[quote name='Psybuster']Check his post more carefully, GTX 460 SLI, the 8800GT is just for PhysX. But yes there's something funny going on with Very High settings that just doesn't play nice at the moment, not sure whether it's an NVidia only problem or with the game itself.[/QUOTE]
Probably both. No intent to start a fight, but by most accounts (including the music director of Bioware), the game was a rushjob. Apparently, ATI cards run the game very well so long as you have a high end one. Even super high end cards by nVidia cannot run the game as well because it was optimized heavily for ATI, due partly to ATI marketing for this game AND partly to the fact that the Xbox 360 (the lead platform) has an ATI GPU inside it.
I've been reading the threads on the latest nVidia drivers (270.32, 267.46, 267.26, 267.24/31) and all of them report that the game performs pretty badly on any of them and regardless of hardware. Turning on DX11 is supposed to be TOTALLY great in as far as the graphics go, but nVidia users are all being told by Bioware currently to run it at DX9 because DX11 is just not smooth enough for them. Naturally, Bioware and nVidia are being blamed. I believe a 270-based driver will show up in the next week or so to alleviate the situation, but the one that's floating around currently seems to have only marginal improvements for the game.
In the end, I think Bioware might have to be the one who fixes the performance problems.
