This post can be found on steam's Killing Floor forums as well. I just thought that this would be a more specific and helpful subforum to post this in.
I recently upgraded from a Sapphire Radeon HD 4870 (512mb) to an ASUS EAH5870 (Radeon HD 5870, 1gb) and tried to play Killing Floor on it. However, to my disappointment, I have found that Killing Floor tends to lag quite a bit when in-game. It does fine on menus (server lobby, options, etc), but that's it. Here's my system specs.
Processor: Intel Core 2 Duo E8600 Wolfdale
Memory: OCZ Reaper HPC 4GB (2 x 2GB)
Hard Drive: 2x500GB WD Caviar SE16
Video Card: ASUS EAH5870
Keyboard: Logitech G15 Revision 2 USB
Mouse: Razer Diamondback 3G USB
Operating System: Windows Vista Business x64
Motherboard: ASUS P5K Pro
PSU: Gigabyte ODIN PRO(GE-MK20A-D1) 1200W
The game ran just fine on my 4870, all my drivers are up to date, this is the _only_ game this has happened in so far, and yes my vista business license is legitimate.
I'd like to thank anyone who helps me out on this in advance.
Edit: So after some heavy testing I've found that it's the Anti-Aliasing that's giving me serious problems. Anything above 2x and my framerate goes to 10-15 )= Any ideas why?
