This is a Windows 10 Pro VM, which I use to run Topaz Labs Video Enhance AI. https://topazlabs.com/video-enhance-ai/ Topaz Labs offer a free 30-day trial. I have been using this to upscale DVD-quality video (720x480) by 225% to 1620x1080, using the Artemis-LQ model. This typically triggers the warning within a few minutes. (During the bisect I considered a 1 hour run without hitting the warning to be "success.")
