Should I play it then or wait for more patches?
Bought day one, dabbled and shelved.
If you have a Series X then it runs 1440p+ at 60FPS (VGTech have a resolution and framerate video for it) and that's not a bad way to play. The biggest thing a latch could bring would be tessellation and draw distance (and a responsive map/UI), as pop in is noticeable and things like wheat in fields will render in front of you as you move. Tessellation would also help some of the now dated looking character models and ground detail.
The other issue is the HDR update on Xbox broke the lighting in SDR (there was a topic on here about it) and that was never patched. So if you have a HDR set you're fine, although the HDR is average, but if you're playing in SDR I'd hold off to see if they fix that.
Finally, on Xbox there's a pain in the ass glitch where the difficulty sometimes changes to easy mode if you start the game from rest/suspend mode (not sure about quick resume though. I played it last on One X). This bug is fun when you're 200+ hour hardest difficulty save file swaps to easy and voids your opportunity to unlock the achievement for completing the game on hard.

If you do play the game at any point though, turn of "Points of interest" markers in the settings and swap movement to alternative controls. The controls option means Geralt turns quickly instead of having a ton of animation priority, and the POI markers litter the entire map but contain nothing but scaled loot. If you turn them off you'll still easily find them as they all have natural environmental tells like plumes of smoke or debris floating in the water, but if you leave them on you run the risk of chasing map icons for worthless content which will make it feel like an Ubisoft game. Trust me, the game has hundred of hours of amazing constant that will make you travel the entire map. Don't spend fifty hours trying to clear of a checklist of map markers like my brother only to get burnt out and never finish the game.
I'd also suggest playing on Death March difficulty if you Dark Souls. It makes you utilise their entire combat system instead of just spamming shield and attack. It starts off incredibly hard and does gate you out of a few areas early on, but it also keeps the game interesting the whole way through and eventually eases off. Any other difficulty and I find the combat feels Ike a waste of time. You can always change mid playthrough anyway.
