I've ended up replaying No Man's Sky Switch 2 edition because I'm shocked at how well it runs. I mentioned it earlier in the thread but I also have a Rog Ally X and that was a game I could never get to run right on that system regardless of what video settings I used. There was always an issue with FPS slowdowns if I used my jetpack which rendered the game almost unplayable.
Maybe with the Switch 2 update it will work better on the handheld PCs but I'm blown away by how well it runs. The only time I noticed serious FPS fall off was on a planet that had to render a lot of gas effects, with a lot of alien animals, and if I was sprinting/jet packing and the planet still functioned, it was just obvious the Switch 2 was struggling more than on other locations.
The graphics and smoothness isn't as high as say, a PS5 or a high end gaming PC, but the experience is way better than the original switch. I bought it when it was on sale for more than half off, and you get the Switch 2 upgrade for free if you already owned the game.
