HD preview not HD

At least not on my VP.

Try the other GPU selections, under OPTIONS | ADVANCED. Be sure to restart VP after making a change.

Tried, same result for me, blurry preview in HD preview. 🙁

It's a mystery. You can see how clean it is above - with a grab from the full-screen window.

yup, as you know I even tried uninstall and reinstall with the same result.
