PC Full Screen Issues - Force fixed using ini.

[Mo]

After running into an issue getting my native monitor resolution working in fullscreen and finding no other fix aside from "make sure you're not using frame generation" <- I wasn't at the time.

I went into %localappdata% instead
C:\Users\user\AppData\Local\Marvel\Saved\Config\Windows\GameUserSettings.ini

Under this portion of the ini. set the >> settings to your native resolution and make sure any fullscreen indicators are set to 1 for true fullscreen.

Save changes.
Launch game.

This fixed it for me. No more full screen borderless window garbage.
Runs right, nice and tight.

Wanted to share because I had not seen this offered as a solution to anyone having similar issues yet.

In a context of DX12/DXGI not supporting and not having true FSE, what does this mean exactly ?

In UE5 borderless should run nativelly at the correct resolution, have you had some troubles with it ?

Borderless Windowed was acting odd in spite of my rather beefy system specs, wanted to run it full screen native as I do all my other games.

When I tried to run the game fullscreen I could not choose my native screen resolution (5120x2160).

There were several I could choose from but not the max native resolution shown above.

All of the fixes I could find cited to disable frame generation, as that was what locked people out of true full screen, in my situation I wasn't using it, so that fix was not applicable.

I could not find another fix anywhere I looked that addressed the issue of me being able to use true full screen mode with my native resolution.

Manually forcing the desired resolution/fullscreen option in the ini file worked for me.
