As long as it performs fine without having to resort to upscalers, I don’t care which ones the game offers and which ones it doesn’t.
Sure, if it runs properly without upscalers that’s great, but that doesn’t mean it should be released without them either. DLSS/XESS are very easily implemented, they aren’t because AMD is preventing it.
That’s very likely (and sadly) the reason, yeah.
FSR2 is kind of the most important upscaler to me though, as it works on the Steam Deck where it’s likely desperately needed, and while XeSS technically works on the Steam Deck, the (negative) performance impact of FSR2 is way lower.
It’s also always nice to see all upscalers in the same game just so we can compare them in their most up-to-date versions.
Boy it sure sucks when it happens to Nvidia users but it’s perfectly fine when the game only includes DLSS which only runs on Nvidia cards, amirite?
