Control panel G-sync

Every time I set it to "Enable for windowed and full screen mode" leave the app and come back, it goes to to full screen only. LG 27GS95QE-B

just to be sure, are you able to apply game profile changes normally?

if not:

If you're encountering issues with the NVIDIA Control Panel unable to apply settings with an "Access Denied" error, or NVIDIA App settings changes/DLSS overrides automatically reverting, please try an older driver.

• Download a suitable older driver. DO NOT RUN THE PACKAGE YET.

• 40 series and older: https://www.nvidia.com/en-us/drivers/details/230093/

• 5080 and 5090: https://www.nvidia.com/en-us/drivers/details/240547/

• 5070 Ti: https://www.nvidia.com/en-us/drivers/details/240920/

• 5070: https://www.nvidia.com/en-us/drivers/details/242141/

• Download the NVIDIA App. DO NOT RUN THE PACKAGE YET.

• https://www.nvidia.com/en-us/software/nvidia-app/

• Download the manual version of DDU.

• https://www.guru3d.com/download/display-driver-uninstaller-download/

• Disconnect from the Internet. Use another device to view Discord, or screenshot these instructions.

• Use the manual version of DDU to fully remove drivers. Extract all files from the DDU zip file, run the self-extracting archive EXE inside it, then in the newly created DDU folder, run Display Driver Uninstaller.. Accept default options without changing anything when the settings window shows up, and select GPU in the drop down at the right, then NVIDIA (if it selected something else, usually laptops with AMD iGPUs). Click Clean and restart at the left.

• Once the PC restarts, run the driver package installer you downloaded in the first step. When prompted, install only the driver, and do not let it also install NVIDIA GeForce Experience or NVIDIA App.

• After driver installation is complete, if desired/needing DLSS overrides officially, also run the NVIDIA App package installer.

• After the NVIDIA App has finished installing, but before opening NVIDIA App, reconnect to the Internet

Check if it's now possible to make changes to NVIDIA Control Panel game profiles and NVIDIA App as expected.

Thank you for trying to help me. I did not follow these steps 😅, instead I just rolled back a driver and it worked.

I have RTX 2080s. The driver that would revert the changes is 572.70 (March 5, 2025). I can’t find the name for the driver that I rolled back to but it was released in March 3

I rolled back using device manger

Never use the rollback option in Device Manager; this will break the drivers and any apps that rely on it. You'll end up needing to DDU for real anyway, so you did double the work.

if you notice anything broken, try reinstall drivers again

I didn't use **THIS **option

this is how I did it.

1-UPDATE DRIVER
2-BROWSE MY COMPUTER FOR DRIVERS
3-LET ME PICK FROM A LIST OF AVAILABLE DRIVERS ON MY COMPUTER

[gleaming fractal]

that's still not the correct method for graphics driver installation, but fair enough

I know, but G-Sync is working, and everything seems to be working, and at the end it doesn’t matter because I’m going to reinstall windows anyway.

Also can I use DDU and have the nvidia app installed?

The default option with DDU is to remove NVIDIA App. You can opt to have it not remove it in the settings if you know what you are doing
