I had some issues with lag, here’s some fixes.
Lag Fixing
I’ve noticed that after Afterbirth, many people are getting lag. I had this problem, but here’s how to fix it!
I did 3 things.
1: Turn off vsync. This can be done by going to OS(C:) > Users > (Your User) > My Documents > My Games > Binding of Isaac Afterbirth > options.ini
then set vsync to 0
2: Go into fullscreen. In rebirth, fullscreen was laggy, but now it fixes lag(for me, as least.)
3: Uninstal any mods you had. This is kind of a given.
Hope this helped!
