Kingdom Come Deliverance wont start

No matter what settings i try or proton version it wont start. This pop-up banner shows up for a few sec and then it closes down.

install d3dcompiler_43 and d3dcompiler_47 through winetricks

colossal-harlequin•1/29/25, 5:02 PM

might also need vcrun_2015

wispy-oliveOP•1/29/25, 5:04 PM

Did that and now i'm getting this:

colossal-harlequin•1/29/25, 5:05 PM

that ain't right

colossal-harlequin•1/29/25, 5:05 PM

i have a similar gpu, i'll see if i can get it running

colossal-harlequin•1/29/25, 5:21 PM

launched without issue, but when i tried to minimize it during the opening cutscene i got a different crash to yours
i'm repairing it now, i'll let you know if there's anything different

colossal-harlequin•1/29/25, 5:24 PM

this worked for me
frustratingly, i can't tell you what packages were installed because i have the option for known fixes on, and that doesn't show in the logs

awake-maroon•1/29/25, 5:34 PM

there are no fixes for this game in the repo https://github.com/Heroic-Games-Launcher/known-fixes

awake-maroon•1/29/25, 5:38 PM

the game should just work out of the box

this error doesn't look unique to linux

awake-maroon•1/29/25, 6:12 PM

@TimeFreeze have you tried repairing the game? it's in the 3-dots menu in the game page

wispy-oliveOP•1/29/25, 7:30 PM

Tried that, still complains now that my GPU is unsupported.

nursing-lime•1/29/25, 7:46 PM

check winecfg to see your windows version setting. if it's not already 10, change it to 10

wispy-oliveOP•1/29/25, 8:39 PM

Why on earth was it set to Windows XP. Okay now the Unsupported GPU error is gone but it still wont start.

there is a bug in heroic 2.15.2 that, in some cases, when using proton+umu, the game redistributables are not installed properly

maybe you can try deleting the prefix /home/timefreeze/Games/Heroic/Prefixes/default/Kingdom Come Deliverance/home/timefreeze/Games/Heroic/Prefixes/default/Kingdom Come Deliverance and then run the game using wine-ge-latest

or you can try downloading a build from github maybe

wispy-oliveOP•1/30/25, 8:45 AM

Deleting the prefix and running via wine-ge didnt work either. Honestly i have no idea whats wrong with Heroic. If i run the Executable via this it works just fine. But if i want to run it via Heroic or as a shortcut in Steam it just wont start.

wispy-oliveOP•1/30/25, 8:57 AM

It only happens with Kingdom Come Deliverance btw. Other games run just fine.

radical-lime•1/30/25, 9:42 AM

are your flatpak runtimes up to date?

wispy-oliveOP•1/30/25, 9:43 AM

Should be? When i run flatpak update it says "Nothing to do."

wispy-oliveOP•2/1/25, 10:20 AM

Honestly no idea what’s wrong on my Heroic installation or whatever but Heroic simply refuses to launch the game. If I launch it with something else as mentioned above or now in my case with GOG Galaxy via Lutris it works without any issues. But with Heroic? Doesn’t start not sure why. But whatever I guess now i can play it and get my Achievements at least.

Add

PROTON_LOG=1

PROTON_LOG=1

env var and try running it like that

dry-scarlet•2/1/25, 10:49 AM

It should create a heroic0 log in your home

dry-scarlet•2/1/25, 10:49 AM

Which should have necessary and useful info

wispy-oliveOP•2/1/25, 12:33 PM

Should be this one:

dry-scarlet•2/1/25, 1:36 PM

It does seem like d3dcompiler issue

dry-scarlet•2/1/25, 1:37 PM

Lutris is immune to such stuff

The game will show the loading dialog and then immediately close. This is true if I launch right from my installed files, or Heroic, or Steam. But I can launch it from GOG Galaxy.
