In a post on the download page, David Grover was having trouble getting today's game to display properly in Win11. I carried it over to my wife's PC to check it out...
Had the game, not listed as collector's edition, from GOTD in 2015. That version seems to run fine. In today's version a few of the files are newer [most are still 2012] and the new game's folder holds a bit less than 100MB more. Back in 2015 would have used the Compatibility Troubleshooter in Win7, so nothing listed on the Properties -> compatibility tab for the game's .exe file. For today's game, since the troubleshooter's not working, on the Properties -> Compatibility tab for game.exe I set the Compatibility mode to Win7, checked Disable fullscreen optimizations, & after clicking the Change high DPI settings button, I set the High DPI scaling override to System enhanced. It's possible that one or more of those settings is not needed, but it's a habit. At any rate the game runs / displayed fine in Win11 23H2 on a 1080p screen.
