I am not sure those hot fixes will help Vegas users, but thanks for the heads up.

@OldSmoke: Thank you. Since I just installed the Gr.card I have only the newest and the one before that - which version would you recommend, please?

Excuse me for butting in: https://www.vegascreativesoftware.info/us/forum/bug-defocus-fx-crashes-vp14-down-to-svp13-and-svp12--105099/#ca649868

I installed the hotfix referenced in this thread which updates the driver to 378.57. It does not address my original issue. I rolled back to 376.33

Hi!

I read this thread and others that recommended the AMD RX480, so I got it installed last week. My old one was Nvidia GeForce 970.

Already I can see the rendering speed has increased, or so I think at least. Right now I render some fourty seminars I filmed last week, Each one is around an hour long. I first used Sony AVC mp4 without GPU acceleration and no Dynamic RAM preview, and it took a long time, and the CPU was used to around 40%. Then I used MC mp4, switched on GPU acc and set Dyn Ram Preview at 200 MB - and Vegas crashed after a few seconds. I changed the Dyn Ram Preview to 2000 MB and started rendering again. (GPU on) It worked perfectly. Renders smoothly and quicker than AVC and the CPU uses all 12 cores to almost the full (80-90%).

So I'm happy with that.

I am not sure if timeline preview has improved. Have yet to test it more extensively. A quick test on a video project didn't show any improvement at all compared to the old Nvidia. Let's see.

And: Is there a way to monitor the GPU usage? I can see my CPU with its 12 cores in action, but don't know where to see the GPU action.
