Update for @sergih123@lemmy.world and @alehc@lemmy.ml:

Falling into the sun is a bit time comsuming and finnicky. Try to keep your speed low when you approach the surface, and keep time warp to the lowest you can bear.

The surface is at around -30 km. It looks like this:

Descending further… Long trip. As you approach the core your speed will pick up rapidly. When you’re at the core, you’ll get slingshotted out of the core at a ludicrous speed, in my case 22248.0 km/s. Interstellar travel before it’s implemented?Anyways quite satisfying flying out of the sun’s core at a fraction of the speed of light. Can recommend!

Played a little this evening. Performance is a lot better than before. Especially noticeable when launching from the launchpad. Where it froze for a second before it just chugs along smoothly now!
