Crashing when alt-tabing with fullscreen exclusive

[sunshy]

It've crashed 3 times already.

Since borderless locked at 60fps (wtf) I need to use exclusive. But it just crashes.

Alt-tabing on main menu? Crash
Alt-tabing when shaders compiling? Crash

Seem like i'm not alone, mine only crash when I alt tab or switch from exclusive fullscreen to any other mode, but once it crash in exclusive fullscreen, launching the game next time without change it back to windowed or fullscreen, the game will CTD at intro startup.

My current solution right now is to change from exclusive fullscreen to fullscreen with the launcher then change to exclusive fullscreen after you're in game in the main menu. However even if you quit the game normally, if you're in exclusive fullscreen, the game still crash regardless, and you have to redo the fullscreen setting again before you launch the game.

D3D12 doesn't have Fullscreen Exclusive. Despite Nixxes calling it this in all of their games, it's just borderless fullscreen window with the desktop resolution and refresh rate temporarily changed and restored when you alt-tab.

Don't use "Fullscreen Exclusive" because it's not a real thing.

I have no idea what the commenter above thinks they're talking about, but regardless of whatever Fullscreen Exclusive mode in HFW actually is, it results in noticeably improved performance versus regular Fullscreen mode on my RTX 2060 rig. The other option gives me microstutters something fierce, while exclusive mode is smooth as greased butter. You should use whatever option best suits you, they put it there for a reason.

The only thing I could imagine happening that in fullscreen, itll run in headless mode for windows itself. So that its not using VRAM for the desktop (can be couple hundred MB's). When you alt-tab, it quickly has to store it in a capacity that is already satured by the game (if you have 6 or 8GB's) and it crashes due to lack of resources.

Try forcing it to run at the lowest possible settings, and see if it still does it.

No, sorry to be the bearer of bad news here, but there is no Fullscreen Exclusive in D3D12.

What you are experiencing is placebo effect. The Fullscreen Exclusive option does only one thing, it allows Windows to change the refresh rate and resolution of the desktop when you Alt-Tab.

D3D12 has NEVER had Fullscreen Exclusive. Developers can call their option Fullscreen Exclusive, but that just means they misnamed it.

Read the very first paragraph.

Direct3D 12 doesn't support full-screen exclusive mode (FSE).

I guarantee you D3D12 does not have Fullscreen Exclusive, I am a developer who works with D3D12. Nixxes is unfortunately confused and now because of their confusion, consumers are also confused :(

Read the end of the third paragraph as well:

These changes can be made by an app without the use of this method

A borderless fullscreen window is the exact same thing, only without the annoying resolution and refresh rate change when alt-tabbing. And critically, in this case, without the crashing.

Tl;Dr:

The user is complaining about "Fullscreen" mode being limited to 60 FPS and that is because their Windows desktop is only running at 60 Hz, which is frankly silly.

OP needs to set their Windows desktop to run at their full refresh rate, rather than 60 Hz. It will make their entire system more responsive, and most importantly, avoid the need for this misnamed and crash-proned graphics option.

Its normal for game to not be happy about alt-tabbing when i Exl Fullscreen. That's why you have the option of Borderless.
