What games actually use the multi-threaded SSE supported PhysX 3.0?

    Most of PhysX is still running on the CPU, it's only a few very specialised functions that are actually GPU-accelerated. I saw a list once of which functions ran on GPU vs CPU but it was a long time ago (back when they found out PhysX was still using the old deprecated x87 co-processor instructions from the 80'ies).

    This thread is so off topic...

    Is it safe to say that there isn't any games using PhysX 3.0 and its multithreaded CPU support?

    I can't think of any. Planetside 2 GPU usage is pathetically low with CPU usage pathetically low also. When I play WarFrame GPU usage is stuck at 50%, but my CPU is barely being tasked. Don't care what Nvidia or their supporters say, there is clearly a ton of things going to to make sure it runs like crap. And of course Borderlands 2 does give the option to turn on PhysX, good grief, FPS goes from 70+ to about 10-15 in some scenes featuring liquid junk physics.

    Anyone who says it's Aegia's fault, is delusional. Nvidia acquired Aegia in 2008... Give me a break, if they haven't fixed it since, then yes, nvidia intentionally wants to cripple non Nvidia systems.

    I'm really hoping when the new consoles come out, when ALL consoles will be AMD, and 2 out of 3 being x86 AMD based, developers will stop using this garbage PhysX.

    But it's great to see that THREE YEARS after Nvidia announced they would fix this ****, there still isn't a game that demonstrates anything close to what Nvidia spoke of.

    PhyX is a 25% technology and 75% some thing else made exclusively to make fun at people who do not know much about physics simulation (especially trying to do micro simulations of them in games) and at competitors.

    I am sure people have heard about PhyX software with intent slowing down micro simulations and reverse 3D space physics gravity when there is an AMD card on the same motherboard?.

    Indeed)
    I don't even want to argue, it is just hopeless.

    Yay. I see experts here :)

    Yay, i see a wiseguy here. :p


    Fyi, im speaking from personal experince in something like Warframe and The Secret world - both use physx3. Also becuase i played any HW physx game so far and i saw a certain pattern, hw physx2 is crap, physx3 aint that better either, yet. ;)


    Btw to the one about PlanetSide2, the game now supports HW physx but its nothing special - looks fake and surprisingly it runs ok by apex turbulence particles. But overall yeah it has strange bottlenecks, mostly cpu or very big gpu inside stations.

    Would be interesting to know, what elements in the game have PhysX attached to them.

    I suspect that it impacts performance but good machines should be able to maintain 70+ FPS despite this. Seems to me where PhysX has most detrimental effect is in MP games, Co-Op or PvP. I find even without a lot of particles and things going on screen, just because there is 4 players just doing something, performance drops to 30 FPS when it was running at 90 before. It's really weird.

    Fluttershy how can you say that!

    What happen with the Fluttershy everypony knows and love?

    Oh, sorry for late responce, I tought this thread was deserted =)

    No, I'm just Zogrim. From PhysXInfo.com. Heard of us?

    I really wonder how you have concluded "10-15%" performance difference from playing those games :confused:

    Anyway, we have some materials in the work (and I hope we will be able to publish them soon enough) that will investigate CPU performance differencies between various physics engines (including PhysX 2.8 - 3.x) in various cases (rigid bodies, scene queries, joints, etc) and pleminary resuts show that latest PhysX 3 is faster than 2.8 from x1.6 to x4.5 times - on a single core.

    Slightly more than you proposed. But of course, it won't make physics in PhysX games like 300% better automatically :)

    I don't care one way or another about AMD/Intel/Nvidia, other than which performs the best without taking a full mortgage payment, but its interesting to see all those that are so faithfully programmed by the propaganda :) no doubt :)
    ..and PhysX, whats that? ;)

    Yes i have cool and I apologize :nerd:


    How i pulled that number, well i compared it with min fps and minimum gpu usage, almost any HW physx2 game has this limit where it bottlenecks the gpu to ~40-50% and lowest fps ~ 35-40fps by lots of particles and stuff.. Ok the secret world isn't hw physx3 capable, but Warframe is and here i saw better lowest fps and better lowest gpu usage instead of usual min 40-50% usage now min 50-60% (same thing in Hawken and PlanetSide2), so i came to conclusion its only 10-20% faster atm.

    Edit: this is what i mean

    Fluid Sandbox
    [​IMG] [​IMG]

    Gpu usage never exceeded 40-50% unless I filled the box with full water but then it quickly returned to lower 50-60% with slow fps ~30-40fps. Cpu usage was ~ 30-50% per core, relatively multi core capable, but obviously there seems to be a bottleneck in the code.

    We have this thread for month now. And not single game was found using Multi-threaded CPU physX from SDK 3.xx.

    Month ago Planetside 2 got back it's Cuda HW support for PhysX. Now another 7.8GB update, I wonder if it will enable CPU PhysX or not.
    (And game will sit on my HDD for another month again before next disappointment.)

    Off topic: I saw that nice "tech demo" from nV regarding water simulation in very small aquarium.
    It was nice, but reason why it's small aquarium is that if you double it in each direction you get 8 times more particles to calculate... Power Hungry or Sluggish.

    Edit.: Still no CPU PhysX on PS2.
