I believe Riky was saying it shouldn't require a patch full stop, so I presume Xbox as no such requirement. Now yes it is a system level setting (no-one said it wasn't) but given the fact they have written it may not work as advertised on unpatched games it's a rather flawed system level setting.
You I'm afraid are the one who is lacking in reading comprehension, or you are conveniently overlooking the wording in the press release. I have no experience with Xbox VRR myself so the question is does that work across all games as it should? And do games require a patch for VRR to work correctly?
As I said previously, vsync, based on evidence, can stop vrr work as expected. Lots more ps5 games are vsynced compared to xbox series x|s.
Riky was inferring vrr couldn't be enabled in every game, you know it, I know it, he knows it.
It's a system level feature end of debate.
It can be turned on in every single game.
If vrr doesn't have the desired effect in vysnced games I'd expect riky to continue explaining that vrr is not broken just like he does with Halo. These games, if my assumption is correct, will need a vrr mode patching in that removes vsync.
As you can see from ghostwires many modes, this is probably the case.
