I run all my games at 1920x1200 I also suspected that it could be a CPU bottleneck issue, but Unreal 3 engine games are typically very GPU dependant, and I'm not having performance issues with any other games. After browsing some other forums, it seems that I'm not the only one having problems with The Bureau. I'm starting to think that it's just a poorly optimized title. *Edit* - Yep, it's definitely a poorly optimized game. Many people with faster systems than mine are struggling to get decent framerates. Luckily, it turns out that one option in particular, "Screen Space Reflection", is responsible for really killing the fps. After disabling that, I'm able to apply 4x SGSSAA without a problem.
