Playback problems MOHO Pro 13

[doremi]

As a workaround for sluggish playback performance in the viewer,
I found switching the apps UI to low res mode works wonders for 4k resolutions.

It's not ideal, but it does the job for now. Works for Moho 12 and 13 (although 13 is a tad slower in everything on macOS).
I'm on a 16" MBPro with a Razer Core X eGPU and a Radeon RX Vega 64 8GB, and I get butter smooth playback with this.
And I switch off GPU acceleration, because it doesn't make much difference and causes display issues with masks and a lot of other things.

You are a Rock Star!! Yes! that does the trick and not noticeable degrade in the image quality.
I am finally full sailing now and learned something. I will stick with 12 for now - it gets all done for me.

Thank you so much!
