It says it only support 1080p, but the moment i open the command prompt and typed in

-borderless

it expanded the game which looks to be 4k.

How do I know it's 4k?

I use steams FPS Counter, the fps counter shrinks and scales with the amount of pixels on screen.

**After playing multiple games at 4K and using steams FPS Counter, This is HOW you play Metal Gear Rising at 4K Resolution.

Mod pin this please!!
