If you have a 5000 series card. Return it and get your money back. These cards have been nothing but pain and suffering.
Not fun, not fast, not cheap, dangerous.
Stick with the 4's. 4000 series or the upcomming FSR 4 tech from AMD. FSR4 is going to be amazeballs, right? Please say it's going to be amazeballs.

I guess it's just you and me, 4090.

Oh no, 5000 series cards will run these games at 300fps instead 400fps

So I can have PhysX in all the classic games or pay an extra $1000 to lose that and get ray tracing in DAVG and AC Shadows?
4090 just became the most valuable hold in the history of PC gaming. Entire 4000 series have really gained value the more we learn about 5000. The performance per dollar will be interesting on the next round of benchmarks. And remember that's all we're getting for years. wtf. They upgraded the 4090 and sold us the same batch of cards again, binned differently, same memory, and oh yeah, no PhsyX pal. Papa needs a Koenigsegg.

Yeah I'm feeling pretty ok with my 4080 right now. Feels completely and totally modern considering the state of everything, and Nvidia isn't giving me a reason to upgrade.

Now don't be silly
VR's high resolution scaling shows how to flex GDDR 7
Its a bigger step for VR from 4090 → 5090 than 4090 was to 3090.

Sixteen years later, a 3000 dollars 5080 will run Cryostasis worse than a 300 dollars 9800 
Gotta love the Nvidia response - "expected behaviour", as if any layman stumbling upon that random CUDA post could figure out that PhysX was killed.
There's a great list of evergreen PhysX games, but the thousand people or so who got their hands on these new cards were not going to load up fucking Borderlands 2 on priority lmao

Just to clarify: AFAIK 32 bit Physx will still work, it will just run on the CPU instead. We're talking about games from 2007 or older here.. On a modern CPU, would anyone even notice? Idk, just asking.

Depends on how well the software is implemented I suppose. If it's designed how I fear, what with it being very old, it'll be a single threaded affair that will utter cane one core on our CPUs and be utterly dogshite. Physx was design at the time for a dedicated card, so I assume any CPU software based fallback was given minimal effort.
We'll see though. Hopefully I'll be surprised.

TBF, Borderlands 2 physx is absolutely fucked and was problematic even back then. That being said, I'm pretty surprised at the legs B2 has constantly being played more than B3

Yeah I was so ready to jump on the 5070 train till the dust settled. I'm more than happy with what the 4080 is offering me!

You were ready to downgrade to a 5070? Daaaamn.

Don't buy a GPU with less memory than your current GPU!

Sure but the only perf option they added was the 5080 falling between the 4080 and 4090. There's like 8 people playing VR on their PCs in the world, not a big enough market to need its own special line of 5xxx cards

Hmm, it appears like legacy drivers for running 32-bit Physx in games older than 2007 was released by Nvidia already in 2013... And these would run Physx on the CPU instead of on the GPU.
Does it mean the new news is old news? Idk, I'm not well versed enough with the topic to understand the full extent of this, so hopefully somebody else can explain the context.

Microsoft killed 16-bit by not releasing a 32-bit version of Win11. All 32-bit apps/drivers still work fine on 64-bit Win11 and this is just nvidia dropping support for Blackwell GPUs.
It's slightly annoying but hardware PhysX has never worked well when running on the same GPU as graphics. If you really want to use that then you'll want a dedicated low-end GPU to handle it anyway. It's also been broken in many older games like BL2 for many, many years.
I was really confused, I got it mixed up with origin dropping support for 32bit windows recently.

Always sucks to lose features but the writing has been on the wall for this for awhile.
Nvidia has been dropping 32-bit CUDA support for quite awhile now. CUDA 12.0 officially removed 32-bit support back in 2022 and as of 12.2 32-bit build chains actually throw an error. (5000 series requires CUDA 12.8)
Maintaining support for 32-bit operations does require die space that isn't really well utilized by anything released in a dozen years.

Tag, you're it.
Some people are really defending Nvidia on this? Wtf?? I don't care how, not my problem but Nvidia should offer an alternative to run those effects on 50X0 cards. Full list of games affected by this [here], some great title with great effects.

The legacy physx drivers were already required to get the arkham games to work, so I'm guessing now they won't work anymore.

4090 and 4000 series were already overpriced so in no way, shape or form it's the most valuable hold in the history of gaming.

Unlikely. You could run older CUDA versions on previous cards, but 5000 series just won't work with anything older than 12.8. It's a problem for all sorts of ML workloads that don't run on 12.8 well, though these will be fixed and patched by the developers.

Lol not at all just saying how it is.

I mean, sure, it sucks to lose access to the same (or better) quality of some older games with Phys-x enabled, but at the same point you can't expect software that old to work on newer equipment the same. For reference; from the DSOGaming article: "you’ll have to rely on the CPU PhysX solution, which is similar to what AMD GPUs have been offering all these years."
So yeah, it's not a big deal to me -- the games will still run, just not as nice.

Nah, the other guy was saying it how it is (real actual value that things are being exchanged at IRL)
You're switching things around to perceived value/feelings
On a literal level it probably might really be the most valuable hold in gaming.

oof. Thank you all beta testers.
Hope Nvidia patches things back.

Almost guaranteed this won't happen. It's disappeared from their tool chain for years now. Now if someone could hack CUDA 11.8 libraries to run on the 5090 then it would be viable, but I suspect that is very hard if not impossible. Edit: to add, they may in fact just be missing hardware to do 32-bit CUDA

We have to expect it, but it's a ding against back/forward compatibility in PC gaming.
Yes, it's still a huge benefit. Yes, PC is riddled with small landmines like this anyway. I got the message when my new system wouldn't run MS Entertainment Pack games millennia ago, and then again when many old games required either setting up a XP system or being updated on Steam/GOG. So if you care about slips through cracks, keep hardware. Nothing has really changed.

I recently replayed Arkham Asylum and the Physx effects are still very impressive. There's one scene where you're walking down a hallway in a dream sequence and hundreds of tiles are flying out of the walls as you pass them. It's a shame they didn't run with this technology more.

When even DOS games still work, yes, we can expect games with PhysX work too.

I saw the list of games affected and there are about three favorite games of mine in there. Games that i regularly play from time to time. Seems more games are affected than i was expecting.
Legacy support is important. It's the reason i wasn't interested in the Intel GPUs. Backwards compatibility is one of the things i treasure in PC gaming. Fuck these downgrades.
