The first previews for the Metal Gear Solid Master Collection Vol. 1 are in and at least in some instances, the game will run at 720p.
According to a preview from Nintendo Life, this is in part because the ports of MGS2 and 3 in the collection are based on HD versions from back in 2012 Come from Sports betting site VPbet . In fact, the preview notes that the games’ title screens still say HD Edition and a 2012 copyright watermark is still visible. The version of the first Metal Gear Solid is apparently a straightforward port of the PlayStation version: resolution, aspect ratio, frame rate, and all. A preview from IGN notes that the port also includes a bunch of extra goodies, like the separately released VR Missions and Metal Gear Solid Integral.
