NVIDIA's 32-Bit PhysX Waves Goodbye with GeForce RTX 50 Series Ending 32-Bit CUDA Software Support

Maybe some will be updated, but most will likely not...

Overall, this really won't have a impact in playing the game(s) at all

sure, you will lose the proprietary physX additions, but, tbh, they never were a game changer, which is why many AMD & Intel gamers could play the same gave just fine just with a bit less eye candy

If Nvidia really wanted to help, they would fully open source the GPU physX implementation, and then people could make wrappers that convert the physX calls to something else. Pretty much how they did it with GLide wrappers, and some other APIs as well

but, they won't since, they are Nvidia

They can't. Their GUI is based on Electron, and Google has dropped Windows versions before 10 from development.

They did, but lets be honest, because Nvidia is a dumbass and made it proprietary, we never actually got games that really were build around physics.... it was just effects (sometimes ugly as hell) that were added on top, but nothing fundamental, no game needed it to function.

I think you have mixed up which company is the “dumbass”.

Most games can run on Win 10 but some will have bugs/issues on newer OS like crashing.
Unfornuately Steam is no longer able to run on Win 7/8.1, my old rig has this error which says.
"Steam is no longer supported on your operating system."
Very irony some of the games come from that era, no workaround for this.
Unless Steam release a legacy/retro client version for older Windows so people can play retro games on older hardware.

It never stopped working for me. I probably won't be able to reinstall it if removed, and it doesn't update anymore, but...

AMD/Intel is the dumbass for not being allowed to use a technology that could have moved gaming forward?
You have to explain that logic to me.

If you still have the older Steam client version than you still be able to run it.
Unless you uninstall it than install concurrent version than it won't be able to launch.

So, can you use the older drivers then?

Upgrayedd · Thursday at 8:51 PM

Ah PhysX.. one of my favorite forgotten tech.

An interesting thing about 2nd GPUs for PhysX are not the better frame rates but the much better frame times. Running on a single card was basically as stuttery as bad SLI implementation.

I highly doubt that the NVidia drivers allow the use of two GPUs, one of them for Physx.

I mean they could but I bet they don't.

That's how 2nd GPU PhysX has always worked

Idk how to react to this, despite its flaws, I love PhysX. If you play with it enabled, you will miss it when you play without. It's like old lost tech like EAX and such. I can't play Doom3 for example without EAX it just sounds wrong. IMO the best thing to do is to build other PC with older nvidia GPU and run older driver to play those PhysX games

Some games like Doom 3 does run better on older hardware than newer one.
Especially Sound Blaster support which in modern times many games have drop support.
Which is why I still have a old Win 7 PC solely for retro but sadly Steam won't work anymore.
Probably have to find other ways to play these old games like through CD.
Haven't test EAX for so long maybe once I sought out how to access these old games.
I will try again cuz I still have a old Creative sound blaster Recon3d with EAX support.

Same here, I got Windows XP retro gaming PC to play older PC titles. Recon3D can emulate EAX but it didn't sound as good as hardware EAX mind you, last hardware EAX was X-Fi, or maybe Audigy 4.

We got off topic here, but I would retain old hardware with appropriate driver to run these games at their best IMO.

I would recommend playing Unreal 1, DeusEx1, Thief 1/2, F.E.A.R (all), Doom 3, COD 2, Descent: Freespace 1/2, etc, on Windows XP machine with EAX 3. The way those games sounded with A3D or EAX never got a match, not even with the latest 2024 AAA games. It is really sad.
