Riofl, check your pending credits. Mine have gone up almost 8000 the last day or so and my RAC has taken a dive.

riofl:
ahh forgot about them. ok im writing current down and will put the script back into operation till sometime tomorrow

CUDA workunits under the 2.6.31 kernel take between 2-4 times longer than they should. I may add, that while these units are running, compositing effects (such as wobbly windows and other eye candy) are extremely stuttery. This wasn't the case with the 2.6.27 kernel.

I'm running a phenom 955 CPU, GTX 275 GPU.

I'm beginning to suspect that someone left some debug options enabled in your kernel. What's the output of :

--- Code: ---zgrep DEBUG /proc/config.gz
--- End code ---

lordvader:
Interesting ...
Here's the output.

interesting... doesnt look like i will have the large increase you did but my rac went down by about 100 points but my pending went up by almost 300 points.. wonder why pending increases when running more aggressively?
