CPU + GPU slower than only GPU

Post by bcaroll »

I just got Neat Video and without understanding what it mean (yes I will eventually read the manual) I cranked the radius up to 5.
When I then tried GPU + CPU and only CPU I found that GPU + CPU was 3-4 times SLOWER than only CPU, is that normal?
I have a Q9950 CPU and a 480GTX GPU

What is the frame size in pixels?

How did you measure the speed? Did you use the Optimize tool in Neat Video Preferences, or another method?

If you used Optimize, please post the log from there.

Thank you,
Vlad

I used two methods. Measure how fast the plugin rendered a couple of frames in Premier, then I also used the Optimize tool and I got roughly the same result.

The strange thing is that I cannot reproduce it. When I run the Otimize tool I get different result every time, but now GPU+CPU is always the fastest.

My GPU seems a bit moody.
