Firstly, I'm talking about multiple games, not just one. Secondly, it was about RT performance. Lastly if you only play Warzone 2 then you should only care about Warzone 2 performance and happily buy an AMD card - of course!
What does equally optimised even mean? We're talking about radically different architectures particularly as it relates to how they both handle RT. It's literally impossible that they could be "equally optimised". Moreover it would be your burden to prove how exactly these are "unequally optimised" when all these games are made with consoles in mind first, which have been on AMD-only hardware for over a decade now! Not only that but EVEN IF it were true that NV dominates cause of their sponsorships rather than its superior hardware, so what? It's still AMD's problem to solve (and an AMD customer's to suffer)! Ultimately as a regular PC user you can't choose who sponsors what, only what card you buy. So it's a big fat L for AMD regardless.
Besides, I can think of AMD sponsored titles where Nvidia still dominates like Riftbreaker or Deathloop. Or should we point out how FSR 2 was also faster on Ampere than RDNA 2? Then what's the excuse, Nvidia sponsored AMD to defeat itself? Or former console-only titles where even with a mild RT implementation Nvidia is clearly superior all the same (Miles Morales). Or a title like Metro Exodus EE where it HAD to be optimised for AMD because it had to run with RT at 60 fps even on consoles (as puny as the Series S, which is essentially an RX 580 w/ DX12 features).
Just accept RDNA is crap when RT is turned on to any significant extent, no need to deny reality because you like one corpo over the other. None of them give a **** about us anyway. Let's at least not spread falsehoods.
Deathloop is not amd sponsored, it's vendor neutral, if it was amd sponsored in terms of "technical" sponsorship, it wouldn't have dlss nor reflex just like every other amd sponsored title: halo, riftbreaker, fc 6, godfall, se 5
Also, worth remembering that even though spiderman, metro ee etc. are nvidia "partnered/sponsored", the ray tracing implementation has not had any nvidia involvement i.e. it is not implemented using any of nvidias methods, cp 2077 and witcher 3 are examples where RT has been implemented with nvidias involvement, be that their development time or/and using their tools and tbf, rdna 3 does alright in them games so I don't think there is any real malicious shenanigans here.
