Thread: PhysX on ATI

  1. #1

    PhysX on ATI

    I just registered to the forums and I have only one question.

    Is Mafia going to have nVidia-only PhysX features that doesn't work (or are disabled) on ATI graphics cards, like in Batman Arkaham Asylum?

    thought you can just use an older driver to get around this, it was an update that disabled Physx on ATI.

    No, if it's implemented like in Batman. If ATI card is present (even with nVidia), anti-aliasing for example is DISABLED. Google can tell more.

    But I'm interested that does this also apply for upcoming Mafia 2? Like that PhysX Clothing, is it for nVidia graphics cards only? And how about that AA?

    sorry dont know, nothing been said about it, only that Mafia 2 will use PhysX and PC will include some extra features, I doubt you'll get ananswer here but you could try sending a pm to someone from 2K.

    Nvidia are the owners of the Physx technology.
    ATI cards don`t support it so ATI owners won`t be able to experience that. I`m sure there will be an Anti-aliasing option which will apply to both cards.

    But isn't it stupid to implement features that are not common for all? And especially disable the features on ATI cards, even though they could be run with software. But I'm happy if they implement the PhysX features like in Risen, so that the PhysX is "invisible".

    I just wonder, why not follow DirectX (11), the tesselation would really do justice for the old rounded cars.

    But for my initial question, can you verify that there will be features that work only in nVidia cards? And what are those features? PhysX clothing?

    As far as i know, Physx is the only main feature not common in ATI and Nvidia cards.
    Physx clothing is an added advantage for nvidia owners but i doubt ATI owners will be missing much.

    Due to the higher resolutions as well as additional GPU Physx particle effects, like dynamic, interactive smoke)
    So at least so far the smoke effects and clothes. I bet that also those dynamic explosions (of the 15min gameplay video) that make the pieces of wall drop off and things fly off.

    Doesn't sound very promising, but thanks anyway.

    as far as we know all the footage to date is from the Xbox 360 version, dont think there has been any PC footage yet.

    So much for the PC being the lead platform.

    Well, I'm now playing Mafia 1 right now and even the dated graphics doesn't bother me, but it just pisses me off that I cannot see all the stuff with my newly built rig with Mafia 2. Well, I guess there is still small hope since the release isn't still on hands, but I'm getting more and more doubtful reading the forum about the game.

    I'm not writing off the PC Version, even if we haven't seen it running I do think it'll be excellent, after the horrible ps2/xbox port of Mafia 1 they probably think they have some work to do

    Actually, some PC footage has been (well maybe not purposely)shown, you can watch it here: http://www.youtube.com/watch?v=9i9mHNU5xJY (3:07) - it's not much but it's something

    Well, this time it's going to be a horrible PC port.

    Stupid to implement features that Nvidia probably paid 2K to include? Sorry man, you want PhysX buy an Nvidia card. Just because you can't use it doesn't mean that everyone shouldn't get it.

    @Darkness62: Sorry but you are wrong. DX11 Compute Shader can very well do the same as PhysX GPU acceleration and DirectX is common to ALL! But nVidia is paying to make games nVidia only, oh great. And I find it a very dirty to disable features when ATI card is present, even though if there is also nVidia card in the game.

    agree it is a dirty trick, but they are huge rivals in the market, though to some extent Darkness is right, I went with Nvidia because they have PhysX

    yup same here. I chose nvidia specifically due to Physx even though most people were pushing me to buy an ATI.
    But like i said before, ATI owners won`t be missing too much. I very much doubt there will be a marked difference in performance.

    PhysX is something not a lot people can play with. I have a Nvidia 9800GT(512) mb. I got my Phys X on max on Batman AA and it was well made inspite of the fact that i didn't feel a great difference in the graphics. But for example there is one i might say ugly looking game (Dark Void) that supports PhysX(Clothing and stuff) and i can't even turn the PhysX option on low. The game says that to play with PhysX enabled on medium you must have at least Nvidia 260 GTX and on high you must have Nvidia 260 GTX +9800 GT in SLI mode. So i guess that if you want the PhysX options enabled in mafia you must have a really good PC.

    lol What? What does DX11's Compute Shader (handles full screen motion blur and some post processing) have to do with PhysX? Mafia 2 is not Nvidia only, just the PhysX aspect is... Nvidia owns it, why give it to the competition? ATi has DX10.1 and increased performance (kind of useless now that DX11 is out, but whatever). From your posts I am not even sure you know what PhysX is, has nothing to do with which version of Direct X you use.

    Companies pay for additional content, it happens, nothing whining on a forum is going to do about it. PC and XBox 360 BioShock fans could complain all they like, Sony paid for additional content for BioShock and even Batman: Arkham Asylum why would Sony let Microsoft use it? Just to be nice to their major competitor? ROFL!!!

    Sounds like you don't know that much about PhysX GPU accelerated features. ATi has DX11 out NOW and most probably so will nVidia in this year, but DirectX is common programming API unlike PhysX which only supports nVidia graphics cards. And Compute Shader is equivalent to PhysX in means of use GPU acceleration, which is the thing about PhysX that we're talking about. With DX11 they could have done the same thing that with PhysX GPU (nVidia only feature), like those dynamic smoke and clothing, as well as lot of other things like tesselation.

    Sounds more like you don't. Once again you are talking about DX11? Why? That has nothing to do with PhysX. Like talking to a brick....

    By the way your speculative article is two years out of date. Maybe try some more recent info?

    Here's a video by Nvidia about Compute Shader, since you seem obsessed by it.

    http://www.geeks3d.com/20090403/nvid...er-demo-ocean/

    Seems ATi is using Compute Shader to enhance performance, but yet again none of this has anything to do with PhysX.
