    ok i have a weird problem it's that when i start up F@H gpu2 my ati hd2600xt reports itself as only having 80 unified shaders but when F@H isn't running it reports 120 unified shaders err ??WTF?? why is it doin that:bugeye:

    Because F@H isn't capable of using all of ATI's shaders....least that's my theory....could be wrong.

    Well i found some tweeks one can set in windows registry to enable F@H to use the gfx card better, i got about 500ppd extra from them, + it lowered my CPU usage by a few %. Will post the links when i get home. They are working on a new client, one can only hope it will use the ATI cards to their full potential.

    Ok it's not really registry tweeks, just system variables.

    If you right click on my computer > advanced > environment variables > system variables > new
    then add the following:
    CAL_NO_FLUSH=1
    BROOK_YIELD=2
    FLUSH_INTERVAL=128
    CAL_PRE_FLUSH=1

    The flush_interval can be set higher or lower depending on you gpu. This has lowered my cpu usage while running the gpu client, also gave me a extra boost in ppd. My FI is set to 256 and it work perfect on my setup. Sorry if this have been posted before.

    Here is the definitions of the system variables:

    Also the link to the form where i collected this info:

    If they would switch to OpenCL, performance would improve as a result. Instead, they will probably stick with CUDA for nV and Stream for ATI.

    Where do you see this info?

    I heard that they were working on an OpenCL version of Folding@Home...

    No offense...but as with everything else, I'll believe it when I see it. Software developers rarely like to deviate from proven software architectures.

    @ Deltatux i use everest v5.30

    @ sykozis apparently the new GPU3 core thats comming up early 2010 will use opencl so that other video cards like intel gma and S3/via chrome will also be able to fold aswell but your right i'll believe it too when i see it

    @ deltatux part 2 look at the blue highlighted txt
