Benchmark Results: Left 4 Dead 2

by

The original Left 4 Dead is one of Lucid’s supported titles, but there’s apparently enough different with the sequel to mess with X-mode when we manually add it to Hydra’s control panel. In addition to a significant performance hit, we also saw black flashing bars during configuration and game play.

A noticeable speed-up in A-mode lets us know both cards are running, but the scaling here isn’t quite as good as it is in CrossFire mode. N-mode tells a similar tale, with the SLI’d cards outperforming Lucid’s N-mode.

This tech was never really going to work without backing from both ATI and N-Vidia, the architectures are too different to be able to talk coherently without serious interpretation

I recall that Nvidia drivers will not allow you to use their card if it finds that there is a ATi card as well, and only Cracked drivers are availible for such a configuration...

i believe you can use an nvidia card to provide physx support but not to render graphics when there is an ati card present, but only under windows 7

how about nvidia and ati combine themselves and offer only 4 titles:

1> entry level - 100$
2> performance level - 200$
3> gaming level -300$
4> enthusiast level-400$

will be much better i think...

thats a common opinion but its generally crap as without competition theres no innovation(excluding war of course but thats just really intense competition)

ForceWare 181.22 (exactly this version, not older or newer) won't disable Physx when ATI cards are present. This way you can render games on ATI cards WITH Physx support (only in Windows 7 ofcourse).
