I really had no idea so many of them did that picmip shit.  It's depressing but at the same time amusing.  They won't give up their crutches even though they claim there's no advantage they gain from them.  I played around with the LODbias (picmip) crap back when I was running my Pentium D.  It didn't give me any more FPS no matter what I did.  It didn't make anything more playable and it didn't reduce my game's crashing.  The only thing it does is make it harder or maybe even impossible for you to lose sight of a player against a background... and this is how we are easily picked off by someone all the way across a dark map consistantly.

The only thing we have close to an anti cheat or anti tweak is the Xray and they won't go for that and it looks like FN won't push it.
