SLOW ALT-TAB FIX (con: HDR brokes)

[disq]

I'm a bit confused with the "delete-all-refresh-rates" trick.

Can we do this and still maintain G-SYNC? For example, can i delete all refresh rates except 165hz on my monitor and G-Sync should still operate correctly with fps inside the hz range?

I'm a bit confused with the "delete-all-refresh-rates" trick.

Loading ToastyX and deleting all refresh rates except the one refresh rate you want.

This prevents mode-switch blackouts between Windows + Game.

Mode-switch blackouts can occur with:
- Changes in resolution
- Changes in refresh rate
- Changes in sync technology (VRR change)

If any ONE of these happens, you have a temporary black screen (1-to-5 seconds) with an Alt+Tab delay.

The name of the game is to force Windows *AND* Game to have exactly the same display mode. When that happens, there's no Alt+Tab slowness (no mode-change blackout). Games often churn through resolutions, refresh rates and sync technologies -- sometimes changing back-and-fourth, such as launching in 60 Hz then switching to 144 Hz. So you sometimes have 144Hz->60Hz->144Hz churn. Deleting 60 Hz fixes that specific system.

There are multiple tricks to force this equalness:
(A) Using ToastyX to delete unwanted refresh rates except one refresh rate that you want.
OR
(B) Creating a new custom resolution that has only one refresh rate.

Also remember:
- Windows and game must be same resolution, same refresh rate, same sync setting
- If you want to roll back your list of resolutions/refresh rates back to defaults -- then run ToastyX "reset-all.exe" .... That deletes your added custom resolutions & restores your deleted resolutions and/or refresh rates.

Only issue with your method is that adaptive sync now doesn't work in some games(Warzone, Cold War so far tested) and for some reason it thinks it's fullscreen borderless(have an app on my desktop that's always there except when a program/game is fullscreen and in games on fullscreen I still see it)
Also tried resetting NCP adaptive sync settings setting it to fullscreen only and fullscreen and borderless, game settings and in the monitor too etc doesn't work.

There's some potential additional instructions for certain monitors, it's easily overlooked.

For the "delete-all-refresh-rates" trick to eliminate Alt+Tab slowness, you also have to make sure sync technology is the same for Windows and Games.

G-SYNC/FreeSync ON for Windows and games (G-SYNC completely enabled; windowed *and* fullscreen in NVCP)

OR

G-SYNC/FreeSync OFF for Windows and games (G-SYNC completely disabled). Then you eliminate the Alt+Tab blackouts.

The other legitimate trick is the 1920x1079 trick (create custom resolution containing only ONE refresh rate, while also disabling monitor scaling, use GPU scaling -> "no scaling") and also configure similar sync technology as described above. Sometimes easier on certain models of monitors, but for the ASUS, usually the delete-refresh-rates trick is easier than the 1920x1079 trick which is good if the monitor avoids glitching/scaling/blurring.

I have the: G-SYNC/FreeSync ON for Windows and games (G-SYNC completely enabled; windowed *and* fullscreen in NVCP)
except for the game where the game only has vsync as an option and I have that off, I think it's just the game that's funky, other games are fine. Same with this game forcing borderless fullscreen for some reason.
Also with CRU what's the difference having your resolution that you want in detailed, standard or in the CEA place?
From what I can tell having it in the detailed section makes it "native" in NCP.

Some games switches resolutions back and fourth -- for example 2560x1440 then 1920x1080 (e.g. startup video screen) then 2560x1440 (e.g. game screen). This breaks the tricks unfortunately. There are many different little bits that can break this and create the slow Alt+Tab because of the mode-change blackout.

I think all the new games do this... Stupid devs. I wonder why so many people don't even notice this blackouts or they just don't care. I hate web animations because they waste my time as blackouts do. Thanks for the info, you are the real pro in monitors. The forum is great too, no fucking recaptcha. God I wish google to die.

If I play in CS GO on 1280x960 resolution i should add 2 resolutions with fixed hertz? 1920x1080 and 1280x960? Or just 1980x1080?

How I understood it, the delay is caused by change in display mode. The display mode changes when sync, refreshrate or resolution change happens. Like chief wrote:

"- Windows and game must be same resolution, same refresh rate, same sync setting"

It means that you have to have the same resolution in CSGO and Windows desktop if you want to eliminate the delay.

Thanks for the fix! I have win10 though. Been struggling with trying to fix blackouts when tabbing back to Warzone in fullscreen mode. Both game and Windows were set for 1920x1080 240hz but I still had blackouts. My cru was different from what your steps described. Now it's all good. Is there another way to fix it and not using cru?
