This never happened before with other drivers. It started doing it with this new one. Just reporting it.
I can open sony vegas just fine. The problem is when I hit play and vegas starts using the video card to render the preview. I was using mp4 and hevc videos
my bad. I was about to post my dxdiag and I saw that I have memory paging was set to off. It works amazingly well with gaming and other applications. But, when I set it so that windows uses what ever it needs the problem completely went away in sony vegas. Im so happy!!!
