What version and checksum show on the main game menu?

Are you using any mods?

Please report the temperatures of your CPU and video (GPU) 1/ before starting the game up and 2/ after say 20 minutes' play. If your PC's vendor has given you no way of reading temperatures, install SPEEDFAN or GPU-Z.

My apologies, too many threads! I meant to go into EU4's setup.log , search for "checksum", and paste that line only in here.

Go to MyDocuments EU4 and delete settings.txt and /gfx/ , and let the game recreate them.

If that doesn't help, Try a full clean reinstall: move any valued save games elsewhere and uninstall the game from within Steam. Then manually delete ALL the EU4 directories from under BOTH the Steam and MyDocuments folders. Now reinstall the game from Steam, and run the Verify just to make sure it all came down properly.

Thanks for the update, I've put it in the Known Problems thread. Please report this to Comodo as a clear bug.
