hello, since several versions (i think it starts at V12 - but not sure) i cant change the gpu back, if i changed it once in the video preferences:
GPU acceleration of video processing:
i have 2 gpu in use. one of it isnt connected with a monitor (2) because i just use it for rendering in other applications (3d-software).
after installing vegas, automatically gpu1 is chosen, thats fine. i see video previews and everything works.
if i change to gpu2, no preview from the timeline is working. if i want to change the gpu back to 1, vegas denies this step and always switch back to gpu 2. this is crazy, because i cant preview and render anymore.
i use an actual win10pro with the actual vegas 16.0 build 361 (but this problem exists since version 12)
i tried several things:
- start vegas as admin
- use nvidia control to give vegas just 1 gpu
- set to none, then back to gpu1
- restart several times and change to gpu1
- install different build of vegas (update)
nothing of the steps works - i always end up with a selected gpu 2 and no preview.
i have to reinstal vegas completely to get the original setting back.
is there any way to avoid the reinstallation? i just have to get back my gpu1 again for previewing.
