Reddit users have discovered a new bug in Starfield where the game won't render entire stars when running on an AMD Radeon GPU.
So a user on Reddit (ed: u/Yoraxx ) posted on the Starfield subreddit that there was a problem in Starfield when running the game on an AMD Radeon GPU. The issue is very simple, the game just won't render a star in any solar system when you are at the dayside of a moon or even any planetary object. The issue only occurs on AMD Radeon GPUs and users with the Radeon RX 7000 & RX 6000 GPUs are reporting the same thing.
The issue is that the dayside of any planetary body or moon needs a source of light that gets it all lit up. That source is the star and on any non-AMD GPU, you will see the star/sun in the sky box which will be illuminating light on the surface. But with AMD cards, the star/sun just isn't there while the planet/moon remains illuminated without any light source.
