Viewport Behaving Sluggish when changing Windows Screen Modes

Kid_Kaboom

Hello! I'm sorry if this has been mentioned in another thread, I looked around for it but couldn't find anything about it.

I'm using standard Daz 4.8 which normally works really well. However if I switch screen mode from Computer to Duplicate (for watching Netflix etc) and then go back to Computer screen only, the Viewport in Daz 4.8 becomes sluggish and unresponsive. Even without a model or scene or anything loaded, it behaves as if the frame rate is 0.1 instead of the normal fluid one. My workaround for this is I either have to continue working in screen Duplicate mode, or reboot the computer if I want single-screen only.

I wonder if it has something to do with my monitor being 144hz and the TV 60hz. In duplicate mode they both run at 60hz and Daz behaves fine, but as soon as I switch back to the PC screen - with 144hz - the Daz Viewport as mentioned becomes unusable (UI reponds fine though). However if I reboot with 144hz screen only OR go back into dual screen with 60hz, Daz works perfectly fine.

This is not a huge issue but it's a little annoying at times having to reboot to get the full benefit of 144hz in Daz 4.8 again. I'm wondering if anyone has a similar issue or any suggested fixes for this? I've only found this issue in Daz 4.8 and Blender, other programs and games are not affected. Thanks for any help or input.

That sounds a lot like it's an OpenGL problem...Studio and Blender pretty much use the same OpenGL stuff for the viewport display.

Alright, thanks.That at least gives me a clue and I'll see if I can figure anything out.
