SNES Games in RetroArch Play Slow in Troubleshooting Posted January 4, 2017 · Edited January 4, 2017 by jdubst It's a Samsung UHD 4k 6290. EDIT: So I found out how to enable Game Mode. I had to make the TV recognize it as a console... which is a bit odd, but it works. Now when I try turning off Threading, it crashes RetroArch and doesn't save it... how can I turn this off without it crashing on me? EDIT 2: So I just redownloaded RetroArch and put it in the same location. So Threading is off; however, still getting the crazy lag. So for now, I'll just stick with it being on.
