CK2 freezes computer

[Dalamar80]

After a couple of years break from Crusader Kings 2 I decided to take it up again since it`s a classic. Since my hardware has been upgraded and the game patched quite a few times since I last played i can`t say where the problems started.

The problem is that the game on random intervals freezes my entire computer which becomes totally non-responsive other than the music still going, and I have to restart with power-button.
Sometimes I can play for 6 hours without any issues, sometimes the pc crashes after 20 minutes of running the game. Also I am running no mods.

Have tried updating to the newest graphics drivers, running as both admin and in Win7 compatibilty mode, repaired and re-installed the game, and anti-virus/firewall isn`t meddling with the game, Temperatures isn`t a problem, never been above 60C on neither CPU/GPU while running the game.

You don't need to run as Admin, nor any compatibility mode.

Please do a full **clean** re-install:

- move any valued save games elsewhere
- "uninstall" in Steam-CK2
- manually delete both the Steam/SteamApps/common/CK2 AND Documents/Paradox Interactive/CK2 folders - In particular make sure there are no files or folders left under either the Steam CK2 or Documents CK2 locations, before installing again.
- re-install game in Steam, run a Steam Verify when done.
- add ck2game.exe to the exceptions list of your antivirus app; ESPECIALLY if you have Windows Defender, add it to the Ransomware "Apps Allowed Through" list.

THEN Right click on c2game.exe , properties, compatibility. Tick "disable fullScreen optimisations" untick every other box in that dialog, Apply and exit.

Edit that settings.txt to say:

refreshRate=60
fullScreen=yes
borderless=no

vsync=no

Does that help? If not please attach new copies of those files please.
