Doom 3 40% ATI performance increase by Shane L at 15:48

For those of you on the ATI cards there is a little tweak knocking about that allegedly gives a 40% performance increase..

Extract so that the shader file goes under doom3\base\glprogs. This replaces a dependent texture read with equivalent math, which runs better on ATI cards, but seems to run slower on NV boards, so only apply this if you got an ATI card.

	I've seen loads of test results. no-one got over 15%. Most between 3-4%, some no speed increase at all.

	From all the "performance increase" tips and stuff I've read so far, someone will post one and say "I gots 25% incarease lol lol!!!" and then everyone else says "Well I did it and got 1fps increase". I read about this particular one from an ATI developer on a webboard. Nearly everyone on the board shot it down as making very very little difference except on (I think) a 9800Pro.

Why not register and have your say?
