Pure PsyX performance

Borderlands 2, Hawken, PlanetSide 2, Metro: Last Light, WarFrame

The only new game is Metro Last Light. Any more up and comer block buster AAA games set to include Physx ?

Witcher 3 and Batman Origins.

I doubt that Witcher 3 will have Physx since the first two games did not. Batman ok but that's an old series that already had the Physx branding. What about brand new games ?

When PhysX was first introduced, desired to see 6-12 titles a year -- and there was some years there were only two --- was very disappointed based on how I feel about advanced physics -- so, having 5 GPU PhysX titles offered with-in a year is a step forward to me and very welcomed.

Um because naturally nvidia will tell you to buy a 780, 690 or Titan.

But a 780 for dedicated phsyx? Sounds like overkill. I wish they could tell us which of their other cards would keep up for physx.

as I already mentioned its a moving target. it depends on the game and your main gpu so there is no way they can go through every combination. whats overkill for one game and setup may not cut it at all for another.

Well you cant count repeats that already have Physx branding such as Batman as a new Physx title. Games like Tomb Raider, BF3, BFBC2 etc have excellent Physics engines and they run great on any hardware not just nvidia. SSE vs X87 Physx I guess you have did not read up on Physx really all that much. See SSE is available on any CPU and run Physx much more efficiently than X87. nvidia has no choice but to go to the more effecient SSE code path like the rest of the industry because the Consoles cannot run X87 Physx as we all know AMD hardware exclusivity across all consoles.

so we cant count sequels or franchises that already exist? lol I love how you set up your own rules. so using those same rules we should not talk about the Battlefield games or Tomb Raider series not having physx since that are not new franchises.

How come so few new games have Physx ? Seems like a legit question does it not ?

Does any new blockbuster hits besides Metro LL even have Physx ?

I started a PhysX thread at Rage3d, which has nearly 150,000 views:

nVidia improved multi-core - multi-thread with SDK 3.0 and still improving CPU PhysX:


Multithreaded performance scaling in PhysX SDK

what difference does it make? if we list games you will find excuses and say they dont count. if it was 20 games a year you would still find something to complain about it. personally I dont care if a game has physx and neither do most people but you really dont have a point other than to complain.

OMG it's not about improving threaded performance it's about embrasing SSE like the rest of the industry because it's 100% better than x87 as indicated in the artcul you linked to. nvidia will not embrace SSE to the bitter end because they can sell more nvidia product by sticking with the crappy x87 path. nvidia got corned into embracing SSE because the new consoles all went with AMD.

So you just admitted that you got nothing to bring to the table as far as new AAA blockbuster hits that have Physx other than Batman LOL ok then cool beans.

and you just showed us that you have nothing to do but troll today. you dont want answers. all you want is to pick apart anything that anybody says and twist it. you clearly have mental problems.

SSE is used by default with SDK 3.0

SSE is used by default with SDK 3.0

So there's absolutely no X87 anymore ?

 

[SirPauly]

That's a good question! I don't know but there may be x87 flexibility for the developer to support older CPU's.

There's no x87 support when there is not nvidia hardware present.

Good Morning.

PhysX SDK is SSE enabled for like 3 years already.

PhysX SDK 2.8.4 with SSE2 was released in 2010, and PhysX SDK 3.x are all using SSE by default.

So there's absolutely no X87 anymore ?

Yes.

 

[Irishwhitey]

Yes.

So then if all Physx are CPU now then why all the hype for legacy x87 GPU accelerated hardware to run few old games.

 

[Carfax83]

that is incorrect. the faster your main gpu is then the faster your physx card has to be.

Then how was I running a GTS 250 in a 580 SLI rig all these years without issues?

an 8600gt could offload physx with a gts250 for the main card but if you used the 8600gt for physx with a gtx480 then it would way slower than letting the 480 do both graphics and physx.

If the PhysX card cannot handle the physics workload, then yeah, it's going to slow down the main GPU.

But there's no sense in pairing a 660 Ti with a GTX Titan just because the Titan is so fast and it absolutely must have the fastest PhysX card possible.

No single player PhysX game even comes close to using the computational resources of a 660 Ti, so why bother buying it?

Just get something fast enough to handle the workload so that it doesn't slow down the rendering GPU.

because you are unaware of how much better a gpu faster than the gts 250 can perform I guess. you are crazy if you think a gts250 is a decent physx card to pair with 580 sli. heck mafia 2 recommended a gtx285 or better for physx if using a single gtx480.

now again I was saying that if you can afford a Titan then get a gtx660 or better so you can get the BEST use out of having a card for physx. is that really so hard to understand? I guess so since it appears that you still dont get that the faster your main gpu is then the faster your physx card needs to be.

The first question you answered yourself. You could have easily tested it by using a single 580 (with/without physx), then a 580 with a 250 for physx, then a 580 and the second for physx. Either way, ignorance is bliss and being you didn't test it or at least don't seem to have based on your post. The 250 might be fast enough for the 580, there is a certain ratio or dependency factor and it does depend on the game. It's guaranteed to fail on BL2 4 player but then again so does everything else.

As for the 660 ti, Multiplayer?

I have the collector's edition of Mafia 2, and I played and beat that game twice; first with 480 SLI and then with 580 SLI. I used my GTS 250 for PhysX in both games, and I experienced no problems whatsoever, despite NVidia claiming I needed a GTX 285. I also played Batman Arkham City with the GTS 250 (although I overclocked it a bit) and experienced no frame rate issues.

So if you were dumb enough to use a GTX 285 for Mafia 2's PhysX, then my hats off to you..

I guess so since it appears that you still dont get that the faster your main gpu is then the faster your physx card needs to be.

I have almost every hardware accelerated PhysX title, and what you say here runs contrary to my own experience. The speed of the main GPU has absolutely no correlation with the speed of the PhysX card, since the PhysX effects are determined by SOFTWARE not hardware.

The only thing that matters is whether the PhysX card can perform the PhysX computations adequately and is not overwhelmed. If it can do that, then there should be no performance issues.

I never even considered upgrading my PhysX card until I played Metro Last Light and got into a gun battle with the Nazis (the part where the Nazi is beating the crap out of that guy and forcing him to call his mother a whore) which had a lot of destructible objects. All of the particle effects overwhelmed my GTS 250 (for the FIRST time ever) and caused the game to freeze. That's when I decided to get a GTX 460.
