Street Fighter V is known to have massive netcode issues that cause one-sided rollback, among many other things, making the online experience frustrating and unenjoyable. These issues may have become a thing of the past, at least for PC players, thanks to a recently released mod.

The mod, created by Reddit user Messatsu, introduces some netcode improvements which make the game run great online for PC players, fixing many of the issues that have been present since launch. The mod, unfortunately, causes massive roll-back to PlayStation 4 players, so it is advised that matchmaking is set to PC only to prevent console players from having a terrible experience.
