Alt-tab freezing needs to be fixed

If you can, please send the .clog file from the WarThunder\.game_logs folder here. The file should be created when the game closes, for example due to a crash.

i’ve used ctrl+alt+del for so long and then one day i accidentaly discovered ESC + CTRL. saved the hassle and it wont fk up my game anymore.

I’m also using double monitor setup. 4k and 3440x1440. But to my knowledge, some singe monitor setups also have the same issue.

I hadn’t realised this could happen with a single monitor either.

Thank you for reporting it.

Another point of interest is that everyone seems to be using WQHD (1440p) monitors.

Has anyone experienced the same issue using only Full HD or 4K monitors?

I play on full HD et constant Alt tab (EC naval or air sim) and i never crashed doing this

Thank you for the report.
It seems it doesn’t crash at Full HD resolution, but was that single monitor WQHD?

Somehow, this issue seems to depend on the communication environment with the server.
Today’s freezes are occurring every five minutes, which is terrible, but the server is equally laggy and awful.
When lag occurs and you press Alt-Tab, it freezes 100% of the time…

I’ escaped the problem for a few months only for it to return again after a while. Ofcourse the countless reports done, they all go ignored or get closed.

They keep blaming windows for it, which would be fair, except its only their engine that has problems with windows, it is only their game which behaves like this. So it clearly is on them to fix this.

I don’t have any tips regarding how to stop the freezing from occuring, but pressing Win+Ctrl+Shift+B will reset your graphics drivers, usually fixing the freeze after a moment and saving you from having to close the game (though your texture quality will be reduced because the game does that after the graphics drivers hang)

Someone even mentioned having the same issue in Aces of Thunder, which I assume is running on the same engine.
I guess it was @joshje100

Yeah I had that issue a few times in the first week of playing it but I haven’t experienced it since. Although to be fair I haven’t played it much since then.

But seeing as both games are built on the same engine I’m certain it’s an issue with the engine. Just not in my scope of things to be able to figure out exactly what.

I’m not a programmer either, unfortunately. But with Gaijin’s approach to these kinds of issues, I try everything possible to rule out any fault on my side. Last year I already replaced my entire PC — almost everything is new now, except for the keyboard and monitors. The only other thing is Windows 11, which could theoretically be the culprit, although it’s a fresh installation with a new license (though the license itself shouldn’t matter).

I’ve also noticed that the issue seems to fluctuate — sometimes it gets weaker, other times it becomes more frequent. I have no idea what it depends on. Sometimes I can play for half a day without anything happening, and then a few days later the problem starts occurring more and more often, only to disappear again after some time.

Leaving problems unresolved is absolutely unacceptable.
If this has been going on for two years, they need to fix their own game engine instead of blaming Windows.
Useless brilliant GAIJIN engineers.

This doesn’t work in my case.

Odd, it should make a beep sound followed by your screen turning off for a moment

It does, but the game is still frozen.

I see… Not sure what to say then, maybe just waiting a moment will fix it

In Poland, we have a saying: “Hope is the mother of fools.”

Yesterday I added a new entry to the system registry:
(HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Dwm, new DWORD OverlayTestMode set to 5), after which the computer needs to be restarted.

This entry disables the Windows MPO (Multi-Plane Overlay).

In addition, I disabled G-Sync in the Nvidia settings (the equivalent of FreeSync on AMD GPUs).

So far, the game hasn’t frozen yet.

This is a screenshot taken immediately after the game froze when I pressed Alt-Tab.
The textures around the F-2000’s engine are corrupted.
I’m not sure if there’s a connection, but there may be issues when loading models in WQHD and 4K resolutions, which are higher than Full HD.
I’m playing at WQHD resolution.
