I once again post my issue (I read at least 7 other players have simular issues in Steam and PDX forums. So maybe it can be of help.
- I bought Deluxe version and DLC soundtrack at release.
- Installed release version V1.0 launch via Steam, PDX launcher start. Game load. InitGame is 30 seconds visible in loading screen, then it creates checksum and game start.
- Hotfix released. Game stuck at InitGame. Same desktop, same settings. Nothing changed on my site in the meantime.
- Reinstall V1.0 game runs normally. If I compare user folder, the V1.0 user folder contains two folders V1.0.1 and 1.0.2 does not create. Cache and Terraincache. Everything else is the same.
- Installing newer version over V1.0 while keeping those Terraincache and Cache folder in the userfolder will let me play V1.0.1 and 1.0.2.
- I need to actively alt/tab and actively use other apps at the moment Imperator loads InitGame, otherwise it keeps being stuck forever.
- No antivirus here, no ransomware protection, Windows Defender exception for Imperator created both public and private.
Some extra notes:
- Running in fullscreen (not windowed or borderless) result in endless loading screen always, since alt tab also doesn't work anymore in fullscreen mode. So make sure you use borderless mode or windowed mode.
- Having taskmanager open atm I launch Imperator result in direct not responding.
- The only way to have guarantuee to start V1.0.1 or V1.0.2 for me is launch the game via Steam while no other apps are open. Make sure V1.0 is previously installed, make the computer work when InitGame is visible loading, wait 3 minutes alt/tab and chat in Steam a bit and it will continue.
- If I can bypass InitGame I can play hours with good performance and without issues. Also loading and saving works fine.
- Not a single issue with any other PDX game on the same system.
