This website's purpose is to categorize your options to turn off filtering. This includes texture filtering (mipmapping, linear, antialias, etc), mouse filtering (smoothing/acceleration), even model filtering and other miscellaneous things including various useful commands.
I don't think it is ALWAYS an improvement, this is a somewhat comprehensive guide and nothing more, take what you like from it. If I know a solution I will list it with the others regardless of my own preference so be warned.
All pages share the same example thumbnail, but not every page has an actual picture for that game just yet.
This website's source is based off the famous bMouse website by SwissCM.
