If there's one thing PrecacheClasses in Gameinfo doesn't handle, it's PSprites. Would it be possible to add a property that allows specifying weapon sprites for precaching?
In D4D, I introduced some very high quality images for the Crucible blade. But upon bringing the weapon up for the first time, it stutters greatly while the weapon caches. This happens when also swinging and returning to the ready state because they previously weren't ever used.
These also contain hires versions, and I made sure to compress them down as much as possible.
