Stalker Clear Sky	Source: GSC

Stalker: Clear Sky is a prequel to Stalker: Shadow of Chernobyl. The player assumes the role of Scar, a veteran Stalker mercenary who is rescued by Clear Sky, a faction looking to explore the ruins of the Chernobyl power plant and solve the mystery at the heart of the Zone. The Sun Shafts test is part of Stalker's benchmarking suite, which uses DirectX 10 graphics capabilities and can stress even the fastest videocards.

Crysis 1.2	Source: Electronic Arts

Crysis is a science fiction first-person shooter developed by Crytek. Crysis uses Microsoft's new API, DirectX 10 for graphics rendering, and includes the new engine—the CryEngine 2—that is the successor to Far Cry's CryEngine. CryEngine 2 is among the first engines to use the DirectX 10 framework of Windows Vista, but can also run using DirectX 9, both on Vista and Windows XP.

Crysis has always worked well with NVIDIA's older videocards (except when AA is enabled) but that's still not enough to make the game playable at anything but 1280x1024 resolution with the ASUS EN9600GT DI/512MD3/A videocard.
