nVidia IDE SW driver update! in Processors, Motherboards and Memory Posted January 23, 2007 Good thread, was looking for an excuse to try the NV drivers. Based on a couple of tests (boot time, HD Tach), here's my results (switching from MSFT drivers to NV): * Boot time decreased 7.5% to 80 seconds (from 86) * CPU utilization increased 57% to 3.66% (from 2.33) * All other HD Tach stats showed no difference I tested both boot time and HD Tach 3 times and averaged them. So not a big sample by any stretch. Despite the CPU utilization increase (which I find suspect with such a small sample), I'll probably stick with the NV drivers unless a problem starts cropping up. My reasoning: * System feels a bit snappier (totally subjective, I know) * I like faster boots (even if it is only 6 seconds) * I can turn command queuing off on my Raptor 150. I've seen some results suggesting that turning it off in a non-server environment (me) results in increased performance and less potential problems with the NV drivers. The MSFT drivers don't give an option to turn NCQ off. That's it, cheers.
