I have a v1 modded Switch and I just want to start off by saying that I’ve already tried THREE different SD cards (two Sandisk and one Samsung cards), a fresh install of CFW and I’m still running into this problem. I’m running Atmosphere CFW and games installed on SD seem to stutter no matter what I’ve tried, docked and undocked. Game cards run perfectly fine. I’m not using any background apps like Tesla or sys-clk so there isn’t really anything to disable. Any help is greatly appreciated.
