Again? Didn't they get busted for this a few years back?

If by "a few years back" you mean 14 years ago with the quake/quack thing.

But nobody is saying this is the cheating-style "optimizing" which has been judged as invalid. Both Nvidia and ATI do heavy amounts of game-specific optimizations in drivers and so long as there is no visual difference this is perceived to be fair and valid optimization.

Yep, I posted the quake/quack thing including a link, a date and an "oops my mistake" apologetic comment

Only thing I recall similar to this was Intel's compiler not using SSE instructions intentionally on AMD processors. Or were you thinking of something else GPU related?

Looks like I'm older than I realise - it was back in 2001 http://techreport.com/review/3089/how-ati-drivers-optimize-q...
