Hi, i am sorry if i revive an old or dead topic, but this was one of the best results google had to offer!

So i used to run a i73770k with a gtx680 and Vegas Pro12, i upgraded my pc to i74770k with an gtx980 and Vegas13.
Since then, i cannot use GPU acceleration anymore (which is mostly annoying for the video preview on 2nd screen).
Vegas does not only crash randomly during preview but also durin redering.
Once i set Gpu acc to OFF everything works perfectly.

I of course tried with my old Vegas12.
And i tried to change the display to 1screen only during the render, and tried to set the preview window to screen1 instead of 2, nothing helped.

But just read this:
[John Rofrano] “Well… the problem with the 600/700 series cards is that they are based on the new Kepler architecture and Vegas Pro 12.0 was written for the older 400/500 Series Fermi cards. I’m guessing it will take a while for the software to catch up to the hardware.
“

And that was the first idea that came to my mind when i started having that issue.
Could it just be a conflict between Vegas and the very new gtx900 gerneration?

Thanks for any input!
