F.E.A.R
Sierra; F.E.A.R w/ v1.0.8 patch:
F.E.A.R. (First Encounter Assault and Recon) is a first-person close-quarters combat game for the PC. The story begins when a paramilitary force infiltrates a multi-billion dollar aerospace compound, and the government responds by sending in Special Forces. The group loses contact with the government when an eerie signal interrupts radio communications--and when that interference subsides moments later, the team has been destroyed. That's where you come in. As part of a classified strike team created to deal with threats no one else can handle, your mission is simple: eliminate the intruders at any cost, determine the origin of the signal, and contain the potential crisis before it gets out of control.
F.E.A.R. is a pretty recent game title that many people are still playing today. At 1024x768 with 4xAA/16xAF we found a 22 frame per second difference with the AMD Athlon 64 5600+ processor leading the Intel Core 2 Duo E6300.
At the higher resolution of 1600x1200 there was only a 2 frame per second difference shown on the benchmark.
