Here are these filesI don't know what would stop IR, Stellaris and EU4 from running but not affect CK2. Clearly something different about this computer!
I'm actually surprised the MSI gaming app didn't help, that is know to affect EU4 at least (although also CK2).
Let me have look at new copies of these files please:
- dxdiag
- speccy
- EU4 settings.txt
- All files in the eu4/logs/ folder over 0 bytes.
