Hello @matt8629,
this behavior can have a variety of reasons. To start troubleshooting I would recommend at first to reset the Maya user preferences by following the steps from here: How to reset the Maya Preferences to Default.
This might not solve the issues, but will enable you to work on base of fresh preferences that do not cause additional issues. Since you are using a PC with AMD Threadripper 3960X and 2x 2080Ti, I would suggest to go through the instructions from this article: UI lags or seems sluggish even on fast multi-core CPUs in 3ds Max.
This article is related to 3ds Max, but the machine type is related to the same (superfast) Threadripper CPU. Disabling Simultaneous Multithreading and/ or trying to set the QT system variables would be options that you can try.
Hope this helps! Looking forward to your reply, if you could solve the issues.
Best regards,
Patrick
