The Switch 2 handles HDR at the system level - I haven't seen anything yet that has in-game HDR settings and the Switch 1 didn't have HDR at all.
You should make sure in the system options that HDR is set to run on compatible titles only, then it won't be trying to force it for games that don't support it.
If you're playing handheld then there's nothing more to be done. If you're on a TV then you will need to set your brightness etc in the system options, annoyingly the Switch 2 loves to reset these when it does system updates so occasionally you'll think "fuck, that's bright" and have to go in and turn it back down again but in general I think its support is really good.
Great shout on XCOM 2, I also have it on Switch but it ran so badly that I never really played it. Haven’t tried it on Switch 2, I will have to give it a go.
We're still at the stage in the Switch 2 lifecycle where most of the really good games are things that are available on other platforms. So people that only own a Switch 2 and are now playing Cyberpunk, Star Wars Outlaws, Hitman, FF7 Remake etc are having a fantastic time. The rest of us are still getting drip-fed new stuff slowly and it's a bit more variable.
General review of stuff I've played on mine:
Mario Kart World - better than people say but desperately needs more content
Tears of the Kingdom - LOVED IT and barely touched the crafting stuff at all
Hyrule Warriors Age of Whatever The New One Is - really fun for a bit then got super repetitive, like all these things
Donkey Kong Bananza - didn't like it
Pokemon Pokopia - really enjoyed it but people who love building/crafting games will get a lot more out of it
Super Mario Galaxy 1 & 2 - really nice re-release and the controls work way better than I expected (can't see it being as good in handheld, sadly)
I've played on the NSO emulators quite a bit too and with the original controllers and CRT filters they're a surprisingly decent way of playing old games.
Star Fox this week, at least.
I was literally in Japan last summer and nothing about Forza Horizon 6 reminds me of Japan. The fact it's full of twatty American influencers doesn't help. The main NPC in this has the same name as my wife and the fact it keeps barking my name makes it like Nagging Simulator 2026.
The only advantage it has is it's not like the previous game where I kept seeing my mate driving around for months after he'd died of testicular cancer.
The main problem as always is that Microsoft the parent company knows nothing about what the Xbox division does and just wants to know how much money it makes.
They see Halo, Gears and Forza making money and assume the solution is to make more Halo, Gears and Forza. All the other things that build a platform people actually want to own are just unprofitable distractions to the people at the top.
I really thought the new Xbox CEO was making the right noises recently but it feels she’s just been steamrolled by the money men here.
