Crash with dim selection on egpu

Hi Im getting crashes relating to dimensions on the latest WIP while using egpu. I know its not a standard setup but it was working fine before and theres also no problems on rhino 6.

Hardware is Thinkpad X1E with GTX1080ti egpu with latest gaming drivers (having issues with studio drivers and adobe)

General single dimension selection are sluggish but does not crash. Selecting multiple or using Seldim will crash rhino every time.
Rhino will freeze and gpu goes full throttle, then rhino continues to use up physical ram until it crashes. Whole process takes around a minute from freeze to crash.

Im just using R6 for the time being so theres no rush on a fix, although I have become quite accustomed to R7 so any help is much appreciated!
