Lag in docked mode?

I'm having severe lag on emulators in docked mode. It's weird because the emulators run at 60 FPS in handheld mode. I'm using a 4K TV. I tested Dolphin, PCSX2, and a SNES emulator. Even the SNES emulator was running slow in docked mode. I just updated everything on EmuDeck today.

Has anyone had this problem and fixed it?

Is your upscaler FSR?
I've encountered similar problems when the upscaler is FSR / NIS, docked performance locked at 15fps with audio lag. Changing upscaler to linear solved it but it's certainly a bug introduced after updating to 3.5

Thanks, this finally fixed it. You have to set your desktop resolution to 1080p and play them in desktop mode. I tried adjusting the resolution of games to 1080p in game mode but they still lagged. I think it's a bug with update 3.5.
