I get totally unplayable FPS at 1900x1200 (native) regardless of the rest of the settings. This is amplified at the beginning of the office level (with the rain). I've followed most of the advice I could find in this forum (along with not being a computer novice to begin with), but I cannot resolve the issue. Here's more system info and what I have done:
Windows 7x64 ultimate
AMD Phenom x3 Black @ Stock
Radeon HD5850 1gb 9.12
8gb RAM
SB X-Fi Plat PCI
300GB + HD space free on a 1TB Caviar Black
KF = 0% fragmentation, overall < 5% (Diskeeper 2010)
Microsoft Security Essentials (Whitelisted steam directory)
Cache set to 256mb; I load the level in just a few seconds
Overheating is not a problem (verified HWmon)
At 640x480 windowed, the game has perfect FPS at low settings, but it is nowhere near where it should be on highest settings (I see a stutter). Mouse lag settings have no effect. For perspective, I play crysis at 1900x1200 on gamer settings at ~30fps. I was also able to run the KF demo a few weeks back (free weekend) at max settings without any trouble at all. This was on catalyst 9.10 (I think) and I'm unwilling to roll back unless a dev verifies that's the specific issue.
Please help. I can provide more info if necessary.
