Fixed!!!: Solution- Open Registry Editor, look for the Enterbrain folder in Computer\HKEY_CURRENT_USER\Software\ then delete it. Files are likely corrupted. Restart pc, and reinstall game for good measure, launch game, fixed.
Played demo a tiny bit awhile ago, same pc and everything and wanted to try demo again before buying the game, game is now running very slowly and very low framerate 1-4fps. took about 30min before i could get to the reaper for him to start talking. I've restarted pc, turned everything off, set cpu priority and affinity, checked gpu, turned off everything on pc but game, no luck. Also uninstalled and reinstalled multiple times. Any advice on why this might be happening? I'm using the itch.io app and thats the only system application that has any relevance to the game that has had an update?
Edit: also i have done the _ResetRMsetting.reg. Game is also always in windowed mode by default, i think 680x480? which I saw in faq and led me to check that setting reset. Have also taken to just launching game by its .exe instead of through the itch.io play button.
I have also tried the older outdated demo version too and same issue. I know the demo hasnt been touched in awhile so its something on my end but virtually nothing has been downloaded or changed on my pc from back when i initially tried the demo. :( It is also currently just this game, other itch.io games are working fine still.
