NOTES: Black Ops 3 with the NTSYNC driver has far less stutters/hitches than previously and we get a much smoother experience while playing compared to without.

If you would like to use NTSYNC, update your Steam Deck to SteamOS 3.7.20 and apply GE Proton 10-32 with my guide here – https://www.youtube.com/watch?v=wEtXtjHI44g
