GPU acceleration randomly diappears since updating to Premiere Pro 15 (now on 15.4.1) from 14.9. When switching to another Premiere Project GPU Acceleration sometimes is not available anymore and grayed out. Restart of Premiere makes no effect. Only restarting of the PC helps but cannot be the solution. With 14.9. everything was ok - never had a problem. NVidia Driver is updated. Adobe Suite completely uninstalled an reinstalled.
Unsing Windows 10 with the latest Update. Nvidia 1080Ti
