I'm getting great scaling ~70-100% in everything I have tried except Crysis / Crysis Warhead, I get ~10-20% negative scaling when crossfire is enabled.
I have tried 11.1a and 11.2 drivers. Going by benchmarks I have seen I should at least see some gain.
The bencharks seem to use the 10.11 beta ~ 10.12a drivers, but I do not want to downgrade.
I swapped out my MB (Gigabyte GA-X58A-UD5) with one that has a space between the cards (MSI X58A-GD45) thinking it was heat related, but there was no change except both cards now run cool.
I did perform a fresh install of Win7 Ultimate 64 bit.
I tried both cards individually and in Crossfire at stock, 6970 bios, Unlocked shaders, and Unlocked shaders + OC the same results each time, the single card was 5 - 10 fps faster than crossfire depending on settings.
System specs
MSI X58A-GD45
i7 950 ~ 3.8 167 bus (turbo ~4ghz) stock voltage on all settings
12 GB @ 1333 cas 7 1T
Could someone verify Crysis / Crysis Warhead performance and what driver version you are using?
Thanks,
