Your mothers main.
Yeah, I believe it is the rollback implementation. On the other hand I played plenty gg+r and KI, power rangers and sg and never noticed it even in the slightest. It could also be the combination of both other connection and shitty implementation of rollback on pc. I watch my fps counter like a fucking hawk. This would happen in all configuration of settings I tried.I was so frustrated with hitching online that I slowly rebuilt my entire computer and home network trying to find improvements. Sometimes I thought it was me and sometimes I had to wonder if it was other people being incapable of noticing they weren't actually running smoothly. Sometimes it ran great, and sometimes not. Eventually it was working well enough I stopped caring as much and just accepted the lot.
The rollback stuff adds some murky stuff to figuring it out because it puts more stress on the system online doing the rollbacks that it doesn't have to pay a cost for in single player. But on the flip side, you could also have a slower system on the other end of the line and your faster system has to keep injecting pauses to let them sync back up meaning it sucks to be the better system.
I built a whole new rig but I am not gonna install mk11 just to see if it fixed the issue the game is dead to me lol. I just hope we have no problems with strive in that department.
