Is there some sort of autospliter, or you need to do it manualy?

There is an autosplitter in LiveSplit. To activate it, go to "Edit Splits..." There should be a section called "Autosplitting and load removal by DrLa" Make sure you click the "Activate" button, then it should work.

i tried that right now, but it doesnt work for me. Im really new to speedrunning and livesplit. Help?

Perhaps try to add -gl to your launch options to force Hardware mode.

I have launch options set to -high -gl, activated split and its still not working, I've tried starting/stopping manually but its taking up so much time lol.

if you run the game as administrator then you should also run livesplit as admin

CoF was in fullscreen...XD opp.
