Audio anticipates video

Just upgraded to 5.0.8 works ok but I have a couple of issues.
1. Audio anticipates video, making hard to know where you are timewise.
2. video problems on the piano roll screen, I have to refresh view all the time.

I did not have these issues on v-3 or v-4 and nothing else has been changed computer wise.

Any Ideas?

What kind of video card are you using?

Thanks, but I think I have it working properly now.
