Longtime lurker who just registered here, having trouble with resolutions, and some surprise at the lack of performance on my system. My system:
AMD X2 4200+
2 7800 GT's in SLI Mode (just updated driver)
2gb RAM
Dell 20" widescreen (16:10) with native res of 1680 x 1050
Maybe I'm missing something, but I'm unable to play at the proper aspect ratio nor native resolution of my monitor. The highest res offered is 1280 something or other, and the only aspect ratio's are 4:3, 5:4, and 16:9 (which is probably close enough I guess), but running in a lower, non-native res it just looks awful on my screen. GR1 gave me no problems on my widescreen, so I'm hoping I'm missing something here.
Also, I thought my system would handle this at full res with medium settings like a knife through hot butter. It's definitely not. I'll need to play more with settings before I come to any big conclusions, but this game definitely seems to demand A LOT.
On the plus side, gameplay is AWESOME!!!!!!!!!!
