I’m having the same issue on my end. My emulated games through Emu Deck run terribly now without VRR enabled, and even if if do manage to get VRR running by restarting the deck, there is a huge delay before I am finally able to get it to display on my LG C1.

The official Steam Deck Dock. It’s wildly inconsistent, and I always have to fiddle around with it to make the input lag somewhat palatable while gaming, although it is still omnipresent. I wish valve would improve upon it, but it still just feels like an afterthought if you’re just trying to consoleize your PC gaming experience on a 4K OLED.
