Cryostasis : Sleep of Reason Demo
Developed by Action Forms and released in April 09, this is one of the first games to make extensive use of nvidia Physx technology. The graphics engine is AtmosFear 2.0 and shows off some amazing DX10 affects. The graphics seem to capture the feeling of being stranded and cold like few other engines can. An official tech demo for the game engine was recently released to demonstrate the various bells and whistles of the graphics engine and also the new PhysX technology affects. For this article, I have not implemented any Physx analysis. If you are interested, though, Benchmarkextreme featured an article about Physx scaling in Cryostasis.
Average FPS
Both the multi GPU solutions yield heavy gains, right up to around 4.0 GHZ.
Minimum FPS
There are two major points to note here. With a single card there wasn't a huge difference in average FPS at 1680 X 1050, but the minimum FPS show a significant FPS. Your gameplay experience will definitely improve if you overclock your CPU to around 3.6 GHZ, even if you are using a single GTX 285. Another thing to note is how TRI SLI is performing worse that Dual SLI. Yes, this is not uncommon when playing at low resolutions. Tri Sli is meant for high resolution gaming and at lower resolutions you are negating its benefit by using a slow CPU.
Average SLI Scaling
SLI Scaling isn't all that great at these resolutions. Far from ideal.
