  • Huh? I can’t speak to “video processing”, but “NVIDIA dominance” isn’t applicable at all for AI, at least generative AI. Pretty much all frameworks for LLM either officially support AMD or have an AMD fork. And literally all image gen frameworks that I am aware of officially support AMD.

    I typically see people recommending to buy an AMD GPU over NVIDIA in AI communities…

    What AI workloads do you run?

    EDIT: Even the app in the OP only supports NVIDIA GPUs for the prepackaged flathub installation. You can run this software with an AMD GPU.




  • Nope! It actually is mathematically how it works. Upscaling does not amplify NOISE, like eg surface boiling, although it does introduce many other artifacts. Noise, specifically, would be smoothed. The problem with upscaling is actually not noise, but oversmoothing, which is why it’s paired with sharpening. You can just look at an upsampled signal to see how noise is affected. Boosting gain would increase noise; interpolating samples does not increase noise.

    You can test it yourself and see, just go ahead and disable the FSR and frame gen gimmicks entirely while keeping ray tracing on. Hell, disable all AA and motion blur while you’re at it, and really take a gander at what actual, unblurred ray tracing looks like.

    Edit: also, “with low quality upscaling” lmao I’d love to hear what the implied “high quality upscaling” does differently 😂 something right? It’s totally different!!

    They are being flamed, but it may not be what you expected. Dogpiled by MAGA accounts for not thanking Trump and daring to say something that could be perceived as negative. Lots of “MaKe ThE sHoEs In AmErIcA!!!” “This is like a small farmer IN CALIFORNIA (😱) complaining about immigration laws taking away his business!!! Deal with it!!” Twitter is a cesspool.

    I also had to scroll past a ton of pro Trump and pro MAGA bullshit that this account has been spamming for the last 8 hours straight, to get to this tweet, so they’ve learned nothing and are just trying to get back in the MAGA bots’ good graces 😂

    A true sucker






  • A huge factor is rendering resolution. I only render at most <1080p (1024x768 or 1600x1200). 2x performance improvement over 6800XT in general sounds very incorrect if the benchmarks are run at 1080p, unless they are using upscaling and frame gen to cheat the performance numbers. Do you have a link to these benchmarks? I’d be less skeptical about a significant performance improvement over 6800XT if the benchmarks were done specifically at 4k resolution though as both AMD and NVIDIA have further optimized GPUs for 4k rendering each passing generation.

    Upscaling/framegen and 4k are completely irrelevant to me, so counting that out, it is marginal improvement based on the numbers I’ve seen. I’d like to be wrong though, and I could be
