A lot of people have been breaking AMD's cookies for years now over the lack of a true Nvidia DLSS-level upscaler, which is dependent upon on-chip hardware within a RTX GPU. So, at last, AMD squeezes the trigger on something apparently hardware-based for RDNA 4, and now some are bashing that move, on the basis of no backwards compatibility for earlier products.
Serious question: Is this somehow more egregious than telling 20 & 30-series RTX owners, "No frame-generation for you."?
I think that however poor it appeared that AMD confined their CES presentation to the CPU-side of things, it would have been absolutely foolish for them to show their cards, (pun-intended), before Nvidia revealed theirs. And, as AusWolf has noted, we still don't have all the details on the 50-series.
Personally, I think it is absolutely pathetic that, after spending high three and four-digit numbers, (dollars/euros), on a brand new, state-of-the-art graphics card with billions of cuda cores/stream processors, millions of ROPS, TMUs, and only God knows what else, we still find ourselves discussing, and sometimes arguing, about a freakin' upscaler.
Upscaling, so, you know, we can almost run a game created using some janky game engine that only five people on planet Earth have a clue how to use properly, but is still somehow becoming the game industry favorite. Or, upscaling to somewhat alleviate the absolute frame-rate blood-letting that takes place when RT kicks in. Hey, we can't live without it, right?
How the hell did we get to this point?
