Is there an uncompressed capture showing the 720p output? Since Alex at DF thinks the difference is due to video compression.@Team Andromeda can't have your cake and eat it to.
Your premise is that Halo Infinite is full 4k at 60fps stable. People showed you that your premise is incorrect by accurately proving the game has 720p downscaling occurring in some scenes. This is VRS at work, nothing more, nothing else.
