Hi Susahamat,
I presume that response was aimed at my comment? If so I tried replacing the .exe with the one you stated. I'm still in letterbox now at 1280 x 1024. The only difference I noticed was the windowed mode was now locked to the same resolution, although it was now borderless (as intended) it was essentially the same 1920 x 1080 size letterbox.
I use Shadow (
https://shadow.tech) and have though this possibly an issue with their service maybe (raised a ticket today and posted here also incase it's a game thing) experienced since RE2 which again seemed to suggest support for 1280 x 1024 but same results as above. Prior to that I ran Metro Exodus fine at fullscreen so i'm a bit confused now which is the culprit
Can anyone confirm, should this game support and run fullscreen 1280 x 1024 out of the box? I mean it's there as an option so one would think it should work
