CSS has a real "chunnky" feel to it at 1920 x 1200 - kinda weird - all the writing is mahoosive. But it seems I fare better at 1920 x 1200 than 1680 x 1050 so me likes it It does run at over 100FPS constant tho
Quake needs to be turned down to 2x AA Ultra Quality (with the Dual Core patch on as well) to run smooth but that stays at a constant 60FPS at the highest res so thats ok.
COD 2 can be run at 1920 x 1200 @ 4x AA (all highest details) and keeps just above 30FPS which is ok as its aint as fast paces as Q4, but has more going on on screen.
F.E.A.R can be played at 1920 x 1200 at 2x AA and looks nice but I had to get a higher OC on the video card to do that
Anyhoo - gaming at that res looks really awesome and although takes a bit of geting used to: its pretty nice
