game resolution

Hey, can anyone tell me how to set this resolution? TY

twitch .tv/videos/137121106 (remove the space from link)

What resolution? I'm not bothered to remove spaces to check the damn link.

As mentioned above not sure what resolution you're talking about but if its for OBS (which is what Im guessing because its Twitch) then just go check out a Twitch Stream Settings OBS video.

Edit:
Checked and it turns out its for APB, should've probably asked in the APB section.
