This means little in the absence of 32 bit OSes. An OS running in 64 bit mode doesn't really use said "support" anyway.
No, modern 64-bit Windows still support 32-bit apps.
You don't need a 32-bit OS to run 32-bit apps.
What makes you think that modern GPUs with 5000-10000 ALUs cannot run concurrently graphics + physics?
Sorry -- ended up leaving work and didn't get a chance to respond.
Of course previously DX versions continue to work. I said discontinued and unsupported. Not completely bricked and unusable. Which is exactly what Nvidia is doing with their x32 Phys-X. Nvidia is no longer supporting it. You can continue to run this unsupported protocol using CPU processing.
Most people would rather buy a used card for that, so no, Jensen isn't getting a new jacket.
What kind of die space are you talking about?
Everything runs natively, there is no emulation involved.
Android phones are very different compared to PCs...
You have to realize that many people stick to nVidia due to PhysX too.
No -- they don't. Starting with Windows 11 - MS does not offer a x32 version of Windows. However, that said, Windows has the WOW64 bit emulator baked into windows to allow x32 software to continue to run. You don't need to do anything to get it to work, so it gives you the illusion of it running natively, but it 100% is not.
The Windows 16bit games era was short and existed before STEAM. If they did the same with 32bit right now, the vast majority of games that are currently sold on STEAM or already in people's libraries would stop functioning.
Ok? How does that change what I've said?
That's correct -- I want to be clear as well, I don't want this to happen. I would vastly prefer that everything stays backwards compatible all the time always. I'm just trying to be reasonable and pragmatic. When 90% or more of software is all written to be x64 -- there will stop being a market demand for x32 backwards compatibility, and MS will stop throwing money and resources to make sure it's compatible. It's just the nature of tech. Like I said before -- best case scenario is tech nerds much smarter than me keep it maintained and find a way to keep it going.
Try to understand what native execution (no performance penalty) means vs emulation (performance penalty).
You're comparing apples to oranges.
If they did that, it would be on purpose to push PC gamers somewhere else (consoles, cloud gaming).
The business PC market is a lot bigger than the gaming market, so I can assure you this will never happen. Tons of business people still run 32-bit apps.
My PC still runs DX7/8 games/demos. Even without DXVK, natively.
That's my point though. I don't think ending 32bit support is reasonable or pragmatic. Unless at least 90% of games/apps receive a 64bit version i don't see this happening without a massive pushback. And even that would take many years.
Fine -- emulation is the wrong word -- call it whatever you want -- but running something in a 'compatibility mode' that requires a separate set of libraries to run is not native.
Microsoft should standardize hardware-accelerated physics, I'm not sure why they haven't done it yet:
I agree - I'm not saying MS is gonna do it this year, next year, hell, in 10 years. My point is that it's still inevitable.
Make Windows/DirectX open-source and we have a deal. No need to maintain anything then. Let the community/modders maintain the codebase.
Where did I say it was? The point of the post was to show how 32-bit support is slowly being discontinued across the industry. Its not a comparison...
Woah woah woah there...stop providing context to the conversation!
Most DX7/8 games play just fine and there's also DXVK and Glide wrappers for older games.
It's not "being discontinued across the industry" as you insinuate, Intel/Windows are different and rightly so:
Then release the CUDA source code. At least the 32-bit part.
Yes, they do.
I feel like you missed my point. I never said it stopped working. I said it's discontinued and unsupported. Microsoft no longer actively supports or develops DX7/8/9, etc.
Great! If you still enjoy them then the benefit of them running on today's hardware (which they still do) should be a boon for you!
Don't believe him.
Arguing "native" T&L/shader execution in GPUs (that don't even have a stable ISA to begin with!) is a moot point. nVidia removed the T&L pipeline in GeForce 6 (GeForce FX still had it, IIRC), just because vertex shaders got fast enough to emulate T&L with better performance.
This is worse than Fermi and GeForce FX combined.
Of course it will. But not before they ensure the massive amounts of software that depends on it can still function.
You can render natively in 1080p and upscale via DLSS4 to 4K.
My brother I am emulating 20 year old console games on my PC I don't give a shit about what's currently going on in the triple A industry.
Yeah absolutely -- we're on the same page about this, I think. I'm not saying MS will just nuke it cuz it's old. They'll nuke it when there isn't any enterprise/business need for it. Gamers wanting to play 20+ year old games without the need for an emulator/virtualization of some kind isn't gonna make them lose any sleep, ya know?
I will make them lose their sleep. You can't just make half of people's libraries not functioning overnight. You can't render half of all publisher's games un-sellable.
Are ARM and Windows not big parts of the tech industry? The fact Intel even began that initiative shows that there is a push to discontinue 32-bit and there's nothing stopping them from trying again in the future.It's not "being discontinued across the industry" as you insinuate, Intel/Windows are different and rightly so:
Intel terminates x86S initiative — unilateral quest to de-bloat x86 instruction set comes to an end
A pivot here, a pivot there.www.tomshardware.com
I think you're assuming some bits I never meant;
Saying that ARM will replace x86 CPUs on PCs is like arguing Linux will replace Windows on PCs.
Why do I have the suspicion that some of you are salty AMD GPU users that never experienced the PhysX goodness and now you're having the time of your life due to schadenfreude?
MS-DOS is 80s tech and some businesses still use DOS apps (i.e. CNC).
Just for clarification...you don't give a shit about the feature being removed OR you pissed it got removed and the games you are emulating no longer work well?
We can't expect but we are not happy when they drop, even less when it is not technically necessary as the case here.
Keep in mind that's an artificial restriction imposed by Microsoft (not the x86-64 ISA), because Linux can run 16-bit programs natively via WineVDM.
Except I never said that...
Except, again, they are not discontinued and unsupported. They are still all there on both Windows APIs and VGAs drivers. Nvidia is 100% dropping/discontinuing/nonsupporting 32 bit GPU PhysX on new their VGAs.
Something that still works doesn't it mean it's not discontinued and unsupported. My 3DS is discontinued and unsupported. It still runs all the games I have -- but it's not actively being maintained and updated. I can't expect Nintendo to help me troubleshoot something if it goes wrong -- nor do I expect them to patch any flaws, problems, etc.
It is continued maintained and update. They call it DX9, DX 10, DX11, DX12... Your 3DS was "updated" to Switch but with no BC. RTX 4090 was "updated" to 5090 with all BC intact except for 32bit PhysX.
My man, entirely new versions of software does not mean that old versions are still maintained and updated. Windows 7 is dead. Unsupported and discontinued. Windows 8.1, Windows 10, and Windows 11 does not mean that Windows 7 is 'continued maintained and updated'
The latter.
