Hi guys, I did a minor performance tweak to the Sprite class's _update_position method a while ago, and thought I'd share it. You can see it in my "sprite_optimization" branch here: https://bitbucket.org/treehousegames/pyglet/src/124e1fe4c0016cf9effcf3c1706c0124aa99712e/pyglet/sprite.py?at=sprite_optimization&fileviewer=file-view-default Basically it's just cutting out the temporary vertex list creation, and removing a if/else few checks. I've tested it with a few thousand sprites, and this nets a few extra FPS. Not a major improvement, but it's also a bit easier to read the method in my opinion.
The only drawback to this tweak is that Sprite vertex_lists are always created as float arrays, even if sprite subpixel is not used. This is to avoid one of the if/else checks in the method. It is my understanding that on modern GPUs (last 10 years), floats are used internally anyway, so this shouldn't hurt performance any. Would this make sense to try to get merged in, or is there some glaring issue that I'm missing? -- You received this message because you are subscribed to the Google Groups "pyglet-users" group.
