allowing it to run with the default affinity (all cores) can actually harm performance in some cases.
Consequently, setting the affinity of the running process to a single core can sometimes speed it up, because there's less context switching and less cache eviction.. I'm not sure how to accomplish this in Linux or on MacOS, but in Windows, it's easy enough: import ctypes k32 = ctypes.windll.kernel32 k32.SetProcessAffinityMask(k32.GetCurrentProcess(), 1) I'm doing this with a game I'm working on now and it provides a noticeable, if not terribly dramatic, speedup. I also use this in conjunction with bumping the process priority slightly, something I've discussed before: ctypes.windll.kernel32.SetPriorityClass(-1, 0x8000)) -- You received this message because you are subscribed to the Google Groups "pyglet-users" group.
