Is there a way to make DX12 games run in "true" fullscreen mode?

Just found this. Reg key to enable or disable MPO.
LMAO only thing I found in French: https://www.touslesdrivers.com/index.ph ... _code=7923
Translated mpo_restore.reg will indeed delete value from registry and restore default configuration. So it should be enabled by default! I tried windowed mode - borderless in BF1 DX12 and it was V-SYNC level of lag :lol: 1000 times worse then FSO and DWM! I am on 461.40.

I don't see it either, but input delay does feel like it has decreased with these 461.40 drivers. Of course 'feels' is subjective though.

Yeah depends, I was on these awhile. And depends on game, Windows could activate it in a game x and not in my game... Hope someone will find how to force it. Windows 10 feels like shit on gaming compared to Windows 7!

EDIT: :lol: it works, forget that G-SYNC is enabled only in fullscreen mode by default! Latency is now better than on DX11 FSO disabled! Amazing!

Hmm, not sure it is working, as DWM usage spikes to 15% cpu. I am on i5 9600KF, that's a lot. But it feels better still, than DX 12 fullscreen for sure. I have frame time issues currently so it is hard to tell...

EDIT2: Also I would be interested, if this works in VR. I don't know what mode VR uses, so far didn't notice option in game to change it.

I currently use the 457.30 driver. In terms of latency (461.40) are there any improvements on DX11 FSO?

How would I know :D It is not like I am testing every driver against every other :D

To disable FSO until DX12:

Save as .reg file, then double click, first you can export given key in registry to easily revert changes.

Code: Select all

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\System\GameConfigStore]
"GameDVR_DXGIHonorFSEWindowsCompatible"=dword:00000001
"GameDVR_FSEBehavior"=dword:00000002
"GameDVR_FSEBehaviorMode"=dword:00000002
"GameDVR_HonorUserFSEBehaviorMode"=dword:00000001
To verify this is working, try to change volume, if you see pop out window, FSO is still on!!!

Tho MPO works nice on fullscreen borderless, tried that in another game using Vulkan and input lag is amazing! For that you need 461.09 at least!

I tried to get to the bottom of this for a long time and have given up. :lol:

I remember reading elsewhere that some of the newer games (Or potentially all DX12 if non work) don't disable it because the game literally doesn't have an exclusive fullscreen mode, the fullscreen option in game only works with FSO.

Destiny 2 is DX11 and disabling it does work, but I got a bug quite often where if I minimised, the screen just got stuck in a black box that I couldn't get back into. So I have to force close the game every time. I ended up leaving FSO on because of it.

Disabling it doesn't even work for DX12/Vulkan, so you are safe!

Black screen? Hmm strange, I did not have problems with it so far. Can be game specific. You still need to tick each app in compability tab, so putting this to regedit, doesn't force it on apps.

Yes so now, in most modern DX12 games, you want to leave "Disable full-screen optimizations" un ticked! as this by passes the WDM vsync. more people need to learn this as disabling full screen optimizations isn't the way to go anymore.

What's the issue you're having, exactly? The new fullscreen mode is just as fast as the legacy one.
