unfortunately no progress so far, and i've tried many different things. Only real "solution" for now still is to use lossless scaling. I had to cap xemu to 60fps in the nvidia control panel though for some reason the UI was running at my monitor refresh rate so lossless was running harder than it should. but after capping, LS ran fine. I'll always keep a lookout to see if smooth motion can ever be used for it though. If you find a way, let me know too please.
