It’s still usable, for sure. The Bazzite team back ported the WiFi and BT patches, so those function. But if you rely on reducing refresh rate to save battery like I do, that can be a big one.
The audio issue isn’t too big of a deal, you just have to do a full reboot to go back into game mode. Just takes a few extra seconds.
But if you already have an LCD, I see the wisdom in waiting for the team to iron out OLED support.
