CPU load causes GPU bottleneck?

post #1 of 2
Thread Starter 
ok, so im bringing this up because I was under the impression that the CPU just fed data to the GPU without actually processing it, when my CPU usage goes above 80% specifically on core #2 the GPU usage drops quite considerably when I stress them both. is that just that the bus is too busy or what? im just clearing this up with myself

Be more specific, stress them with what? And if it's a stress test, the stress test is using all of your CPU time and it can't process the data it's feeding to the GPU fast enough.
