I added a couple variables to my /etc/environment on Arch. Big mistake. My wine fps with dxvk went from 95-100 > 10-14 (World of Warcraft).
The variables shouldn't have had an effect so I don't even know what to look for as the variables had NOTHING to do with wine or anything graphics related... I checked the wiki and didn't catch anything about dangers in variables unless I missed it. It's odd as hell.
I verified, as soon as I removed the lines in /etc/environment and rebooted my fps was back.
Code:
CUPS_SERVER="192.168.1.2:631"
EDITOR="/usr/bin/nano"
That was it.
