got metro 2033 yesturday and is awesome, but i believe it uses physx. i have an amd/ati card so i dont have the use of physx.
so what am i missing out on, and can you stick a nvidia el cheapo card in with an amd/ati card and use it for physx only?
 
too be honest with metro i barely noticed physx compared to other games the only one i ever truly thought wow... in was mafia 2. so dont threat to much its great to have but not many games utilise it too be honest.

Same here. Although I thought some of the effects in Batman:AA were quite cool too.
 
Look dont get me rong Physx looks awsome, but its a dead propriety format.

It is only included in games, which are endorsed by Nvidia. In other words, Nvidia has either given the technology to a studio or has paid the studio to use their implementation of physx.

The majority of physics in games uses open source physics implementations, such as Bullet and Havok.

Its marketing guys, pure and simple. Its a way of making the consumer think, oh if I dont have an Nvidia card I will lose out on Physx.

Its bs... Nvidia would have a far better uptake of the technology if they open sourced it, then an dev could implement it in their games for free, and then also ATI could start optimising their cards to work with it also.

Un till then, its one of those propriety things, which will never catch on, or be significant enough to be important.

It simply remains a marketing ploy.

For instance 3DMark 11 "High Temple" uses bullet physics....

Imagine the costs, or the marginalisation of the market, if they used Nvidia Physx as the physics engine......

It would break it as a benchmarking tool.

Think of the inovation and development, Physx would get if it went open source?

Got to admit, I love Phsyx, I got a NV card because it helps accelerate (thanks to CUDA) a few apps I'm using.

I love what a few games such as Batman and Metro look like with it though, the difference is small, but my friends which have seen it all agree it makes a nice addition.

I'll confess though, I do wish more titles took advantage of it.
 
yes it is possible to do with the hybrid physx mod before i sold it i ran an ati 5970 with a gtx 465 dedicated to physx. works beautifuly you need to play a lot with drivers though to fine tune it.

yeah its a shame its meant to be this great feature of nvidia but yet they fail to convince game companies to use it shame because it really is impressive.

i have been doing some reading and apparently from driver 186 onwards its not possible, and they will soon do, if they havent already, a lock down on the physx from being updated unless you use drive 186, so wouldnt be supported in new games anyway. looks like nvidia want to alienate themselves with this 'amazing' technology :(

I don't have any experience of it myself so you will have to do some reading for yourself but it looks like it is possible, however card requirements are reasonably high. Looking at the benchmarks a gtx 260 is probably the minimum you want to use as a physx card.

when theres a will theres a way they have been saying this for a year or so now they always manage to crack it just takes some time. ...... like waiting for ati drivers :D
 
lol ok will do a bit more reading what should a second hand GTX260 go for?
and do i need to do anything other than plugging it in, installing drivers and ticking a physx box or something?
 
£50 will get you this for physx:

Frankly anything more is a waste of power, heat, space and most of all money!
I use a zotac version of this for hybrid physx with a 6970. So far every game works except just cause 2 as that uses cuda bokeh filtering only in: cut-scenes and Water Simulation, which enhances the default water reflection and effects, instead of physx. Imo you don't need anything faster as the card isn't rendering gfx.

sadly i didnt get to see batman physx because i first played it on the xbox might rebuy it on pc just to see how good the physx is. :)

It adds a fair bit of debris to the Scarecrow sections I think, as well as paper and other things strewn around the floor as you move around.

I think there are some comparison videos on Youtube if you want to have a look. :)

Install the Nvidia 258.96 drivers with PhysX_9.10.0224_SystemSoftware replacing the older physx file in the 258.96 driver package. When finished then apply the PhysX-mod-1.04ff, and you are good to go!

DOWNLOAD PhysX-mod-1.04ff


Works in Batman, Metro, Mafia 2, Mirrors Edge, Dark Void, Cryostasis and Trine.
I also use it with CoreAVC and Badaboom.
 
I've got my old 8800GT on PhysX duty with my 6850 for graphics.

I wouldn't buy anything specifically - put the money towards a higher spec graphics card or CPU instead.
