Honestly, I have no idea what Copy To Texture was set to before I killed the proprietary driver. I could never see a difference turning it on before. But, trying to get rid of the driver lost OpenGL until I fixed it, and that made Compiz turn off half a dozen plugins. So - who knows how things worked before.
I have no problem leaving it on. I think its slower to have on if you are low on RAM maybe - and I have 8GB - 7.2GB after the on-board video (its a laptop) steals some, or maybe its a software workaround for texture-size limitations? I dunno. Of course, the next guy may get totally different performance with these settings :) It may not be as fast as the proprietary drivers, but its close enough.
