Thanks! Polling is already at 1000 and didn't consider frame rate. I'll check that and make sure vsync is not on.

Wondering if anyone has some updated information regarding binding the mousewheel to "use". I've edited the INPUT.XML file (don't seem to have the .config file anymore), and it works, but it is really slow when spamming. I've tried adjusting my mouse settings, polling rate, etc, but to no avail. Right now, actually spamming E is faster. Did I miss something in the xml? Thanks!
