FEAR	Source: Sierra

FEAR is Sierra's latest first person shooter which relies heavily on DirectX 9 features. With its "Soft Shadows" feature enabled, even the fastest videocards run at a crawl, FEAR is definitely the new benchmark for future FPS games to follow.

One thing is for sure, with Soft Shadows enabled the amount of video memory certainly has a big impact. That is why the 512MB GeForce 7800GTX and Asus EAX1900XTX which also has 512MB completely outperform the other reference videocards.
