laggy substance painter-workstation

How to improve performance? So the following seems to lag 

• Undo/redo functions 
• Assets tool bar/Brush icons are stuck loading 
• Drag and drop- Change material 
• Progress bar stuck on any operation 
• Even on demo projects at 50mb-100mb file 
• Brushes/materials wont paint and brush hovering on model is slow 
• Projects even at 1024 texture paint are slow 

Things I tried 

• Raised cache to 2000mb even maxed out at 9999mb  
• Created a virtual cache on a 2tb nvme drive that is 32gb in size 
• Uninstalled  
• Restarted and only launched substance 

How can I improve performance? its unusable, only substance is acting up. I work with much bigger files in keyshot with no problem.

System specs 

I have 4 2tb nvme drives 

88gb of ram 

Xeon 2235 6c/12t  

Quadro Rtx  8000 48gb 

any help would be appreciated, i am in trial mode and lately it hasn't been a warm experience to want to purchase.
