Best GPU Setting for Hyperworks

I start having problems with hyperworks when I got this workstation with Quadro P2000 with 4k display.

This workstation should run hyper blah blah with ease but I experience the other way.

Sometimes when I open a file, I see only black workspace. Sometimes, no model or weird texts, misplaced tools, what the heck are those?

What is the best GPU setting for hyperworks/view using Optistruct as the solver?

Please help before I throw this workstation away due tofrustration /emoticons/default_sad.png' srcset='/emoticons/sad@2x.png 2x' title=':(' width='20' />
