I ran a 45 second benchmark near the very beginning of the 2nd stage, Welcome to the Jungle, right when you step out of the building and see the inside of the dome the first time. I did a 45 second loop around the grassy area from the stairs to the open sunshine and back.
Intel Mini ITX H67
First number is Average, second is minimum.
All settings were run on 1080p, cept for a couple with with GTS 450.
I did 3 runs each on High, Med, Low, with FXAA turned on, AF 16, NO Motion Blur, Lens Flare on, Textures set Very High.
Turning the textures down netted me about 1 FPS per step. The difference between FXAA on and off was only 1 FPS for each card.
Well...the fact is that these scores are not relevant because this game is designed for 4 core CPUs... Still if You get 22 minimum on GTX 560Ti with this CPU I guess this game is not that bad as everyone keeps sayin it is in terms of performance.
BTW - why did You decided to combine 670 with i3 CPU? To me it seems ridiculous.
