    Meanwhile, if a game like Starfield runs better on AMD than Nvidia it's a scandal.

    Yeah because nvidia throws money right and left and makes sure the PC ports are optimized for their hardware. When an exception to the rule happens everybody screams because they are not used to amd cards outperforming their precious nvidia cards. These things can only change if amd gains market share...currently there are more ada lovelace cards than all RDNA1,2 and 3 combined in the steam hardware survey.

    This is circumstantial evidence and is about a developer supporting features of cards. This is not about AMDs direct support of cards which is what I was asking about regarding Astyanax statement.

    This is just like with GCN and DX12 - whilst GCN1 supported DX12, it only supported feature level 11_1 unlike later revisions of GCN which supported higher levels etc.

    Edit: So for clarification, we're still looking for confirmation from AMD themselves. A game developer requiring specific hardware does not confirm AMD dropping support. It only confirms that the game being developed requires newer cards.

    It's metaphisically impossible that Steam Survey is true. 2% AMD graphics??? At least this year and the past were good for Rdna2 sales in the DIY market, and RX 480 and 580 were hits.

    Yeah. With development and bring-up being increasingly expensive, they probably would hardly reach break-even point with so few sales, not to mention plenty of board/card producer brands that also need to achieve a net profit. And so far, none of them has drawn back (unlike with Nvidia).

    Yeah I suppose the actual AMD numbers are higher but I don't think there is a big conspiracy here. It just shows the steam statistics. Most likely not all users have Steam or care about it...I even have a friend that only uses battle.net to play wow and SC2 and he doesn't have a steam account...
    But there are more sources out there like JPP that have actual sales numbers and the fact is that Q1 2023 Nvidia sold 5.7 million GPUs and AMD sold 0.76 milion. It's never been that bad for AMD and I don't see how they can turn it back with RDNA3. The sales started to go down with RDNA1...gamers fell for the RTX gimmick and I don't see how they can turn this around whithout some major innovation or something that takes the spotlight away from Jensen's leather jacket. It's the sad truth. I think the only thing that keeps the GPU department alive are the consoles. If they lose that market it's game over for Radeon.

    primitive shaders and mesh shaders are actually very similar, this interview with David wang mentions that mesh shaders use the same hardware as primtive shaders on amd cards,https://www-4gamer-net.translate.go...083/?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB
    The interview also seems to confirm that primitive shaders are used on the ps5 instead, but given the former statement ,the lack of mesh shaders on ps5 doesn't really mean anything as a result.

    its also indicates the possibility that Mesh shaders could be soft emulated via primitive shaders on cards as old as vega(if hardware bugs weren't present at least). but its seems that mesh shaders are a low priority.

    also spotted this gem https://tellusim.com/mesh-shader-emulation/ , which is compute based.

    Interesting read, thanks. So if they used the PS5 primitive shaders wtf didn't they do this for RDNA1 and other gpus? I will certainty grab my popcorn when this game releases lol.
    Also it was funny seeing emulation being faster than using mesh shaders...at least on AMD.

    You seem to have a comprehension failure in this case, pixel shaders are not vertex shaders.

    Don't know that John Peddie Research, but when actual stores like Mindfactory report their sales usually AMD sells almost as much or even surpass Nvidia sales, of course in numbers, not in revenue because Nvidia cards are more expensive

    It's in the title. mesh shaders recommendations. I don't know what they used in that game and if that screenshot is relevant in this case. It was more of a joke. If you have any corrections to that screenshot you can email amd. It's taken straight from here, page 14 https://gpuopen.com/wp-content/uplo...ctX12_Ultimate_SamplerFeedbackMeshShaders.pdf

    That is just one shop located in Germany...IDK if it even ships outside Germany because their website is only in german. And for all I know the person that posts mindfactory sales on twitter can pull those numbers out of his... Anyway you can't possibly compare the sales of one shop, or one country to the global market.

    afaik amd never implemented any extensions for primitive shaders in dx12 or vulkan, they only exist presumably in the api that sony uses, and apple's metal api from what I understand, so using mesh shaders on pc makes sense.

    I see... Anyway I was wrong with my assumption that the PS5 uses mesh shaders. Can't argue with The Wang :)

    Some other stores report the same. For simple logic Nvidia can't sell that much over AMD, AMD cards are sold in almost every hardware store, if AMD sold that little, it wouldn't be offered in so much stores. I've bought ATI-AMD cards for at least twenty years without any problem.

    Nothing of importance, important games are Control, Alan Wake II and Ratchett and Clank.

    Who said anything about issues or problems buying amd cards? And who said that AMD gpus are not present in almost all hardware stores ? This is about how much they sell and in this business selling to regular users is not the big picture. You also have to take into account the corporate world sales, OEMs, businesses that sell prebuilt PCs, laptops etc. The DIY market is not as big as you think. Also those numbers that I gave are from Q1 of 2023, we are now in Q4. Maybe they picked up in sales now but how much ? We shall see next year.
