There’s an air vent that you have your Darkling buddy climb into, and he uses his powers so you can see from his perspective. You use his tiny body to traverse through the vents, but the game won’t let you walk past an invisible wall. This is caused by a similar issue that I found in the PC version of Killer Is Dead, an issue tied with framerate. If your game is getting more than 60 frames per second you’ll be stuck until you enable V Sync. I tried enabling it in game but it only seems to work when running in windowed mode, and setting V Sync through my Radeon Software (Windows) doesn’t seem to help. But switching it to Windowed, getting through that area of the level, and switching back to full screen seems to have worked. I’ll have to try this on Linux to see if Proton will make it run any better, just as an experiment. I might also try tweaking the configs to see if I can get it to enable V Sync in fullscreen mode by changing some convars in one of the ini files, or running a borderless window program. If you’re reading this and have had similar issues check out this link.
Other than that particular snag I’m really enjoying the game! I survived the interrogation scene and have chosen that as my stopping point until I pick up the game again; Hopefully I don’t run into anymore issues.
