NVIDIA’s decision to leave PhysX behind makes perfect sense. Modern game engines now use far more powerful and efficient physics solutions, making dedicated PhysX hardware obsolete. The good news is that older games relying on PhysX could easily be updated with patches to integrate these newer alternatives, removing the need for legacy hardware. It’s time to move ondedicated physics hardware has no future.
The same can be said for ray tracing in the near future. Software-based RT is improving rapidly, and even today, some games run RT calculations on general-purpose GPU and CPU cores. As time goes on, hardware advancements like, more cores, higher memory bandwidth, wider SIMD units etc etc, will make dedicated RT cores unnecessary. It’s only a matter of time before we no longer need them. And when that day comes, I can already hear Gamers Nexus losing his minds over the NVIDIA FTX 12080 Ti not being able to enable RT in Cyberpunk

I would understand the abandonment of 32-bit driver development if the disastrous Windows finally only supported 64-bit software... But they keep releasing 32-bit software, including games. The fact that only one game supports 64-bit PhysX is alarming.
Well, let's build a retro PC with the RTX4070...
The day Proton GE translates PhysX 32-bit for ROCm on gnuLinux... Can you imagine it Then it could be done.
NVIDIA is so sneaky that it prohibits you from using PhysX if you have another GPU that's NOT from NVIDIA. The more you spend, the more you lose.
The way things are, I'm sticking with AMD and I don't plan on buying anything else from NVIDIA.
Thank goodness Nvidia Remix comes to the rescue... it magically recompiles the game so you have 64-bit physx, even if the base game didn't use it...
Nobody's talking about Havok.

I always knew physx would be dead I have stopped installing for some time now because I really dont play old games that dont have it and I dont really blame nvidia removing it. No one buys a 5090 to play old games and the people who do just need a dedicated system that plays old games end of story.. Just last year I wanted to test physx but in reality most games just suck with modern hardware its as simple as that. Same reason 3dfx didnt last long. Just like I wouldnt go buy a 4090 and then go play deux ex and expect to get 1 biillion fps lol... It just doesnt scale that way.

Dang. I mean I know 2014 games aren’t considered new, but the fact that they’re being treated as obsolete is upsetting. I mean I know trying to run games from like the 90s is kinda rough too sometimes, but I figured that was more of an OS issue and not a hardware issue. Are we just expected to only consume the newest live service triple A slop being pumped out and nothing else. I usually wait a few years after games come out now for them to iron out all the bugs. That leaves a pretty small window to play that game before it becomes obsolete

These games would perform better but nVidia in their competitiveness after buying Agea and hence the PhysX technology rewrote the CPU PhysX to execute as slowly as possible to make the GPU acceleration look even that much better. Around the same time they also got sued and lost for rewriting the accelerated card side to stop functioning if it detected anything but an nVidia GPU in the system, if you had an Agea card but were using an ATI GPU nVidia's drivers would stop your Agea card from working, classy as always.

32 bit no longer supported... that's operating systems NVIDIA, not meant to talk about a feature in a product. The rest of the game runs perfectly fine under a modern 64-bit OS, NVIDIA should have NOTHING to say about which games we can and can't play. It's seperate software package that is installed next to the driver, IT SHOULD THUS WORK SEPERATELY FROM THE DRIVER AND NOT REQUIRE HARDWARE SUPPORT, otherwise it should've been part of the driver.
I propose a new NVIDIA slogan: It just doesn't work!

FP32 CUDA can come up in science and engineering workloads. The GeForce cards have been a cheap alternative for small-time workstations, with the 4090 offering much better value than alternatives. By limiting the CUDA capabilities of GeForce, nVidia may be forcing some workstation users to get professional GPUs instead. It will surely make them more money. There's a small chance it could benefit gamers, as it would reduce the demand for gaming GPUs a bit.

If you have to buy a GPU specific to the era of game you wish to play, then you run into the same issues you run into with Consoles.
At least with consoles you have the benefit of those companies ensuring their architecture support the games available in its library.
The fact that older cards seem more capable for games made only a few generations behind current means we are being sold obsolescence as a schema, which should be concerning.

Nvidia doesn't care about SLI or PhysX any more, because they don't need to induce demand any more.
A few years ago, some gamers used to have a reason to buy 2 or 3 Nvidia GPUs, and Nvidia was happy to sell them to all of us. Today, Nvidia would rather sell 10 GPUs to a server host, and 1 GPU to a tiny minority of gamers just to remind the general public that they still make desktop hardware.

Early last year I bought an RTX 4080 Gaming X Trio for 1200 at a Dutch online retailer and I kinda regretted it but if I held onto my 2080 Ti for another year I would've been totally screwed because a decent aftermarket 5080 goes for over 1700 currently, great value for money init Especially if it includes random black screens, missing ROPs and other yet to be discovered surprises.

Hey Steev, if you liked 3D Vision I can send you my time bundle of nVidia Pre-3D vision 3D Glasses Geforce compatable card with drivers around 40 or 50. You only need to have a CRT Monitor to use them and you can enjoy some very old games with 3D glasses supported by nVidia before the new revolutionary 3D Vision. Yes Nvidia did 3D glasses twice :)

I'm very disappointed in Steve. His journalistic integrity has fallen off hard. At 26:36, he calls that display cases breaking but that's clearly ice from Penguin's ice gun that he stole from Mr. Freeze. That room of the Iceberg Lounge doesn't even have display cases! They are in an entirely separate part of the museum, shown in the scene just prior.

3:00 I'm glad that I'm not the only one noticing Wikipedia torching so many useful pages! I had 6 lists that I maintained get eliminated and nuked by people with more power. What's left is just sparse shell pages with nothing useful on them. RIP info on Athlon XP / Barton cores. RIP old CPU architecture voltage lists.

Lol like I've Always said.... just because it's old doesn't mean ya throw it away they'd have been screwed in battle ship if the navy scrapped the Missouri battleship luckily there was still enough crew around to run the darn thing with the boy's help lol but they were WW2 guys hats off to em for their dedication

Amazing video! I use a GTX 1080 Ti still so no problems here. I also own a GTX 780 and a GTX 980 Ti so i'm future proof for 32 bit physx games! I can swap one of them in and play the game then return back to my new gpu. Of course this is when i finally upgrade my GTX 1080 Ti. Great video, thank you Steve.

I literally switched from AMD to nvidia (gtx 980) because of how much better the experience was with PhysX. Ironically, I switched back to amd (XTX) after a gtx 1080 because how PhysX basically died as a feature and ray tracing is irrelevant to me so why would I say no to superior raster at a lower price

Welp looking like I'll be fabricating my own multi generational card after all thanks for all the paperweights amd& Nvidia just have to learn the coding and language for making drivers lol make 1 like my jumper cables start a big block with no battery just clamp to the terminals NO WAITING!

I have information that 9070xt from Gigabyte not work on old motherboard with 3.0 PCIe, like 2011-3(x99) platform.
Have any-one oprotynity to try it) Not on motherboart with 4.0 or 5.0 with 3.0 set in bios.
It must work on 3.0, but may-be there is situaton like with nvidia PhysX.

I managed to get selected for the verified priority access to get the RTX 5080, so of course I took the opportunity.
Then I heard about this and now I can't believe I'm going to have to install my old 1080Ti or 3080Ti as a dedicated PhysX card to get acceptable graphics in 15 year old games

If I had a higher wattage PSU my GTX 970 would be getting used as a PhysX card for my 6700XT. It's something that I did with my 650ti years ago - before I benchmarked the PhysX performance and found that the 970 was faster on its own (PCIe Gen 2 x2 probably didn't help however).
