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.
Some games are built specifically for AMD from the ground up and have been optimized like crazy. Depends on the game and the devs mostly. And let’s not forget that if devs want it to run well on PS5 and Xbox Series x/s, then they better have good AMD optimization.
