Hi all, I'm still using the 2.6.8.1-1.520.1vR9.ll.rhfc2.ccrma kernel, and have my video card unthreaded. My question is: does an app have to be specifically designed to take advantage of unthreaded devices? Or is it as simple as unthreading the device by doing a "echo 0 > /proc/irq/10/nvidia/threaded"? I want to make sure my video card gets first preferece on the pci bus to avoid dropouts. Rick B
