Regarding PhysX and PS2

Death2All · 2012-01-04, 09:19 PM

So we've been told that PS2 is going to utilize Nvidia PhysX to process it's physics...Or at least I'm pretty sure that's what I heard.

I'm not especially adept with this, but would an Nvidia card presumably run PhysX better than an ATI card would? Thanks.

ATI cards do not have the capability to process PhysX, they are not built to do so. You'll need a Nvidia card or let your CPU do all the work, and I wouldn't recommend that.

Also, nice flying.

you can run physx on a second nvidia card even with an ati card as primary. but i wouldn't worry about it, games have been processing physics for years on the CPU.

Not necessarily true. What determines if you can mix an ATI card and a Nvidia card is if your motherboard supports it. Just because Windows 7 lets you have two separate drivers installed does not mean you can mix card brands. This motherboard, for example, http://www.amazon.com/dp/B0033C47XI/ can mix ATI and Nvidia.

So, I'd recommend you just get a single Nvidia card unless your motherboard can support both types.

EDIT: Okay, I'll clarify; you can use two different cards by THEMSELVES on the motherboard, but if it doesn't support mixing them, you can't CrosSLI or SLIFire them. You can use the ATI for one monitor and the Nvidia for another though.

PS2 is almost certainly using the physX SDK only (somewhat similar to Havok from intel) which is currently in use by over 300 games and not the hardware accelerated version (of which less than 30 games have ever used) and so the whether your graphics card is Nvidia or ATI wont matter for PhysX in PS2.

I am still unsure what is going to be used. I just wish SOE would say which one it is for sure. If you are building now and want to use the PhysX you maybe better off going with Nvidia just in case. Probably have better over all performance due to SOE making use of Nvidia based systems too.

Running Physx natively on the CPU with an ATI card
I was thinking of giving this a try as I can't really upgrade my PC due to monetary funds and thought my 6850 could get by with this enabled for PS2.

Thoughts?

Mutant/Goku has it right. We just don't know which "PhysX" is being used. I get the feeling it's the SDK and not the graphical effects, which would make GPU brand irrelevant, but we won't know for sure until it's confirmed.

The problem is, Nvidia are...sponsoring? SOE, which means they'll probably try and steer people towards Nvidia regardless, so the only way we'll really know is once we have some benchmarks.

I'm currently running a single 5870 myself, and though it's more than a year old I don't feel like upgrading it just yet. I'm leaning more towards the dedicated PhysX GPU - come beta if I find my framerates drop whenever there's an explosion in front of me, I'd buy this: http://www.newegg.com/Product/Produc...82E16814130612 and slot that into my second PCI slot. Plus, I feel like that card will be capable of serving as the PhysX engine for a good while.

Higby stated that Nvidia will be advanced for the Physx engine.

Good for him?

PhysX runs absolutely fine on any decent CPU.
Don't worry guys, I play Arma 2.

Is that the GPU or CPU type? If its the GPU type I highly doubt its playable.

I could of sworn the devs confirmed that it is going to be the GPU accelerated type not CPU as well.

I still don't know but like I said, I'm hoping to use Beta as a tester as well. I'll make the decision to buy a dedicated PhysX card or just use an nVidia card at that point. Even in the worst-case scenario, I feel like this problem will be easily solved. The only drawback is increased power consumption, but this rig is currently scheduled for a major tuning come Holiday season 2012 anyway, so it'll be a short-term solution.
