TLDR: NVIDIA removed support for PhysX with the 50 series GPUs, resulting in worse performance with PhysX games than previous GPU generations

I'm too poor to worry about this. My wife bought eggs recently

[–] [email protected] 20 points 4 months ago (1 children)

I'm so sorry you needed eggs

[–] [email protected] 2 points 4 months ago

The eggs have insane physics reactions though. So I got that going for me.

[–] [email protected] 10 points 4 months ago

So you had an egg in these trying times, did you?

[–] [email protected] 7 points 4 months ago

My wife had to start laying her own.

Guess I'll have to dust off my old dedicated PhysX card from the mid 2000's. Shit... I think that thing is AGP not even PCIE 🤔

[–] [email protected] 41 points 4 months ago

PhysX cards were PCI. Motherboards only had one AGP slot and that was for the GPU.

Wow. I probably have played 4 or 5 on that entire list. And none of them in the past 5 or so years.

It's still a shitty thing to do for sure. Maybe there will be a new "thing" that starts getting used instead? Ray tracing has gotten way more coverage than PhysX ever did, and imo is like 3% as good or interesting.

Physics actually have gameplay interactions that matter. Ray tracing looks nice, but is so absolutely expensive computationally that (imo) is not even CLOSE to being worth the effort if turning on, even with compatible hardware.

Give us better physics, games! My main time sink rn is Rocket League, and that game is literally nothing but physics. Mostly simple physics, but stuff behaving in a logical way makes my brain a lot happier than better lighting ever did.

I like when y'all grass became an actual object that could be moved around by players, or when tossing an item on the ground actually does it tossed down and colliding with other objects while texting to them appropriately (as in fire starting, or weight holding something down a certain amount). That stuff is potentially game creating, definitely feature drinking.

Has anything AT ALL been affected by "pretty lights" beyond making them pretty? If it has, I've never heard of it.

Keep games about a gameplay experience, not just a visual feast. Save that tech for movies or playable stories (ie Telltale type). Focus only on the gameplay experience otherwise. Toss in some ray tracing when you can, but NEVER at the expense of physics. It just doesn't make any sense.

I actually wasn't, no, planning to ride this 30 series out for about a decade.

Are there really any 32-bit era games that your CPU can't handle, especially if you have a $1k+ gpu? This post is honestly pretty misleading as it implies modern versions of PhysX don't work, when they actually do.

That being said, it doesn't make all that much sense as a decision, doubles are rare in most GPU code anyways (as they are very slow), NVIDIA is just being lazy and doesn't want to write the drivers for that

Well, at least you aren't on mac where 32 bit things just don't launch at all... (I think they might be playable through wine, but even in the x86 era MacOS didn't natively run any 32 bit games or software, so games like Portal 2 or TF2 for example just didn't work even though they had a MacOS version)

mirrors edge drops to under 10 fps when breaking glass which generates physx objects... with a 9800x3d.

the current physx cpu implementation is artificially shit, the cpu can easily handle it nowadays but it depends on skilled community members or nvidia themselves to unshit it.

[–] [email protected] 3 points 4 months ago* (last edited 4 months ago)

nVidia doesn't really have that many successful unshits, historically speaking, do they?

[–] [email protected] 2 points 4 months ago

Hmm, I was not aware of that. I've seen (not Nvidia related) simulations with probably tens of thousands of rigidbodies running on relatively old midrange CPUs in real time, so it's pretty crazy that it's that slow.

[–] [email protected] 2 points 4 months ago

You never know when old games just don't work. For example I recently tried to play deus ex mankind divided. I have new hardware but I had to play on medium settings because anything higher would start killing performance despite the game being 5 years older than my hardware.

I wouldn't be surprised if some older games ran like shit on the 50 series cards whenever physx is concerned.

[–] [email protected] 13 points 4 months ago

It's too bad the CPU path for PhysX is crappy. It would be a good use of the many cores/threads we have available to us these days.

[–] [email protected] 12 points 4 months ago

The more you buy the more you save

[–] [email protected] 7 points 4 months ago

Lol keep buying Nvidia!

The enshittification of green has begun

[–] [email protected] 2 points 4 months ago (1 children)

They laser off the vcpu feature from the chip just so you can't use it at the same time as another family member. They spend extra money to make it worse.

[–] [email protected] 2 points 4 months ago (1 children)
[–] [email protected] 1 points 4 months ago

They use the same silicon silicon for datacenter products Vcpu is something that allows a gpu to be used by multiple virtual machines at the same time.

They use a laser to break this part before selling it to you, so that you and your sister can't share the same card at the dame time and instead have to buy two.

My understanding is 32-bit PhysX games are broken.

64-bit compiled games are fine.

[–] [email protected] 6 points 4 months ago

No, the card is broken. Only suitable for newer games.

[–] [email protected] 5 points 4 months ago

I've had enough of NVIDIA to the point I'm not planning on playing anything on one of their GPUs ever again.

[–] [email protected] 3 points 4 months ago

Nvidia got what it wanted from Ageia when they bought PhysX, and that was improvements to CUDA.
