F.E.A.R. Retail Version Benchmarking Issue:
Be aware that enabling soft shadows and antialiasing at the same time is allowed in the F.E.A.R. application control panel, but soft shadows will not work when antialiasing is also enabled. This information is documented in the F.E.A.R retail version release notes.
Here is an excerpt from the F.E.A.R. Release Notes:
"The Soft Shadows option will have no effect if the Full-Screen Anti-Aliasing (FSAA) option is enabled. Also, you may notice odd rendering issues with shadows in the game."
