I hope this is the right thread to add to... I've been playing gamesnostalgia's download for a a year or two now in Windows 10 and noticed performance problems in longer games. The longer I'm playing, the worse it gets. Task manager shows that Windows Explorer quickly jumps to at least 30% CPU usage, sometimes Desktop Window Manager joins in and causes high CPU as well. When I hit "Save Game", Windows takes forever to show any reaction. Sometimes, the system just goes into shock and I have to force shutdown. Also, from some point, I can't minimize / switch away from the game to the desktop or other windows without waiting forever, sometimes it causes a crash as well.
I've now deleted all files and re-installed gamesnostalgia's update from October 2020 and FoxAhead's CIV2UIA (I hoped the CPU throttle would be helpful). Started a new game, and after 2 minutes, fan started running, Windows Explorer went up to 32% again, Desktop Window Manager to 14% and Civ2.exe changes between 1-11%. Is there anything I can do?
I'm not sure what more info you might need. I run the Launcher with admin rights and compatability was preset to Win XP SP2. Civ2.exe with admin rights and compatability preset to Win XP SP3.
