Is this still an issue with latest build? https://builder.blender.org/download/

I'll try this one. I'm currently using 440.97.

Can you tell me what driver version are you using? I had 417.something that was probably a year old and then I installed the newest one, uninstalling the old one with DDU and it didn't work.

I don't have any other programs but ZBrush and Blender in my PC, but I'll install the trials to try.

I made this video, I hope you can see the problem. It's the frameskipping that happens right when I start rotating the camera. It doesn't look so bad on video, but it adds up when modeling and it gets pratically impossible to model.

I work with a dual monitor setup, one 4k and one fullHD and don't see any lag in either.
Can you monitor your graphics card and see if it isn't throttling? Does frame drops happen in games or other 3d apps?

A workaround for this bug is switching out and in of edit mode. I assigned TAB to change between modes instead of opening the Modes Pie, so it's a quick double tab to fix.

Just an update. I've tried with the latest alpha 2 build and all 2.8 beta builds after 925380050d0 and the bug hasn't been fixed.
