Starfield is one of AMD’s biggest partner titles on PC, with Radeon cards enjoying vastly superior performance over their GeForce counterparts. All is not well with the Red Team, however. The Ryzen 7000 CPUs, including the X3Ds, are notably slower than Intel’s 13th Gen Core offerings in Starfield. Furthermore, a bug affecting only Radeon GPUs, including the RX 7000 lineup, has been discovered. If you run an AMD GPU, the game fails to render the sun (or stars, depending on your location).
Interestingly, even though the stars in certain systems aren’t rendered, the planets are still illuminated, with the light seeming to be coming out of thin air. NVIDIA GeForce RTX cards, including the older 30 series lineup, don’t suffer from this issue.
The same issue can be replicated on asteroids and planets without an atmosphere. Here, the nearby star isn’t rendered at all. However, this issue isn’t easily noticeable due to the complexity of in-game lighting, especially indirect lighting. You need to know what you’re looking for in the affected star systems to be able to pick up on this bug.
All AMD Radeon RX 6000 and 7000 series cards are affected by this bug, while GeForce cards work just fine. It’ll be interesting to see why this particular bug affects only AMD Radeon hardware and not all GPU architectures. We expect a fix in the coming days.
