According to AMD, bringing fsr4.1 to pre-rdna4 must be done on a case by case basis to ensure quality standards are met.

Has anyone done extensive testing of OptiScaler of various older rdna cards and apus? To see just how big of an improvement there?

If such a database was compiled we would know the answer then, worth the effort or not. Because right now, seems a whole bunch of he said vs she said, not evidence based.

Optiscaler upscaling should be explored and tested more. If I may make a suggestion, it'd be nice if this site started.

Don't need to test everything. Just the main handheld apus would be enough. (Deck, Z1 extreme 780m, z2 extreme 890m and halo 8060s)

Of course they would have to bring it RDNA 3.5 users. With rising costs on hardware.

It's no brainer to show they're thinking of the costumer.

Besides fsr 4.1 would benefit in that hardware alone.

So many costumers will be pissed if they didn't

It was always about 'no final decision', not cancelment.

Well, Rejoicing too soon: Turns out despite RDNA3.5 APUs being the same or newer architecture, they may still not get FSR 4.1 support. This is really weird, because APUs would profit from upscaling the most. And of course, since it's the same arch, no support means artificial limitation. Unbelievable..

Can't wait for NVIDIA N1 128-bit APU (like these APUs are), or the 256-bit N1X/Spark one (Spark = Strix Halo alternative, but with DLSS support, no artificial limitation, unlike what AMD does), where DLSS latest version upscaling is supported also on older architectures (en.wikipedia.org/wiki/Deep_Learning_Super_Sampling#DLSS_4), unlike what AMD does here.

Of course FSR4 will come to RDNA3.5 APUs, because if not, it will p*** off a LOT of people and they won't feel bad buying NVIDIA anymore in the decades ahead, including me. So, why is this artificial drama even a thing.
