Was board and decided to download the demo for the benchmark. Kind of interesting.
I ran once with my CPU at stock (a q6600 @ 2.4)
View distance at stock 1600 I think
High settings
Texture, Video mem, Shadow detail, post processing
normal settings
Anisotropic and Antaliasing, Terrain, Objects
FPS score was 21
So I rebooted and overclocked the CPU up to 3.0 or so.
Same settings as above gave me FPS=23
I upped the view distance to 3000, and the FPS=21
I upped the Objects and Terrain to High, and FPS=19
This is with 4 gigs of 1066 RAM and an 8800GTS 640mb gfx. card.
I tried to overclock the 8800, but Rivatuner says the drivers aren't recognized (they just came out like last week)
And the interesting thing is the CPU wasn't really straining in any of the tests.
I run a 2nd monitor so I can watch my CPU and RAM all the time, so here is a screenshot to show what it looked like pretty much the whole benchmark run.
This is just the 2nd monitor, the main monitor has the game running.
