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

    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)

      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.

      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.

        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.

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