OK as an NVidea GPU user I've just installed the CUDA stuff to give it a try.
I'm running latest drivers/toolkit/Nebula x64 on REaper 3.51 x64 under win 7 x64.
I have changed the opt freq to 15cuda and the cnv to 3800,loaded an Alex b console program and copied this to 4 tracks.Reapers CPU meter is in the red at 128% even though in task manager my cpu is showing 2%.
What is going on here? I thought CUDA was supposed to help.

you should use it ONLY for long tailed programs, so reverbs, equalizers or preamps. Kernel size should be AT LEAST 150 ms, and possibly all kernels should be sized in the same way. If you follow these suggestions you'll experience some serious power saving.
So are you saying that consoles like MBC pro cannot be used? Also there should be a sticky somewhere explaining this and the relevant settings to get CUDA working,and, perhaps noting that it doesn't actually help much as it doesn't seem to off load any valuable CPU
I feel like I've wasted money buying a card I probably wouldn't have knowing what I know now.
well, it was explained in the cuda thread (old forum). Cuda works very well with long tailed programs, for example reverbs and equalisers. Each library developer chooses kernel sizes, sometimes resulting programs are not cuda friendly at all. Alexb consoles are preamp programs, we said several times cuda performs poorly with preamp and compressor programs
wow i've been searching for a day and finally found this post... this exactly describes my problem, but all the search terms i tried previously didn't seem to find this thread. is there anyway we could have a specific Cuda sub forum. it has been quite a pain trying to find info on configuration issues. thanks, Darrell
