You could use oprofile to find out where the CPU time is spent - this behavior can be caused by a lot of issues.

Does the Cuda client work now? If so, it would be cool if we could include the wrapper in Wine, or get it into a shape to make it easilly redistributable and installable next to Wine.

Subject: Re: CUDA wrapper

It seems when using this wrapper and a cuda enabled program, it causes the program/wine to use 100% of a CPU core, while running in windows the FaH GPU client only takes around 10-15% at most of a CPU core. Any ideas why the sudden jump to 100% use? It makes the systems most unusable in the normal sense, as a desktop.
