Negative Crossfire Scaling - AMD or Developers Fault?

S.T.A.L.K.E.R. · 05-15-2011, 10:18 AM

After the 4th patch I can finally play the game due the audio issues being resolved but I've noticed I am getting ♥♥♥♥ performance.

My computer specs are:
Intel Core i7 950
Gigabyte X58A-UD3R Rev 2.0
12.0GB G.Skill DDR3 1600
2x 6950 CFX (11.5a Hotfix Drivers with latest CAPs)

My Game settings are:
Dispaly Mode: 1920x1200 @ 60Hz
Particle System Quality: High
Shadow Quality: High
Character Shadow Quality: High
Water Detail: High
Anti-Aliasing: Off (I don't like the burryness with this on)
V-Sync: Off (For testing purposes, will probably play with it on once issues are sorted out)
Depth of Field: On
High Detail Textures: On

These settings with Crossfire Enabled: 15-35 FPS

These settings with Crossfire Disabled: 60+ FPS

With Crossfire Enabled and forcing AFR Via Radeon Pro I get 100% Crossfire Scaling (120+ FPS) but a lot of flickering and lighting problems in the game.

Is this something the developers are going to have to patch/fix or is this something AMD is going to have to deal with in their drivers?

Most of the time when dealing with SLI/Crossfire, it is a driver issue. Same with this game. Since you are using RadeonPro, use the fear.exe profile as this is the only one I have found that doesn't have said lighting issues. Hopefully a new CAP will be out with a profile for this game.
