Windows 11 and Cities Skylines 2, not so good.

[DarkMerl]

Thought I would share my Exp with this;
Setup: PC - AMD 7900XT (liquid cooled) on a Aorus 670xt Elite, 64GB ddr5, AMD RX6800XT, and a 850PSU to push it all, OS windows 10.
While I knew that Windows 11 is pretty much just a testing OS (gonna have to wait for windows 12, or whatever they are gonna call it, to use the actual features), I updated to windows 11 to see if there was any performance gains to be had, quite the contrary, started with random game crashes 30-40 minutes into a gaming session, then progressed to full blown PC shut down, after the second shut down, I wiped the drive and put Windows 10 back onto the PC, easy enough to do. (Note 1)
After multiple 2-3 hour gaming sessions without so much as a graphics hickup, I am posting this.
Game is Vanilla mode, only mods are the maps I made and the official asset packs.

*Note 1* My background, I have built numerous PC's over the last 30+ years, so the drivers were up to date on both OS's and systems during the tests, and game play.

So, where I saw the most crashes happening during game play was with the farms and drawing out the lot sizes, that tool seems to have an issue.
Windows 11 seems to allow the system to overheat causing a shut down, while this is intended behavior (the shut down part), the system should not have been allowed to get to that point, it lost communication with the fans and temp gauge for some reason. Haven't run into any issues like that with windows 10.
Not sure if there are other issues, but just keep this in mind if you are running on a Windows 11 system.

good to know, its been in the back of mind to upgrade to 11, think I'll put off for another year - thanks for sharing

Good for you. I play without any crashes on Win 11 as long as I want to, be it 8 or 12 hours on one session. One would quickly think that it's not exactly the Windows version but drivers etc.

I use 7900XT to play, and as soon as I enter the game interface, the hotspot temperature is directly 95

I've not had any issues running Windows 11. I've had both an AMD and Nvidia GPU Both seem to run Cities skylines and Windows 11 fine.

Do you know if you were on the 23H2 or 24H2 version of Windows 11? Many games have been having a few problems with the 24H2 Windows update.

For the hotspot, Yes when I had the Sapphire 7900XT I saw the temps skyrocket. The best way I found was to limit the FPS.

On the 4080 super, The temps don't really seem to be a problem. But I still set the FPS limit in-game, So that could be it.

Not sure of version number, I updated via windows 10 update, played on that and had a few crashes, so wiped, and installed latest version from MS website, with clean install and updated drivers, had 1 crash then the system shut downs, thats when i wiped again put windows 10 back on and after all the updates and driver installs, I am back to gaming without issues once again.

Edit: If History has shown us anything, it's that, any new Windows OS, when they try and put in all the new features, ends up a total mess, while users are finding all the problems, then either a new version comes out if the problems are significant enough (windows 8 -> Windows 10), or a hugh SP patch (WIndows XP SP1), comes out if the problems are less numerous enough to warrant that route, so far, I say a SP is coming for Windows 11, so one should probably wait until after that release to switch over.
