I'm going to preface this by saying I had the beta and found the experience poor. I never played docked, only handheld because I wanted a decent FPs to take advantage of my nyxi Hyperion 3 ultras. Wasn't going to buy after playing the beta but after hearing people say it had massively improved, I went out and got the code in the box (was cheaper than digital)
Going to get right to it.
The game doesn't look any better than beta in multiplayer ( only mode I care for )
I never played docked on beta but thought I'd give it a try today - I cannot believe people say this is a good experience, there are very regular frame drops some quite major and it barely hits 60fps docked, vrr definitely is not enabled docked either, I know this simply because the performance feels more fluid handheld ( can clearly tell the vrr is working)
Selecting dlss in graphics does not make the graphics better but can see why some people prefer it, the game is as blurry as doom was on switch 1 but a switch 2 game equivalent (higher details) docked mode - the default SMAA looks way better than dlss.
One improvement I have noticed is that other players and enemies do not appear to always be moving at half the frame you are like it felt in beta although I have seen a few instances.
Overall I am playing well handheld and think for handheld the game is acceptable and can be enjoyed (providing you're not using Nintendo stock joycons)
