Okay, this is driving me mad. I have a Radeon HD 6790. After first installing Vegas everything was working fine, acceleration was great, and gave me a huge performance boost in preview and rendering. Then I ran into a video file that caused buggyness in the acceleration, with random blocks and green frames appearing when playing that file. I turned acceleration off just for working with this project, everything worked well (without acceleration), I finished the project, exported it, all is well. Now I go to re-enable my hardware acceleration – and it’s not there anymore! Now all I get in the list is “off”! Updates Vegas to latest build 510 – still nothing. Updated video drivers – still nothing. Removed and re-installed – still nothing!
WTF?! It was working great just yesterday! Nothing changed! It’s like after turning the feature off, it got removed from my system… What the hell, sony…
Anyone got any ideas?.. I’m at a loss here.
