Hahaha! I've done it!
I have set up my workstation with a Windows virtual machine and a virtual display adapter to use with looking glass so I don't need to plug the main graphics card in!
Moreover, I found a VM configuration that lets me play Elden Ring and other EAC software natively!
Moreover, a quick stress test showed that, even with a P2200, I was able to get good framerates in ER and Looking Glass while watching a stream on another monitor! The memory bottlenecks that plague my old desktop are nonexistent!
I feel good today!
