Because I was fed up with parallels subscription model and they make me pay for the upgrade the non-subscription version with every new macOS release, I dropped parallels for UTM. I barely need windows, only every other month or so and often just for some small tasks. UTM is nice, but performance running windows is waaay below parallels. It is free, however, so I won't complain.

Last I checked UTM doesn't have GPU acceleration. Parallels' proprietary GPU driver is the only reason to pay for it.
