OS works with big lag during CUDAKernell execution

my OS is 32bit winXP SP3
I've noticed that during kernel execution OS works with big lag (about few seconds). Is this normal or not?
P.S. Someone, take a look at my previous question :-)

32-bit Windows XP CUDA drivers don't support TCC mode, which may be contributing to your problem. The Windows 7 drivers do. TCC allows the CUDA card to run in a "Compute mode", which removes it from window-rendering duties:
There is also a configurable timeout for CUDA kernels to start: http://www.mathworks.com/matlabcentral/answers/22047-cuda_error_launch_timeout

Is your CUDA on your graphics card that your desktop is on? If so then have a look at http://www.mathworks.com/matlabcentral/answers/22047-cuda_error_launch_timeout
On the Windows Vista, Windows 7 operating systems individual GPU kernels running on GPUs that are responsible for desktop rendering are limited to a 2 second runtime.
The implication (to me) is that kernel operations or rendering could be delayed by about 2 seconds.
