Hi there, this is what i have done to completely remove the horrible stutters of callisto protocol from my past experiences with unreal engine 4

you might have to enable hidden folders on file explorer

go to C Drive then appdata\Local\CallistoProtocol\Saved\Config\WindowsNoEditor\Engine.ini

in this file your going to erase everything in it and then copy and paste in this row of commands here

then once you have pasted this in save the file and right click on it and then choose properties, on the bottom of the properties tab check the box that says read only and press apply,

once you click apply you can press ok and close file explorer and launch the game, then run a benchmark and you will see a night and day improvement in both fps and stutters.

hope this guide was of some use to people very frustrated with this games performance,

here is another bonus mini guide to get the game to load in under 10 seconds

go to

your steam folder location. Steam\steamapps\common\The Callisto Protocol\TheCallistoProtocol\Content\Movies

and your going to delete a few files, they are called

LoadingScreen_5sec_notext.bk2

Krafton_SDS_logos_4k.bk2

Intro_logo_Krafton_SDS.bk2

Unreal_InstaLOD_logos.bk2

Unreal_Logo_4K.bk2

Wwise_InstaLOD_Logos_4K.bk2

AMD_Logo_4K.bk2

Bink_Krafton_SDS_Logos.bk2

this trick works by bypassing the unskipable intro videos that have the developer logos on them.

in my testing i got about 10 seconds loading time on a gen 3 nvme ssd but it should be a little shorter on a gen 4 ssd or less than 15 seconds on a sata ssd.
