I am running Vegas 16. When I try to edit multiple tracks of 4K the play back
stutters so bad it is unusable and the CPU goes to 100%. I have a NVIDA P2200
video card but when I go to preferences it looks like Vegas is not seeing it.
Correct me if I am wrong but won't the video card take some of the strain off of
the CPU?
I am running a  Dell 3930 with a  Intel Core 15-8500 CPU @ 3.00 GHz and 16 gigs of
RAM.
