What I'm seeing is similar. My single card works at 90% -100% with good frame rates (45 -60 fps) at high detail and slight micro stutters at low altitude over landscape. Temperature runs quite warm (60 - 70 C) with fan running at high speed (noisy).
With beta 285.27 driver and Rick's settings in SLI the two cards are running in near parallel at 45% - 65% (higher percentage over land at low altitude) and temps are a little cooler (50 - 60 C) with fans running at lower speed (quieter). Frame rates seem the same as the single card with slight stuttering as well at low altitude over land.
I'm going to remain in SLI mode since there seems to be less operational wear & tear on the cards. Also there may be greater potential to handle greater graphical workloads such as Effects (explosions, clouds, instrument panels), but further work (well, play - actually
) required here to determine that.
My 2.67 CPU is likely a bottleneck for SLI, and possibly 1C will come out with an optimized SLI profile to increase SLI performance.
Nice work, Rick!
