Hey yo, always I have my Toribash in the high graphics, today I changed this for a low graphics to remember the old tori, so the problem is that my Tori crashed/stop worked when I try to return in high graphics, why?

well, this happens a lot to me in newer versions.

What I usually do is start a new single player game then try to change graphics to high again, so my computer will have less work. See, if you try changing it while watching a replay it may ask too much effort from your computer to change everything and keep the replay playing at the same time so if you start a new game and turn ghosts off might help. At least it works fine to me

You can also go into setings, under advanced and manually turn on a few settings first so your pc wont have to lead all those things at one time. That should help a bit
