Expected Behavior:
OS UI would run quickly and normally. Gaming would be pretty good, albeit hampered if it wasn't specifically designed to run on Linux. Steam Deck works, why not a reasonably powerful desktop?
Actual Behavior:
All games lag, be it Baldur's Gate 3 or something much simpler like Crawl. Reducing graphics settings do not help. Additionally, just using Mint casually with two monitors causes the entire OS to run slow - mouse stuttering, slow typing about 50% of the time. Have tried different drivers (565, 535), modifying swap amount (now 8GB), different NVIDIA modes, diables Sync to VBlank and Allow Flipping, uninstalled IRQBALANCE, SSD is more empty than full, Feral gamemode w/ Lutris.
