Tom out here looking like an 80s IBM Engineer. 🤣🤭

Tom also wanted to look cool with glasses 😎

Transparencies are difficult to temporal upscale, since there’s only one set of motion vectors per pixel. Usually developers use the opaque geometry motion vectors and transparency doesn’t have motion vectors (it’s using motion vectors of the geometry behind the transparencies). FSR 3.1 doesn’t even support multiple sets of motion vectors. IIRC the other upscalers don’t support that either.

Similarly texture animation such as water surface is hard, since technically the water surface only moves up/down, while the ”visible” wave moves (along the surface). Same problem with all implicit surface techniques (distance fields and similar). Needs special effort from devs and still all they can achieve is a compromise.

I am not deeply familariar with the DLSS3 algorithm. It’s not open source like the others. But they could do AI based motion generation pass from the image to help in these cases. Kind of similar thing that HDTVs do with their pure rgb image (no motion vectors) based 120Hz image interpolation algorithms. But if you can’t get subpixel accurate accumulation, then you can’t properly reconstruct higher res image from multiple jittered low res images. It would just be blurry or blocky. Good quality motion vectors are crucial. AI based algo might be able to workaround it somehow.

Fabio's back! His last time on the show is my favorite.

people overthink things. All you need is a gpu that can play the games you like for a price you can afford. PC builder just did a poll and right now what people want in a gpu is "Most raw FPS for my budget" with eighty eight percent. Dlss has four percent and raytracing has three percent. With a minimum of fourteen thousand votes.
Raster is king and we'd buy cards that don't even support raytracing. If that gets the price down, why not make them?

[WayStedYou]

I can't believe it's not butter!

Wait that's not the same Fabio.

[gurkdoinwork]

this is a fire combo of underrated PC youtubers

[FSAPOJake]

Ancient Gameplays is always a very entertaining and informative guest.

[harveybirdmannequin]

I want Fabio to do an in depth video on the effects of upscaling and frame generation on power efficiency.

[Kapono]

Always remember, Frame Gen does NOT increase Performance.
We have to stop 🛑 saying this

Another week, another Broken Silicon EPISODE🙌🔥

RDNA3 doesn’t have separate tensor/matrix cores like CDNA3 and Nvidia do. It only has wave intrinsics (WDDM) for emitting 32 cycle optimal ALU sequence (with register routing optimizations to save power). Double ALU pipes vs RDNA2 help of course in matrix heavy workloads. It’s a big uplift over RDNA2 for AI work, but if RDNA4 is going to have CDNA3-style matrix cores, then AI perf improvement will be substantially bigger. Which likely means that AI based upscaler would not be backported.

PSSR sounds like some kind of soviet socialist republic

[christophermullins]

Just came from Fabios latest video. 2 of my favorite guys. Much appreciated to you both.

Glad to see Fabio on Moore's Law is Dead for a second time !!

[bansheezs]

I want a 7800xt with nvidia ray tracing.... at $400.... is that so much to ask?

[traildusterbt]

Fabio, you can’t use frame generation if you’re running out of vram!

[ArouzedLamp]

If Linus claims not having driver problems after x many months ago from switching to his 79XTX, AMD cards are good enough for me.

I'll switch now and then depending on what used deals are coming my way - so I have no bias

[czbrat]

It's like Alex from DF pointed out it feels like FSR doesn't do anti aliasing on moving pixels so it appears really blocky. You're looking at raw pixels. Maybe they're afraid of making it too blurry or something.

Ever since someone told me about this channel I have basically watched every single video here. Never change Tom 👌👌
