New update just broke the Exclusive Fullscreen mode
The point is that the game now automatically switches from the actual exclusive fullscreen mode to borderless. This breaks the DLDSR I use when upscaling the game's resolution from 1080p to 1440p. I'm sure I'm not the only one using DLDSR, especially considering many players started having issues with resolution settings after this update.
The screenshot shows mode 1 in the fullscreen settings, which corresponds to the borderless setting. When this value is set to 0, the game switches it to 1 upon launch, and even Read-only doesn't help, as the file is literally recreated right before my eyes.
For players like me who use NVIDIA's DLDSR (I don't know about ADM VSR): you should set the DLDSR resolution on your desktop, launch the game, and select that resolution. This will eliminate stuttering issues and ensure the resolution is read correctly.
