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

Can't wait for NVIDIA N1 128-bit APU (like these APUs are) (or the 256-bit N1X/Spark one), 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.

Hope it's true. Having an apu with no official fsr4 support would be perfect for me.
Whoever can give me a SoC with no modern hardware based ml upscaling in 2026, I'm getting. Don't care about price.

Meh.. it's the one thing I wish they would disable in hardware if possible. :/
I'm still upset it's possible to hack together.dll files to get optiscaler to work, tbh.
