AMD

The most bizarre thing is that things like XeSS are better than FSR. There's literally no reason for intel to be able to do a better job here, especially because their solution is way newer

I have no idea what's going on on amd's software side of things, but chronic underinvestment seems to be the defining feature of the entire software space of their gpu department. Their hardware has traditionally been a lot more powerful in terms of the raw underlying compute power, they've just always done a much worse job in bringing any of it to bear

So you end up with FineWine^tm memes which might as well read "our driver department is so underfunded that we've dropped XX% of our cards performance to software issues"
