Starfield's "exclusive PC partner" has players worried about performance and ray tracing

gamesradar.com:

AMD has announced that it will be the "exclusive PC partner" for Starfield, and that has PC players worried that they're going to be missing out on the superior versions of upscaling and ray tracing tech available on Nvidia graphics cards.

"We've built all new technology for it with Creation Engine 2 and working with AMD on that to make it look great and run great has been really, really special," game director Todd Howard says in the announcement video. "We have AMD engineers in our code base working on FSR2 image processing and upscaling and it looks incredible. You're going to get the benefits of that obviously on your PC but also on Xbox. We're super excited and can't wait to show everybody more."

FSR2 (more properly, AMD Fidelity FX Super Resolution 2) is an AMD-developed, open source technology for upscaling game images. Basically, it's a shortcut to improve performance, where games can be run at lower internal resolutions with better frame rates, but the image you actually see on-screen will be at a sharper, higher resolution. This benefit is available in many PC games, and is used in console titles too.

The issue is that Nvidia's equivalent technology, DLSS (or Deep Learning Super Sampling), usually offers much better results, both in terms of performance and image quality, in the games that support it. Unlike FSR, however, DLSS is locked to Nvidia graphics cards because it relies on specialized chips included on that hardware. That's one of the reasons that Nvidia has taken over the vast majority of the PC GPU market.

Historically, AMD-sponsored games tend not to offer support for DLSS, and PC enthusiasts have long speculated that it's because in direct comparisons between DLSS and FSR, Nvidia's tech wins out
