Hey Guys!!I have a 6870 so will a GT220/240 be enough for PhysX

[newtekie1]

Yes, both will handle physx just fine. I'd shoot for the GT240 though, just to make sure for future games.

[Rakin]

or will 9600GT be bttr or GTS250 or 430 bcoz i want to keep it low a bit....

In order of raw phsyx performance:

GT220
9600GT
GT240
GT430
GTS250

However, I'd go with whichever you can find cheapest, again trying to avoid the GT220 just for futureproofing sake.

Thanx alot man!!

gtx 460 768 meg temp idle 26c under load 37c
both fans at 100%
thanks for the great write up so even i could understand and make this work

So you are using a GTX460 for PhysX? What a waste of money IMO...

[cable]

it's not a waste i had the 460 and picked the 5770 up for 65.00 just to try it out did not like now back to 460 with a 8800 GTX to run 3rd monitor no more ati thinking i'll sell the ati

I am running a HD6950 (@ HD6970) together with an 9800GTX for PhysX and that does work. nVidia's specs page also claims the GT430 to be PhysX-ready. Anyway, it's up to you. What is that GT430 gonna cost you?

Yeah, well... That's just some editing in game files you have to do. What games are the troublemakers?

[theoneandonlymrk]

gt240's sweet for physx, cheep at 50quid and can get gddr5 on it for that with no exernal power needd (all off mobo) and asa slight bonus something else to fold on 24/7 but 96 shaders is deff the min for high physx settings on games

you have to use the right driver and physx ver to get hybrid working dude and i doubt a 430 would use the older driver? ie with a gt240 i HAVE to use driver 258.69(later dont work at all) and physx9.10.0223 then update phsyx as you wish but patched after each update with physx mod 1.04ff

quick question on this, in the guide by erocker, says to use one specific driver, is it possible to use newer ones now, or is that one just widely found to be the best? thanks

I'm pretty sure newer drivers will work.

Hi guys, I have just got an HD 5870 on the cheap so I'm running that as my main card now. This means I have a GTS 450 sitting around doing nothing so I would like to do a little benching/try some games with a bit of physx action.

My question is, I only have one other PCI-e slot which is X4. Is that going to be enough bandwidth for the physx calculations? Also I have a 650w PSU, will that be enough to power my rig with the added physx card as I don't want anything blowing up on me

Thanks.

[Funtoss]

what if i have sli gtx 460 would it still handle physx?

physix just needs lower than graphic so it looks fine to put that on x4

return to what resolution you are on, the setting, the game and so
460 is pretty powerful card so if you make it sli it would be fine run graphic and physix at the same time

Awesome !! Thanks 4 the info

Hi im running a hybrid sys as described and was untill a recent fresh install using 258.62 drivers as they were the latest set i could get working but after a recent full reinstall i thought id have another go at updatein and used 270.51, and to my surprise they worked fine ish with physx mod 1.4ff, fluidmark shows hardware peing used and vantage does first cpu physx test fine using gpu to assist.

thing is the second cpu test in vantage doesnt use the gpu anymore(think its the AI one not sure but planes crashing one) ive ran fluidmark for a while and physx dosnt cut out or disable so im not sure why its not assisting in that second test any ideas?

ps woot yall 270.51 does work at least ish

ish being the word ie not, the second cpu test is the physx the first is AI and hence i was mistaken it didnt work in all games either. imho

[Blue-Tiger]

I have been running hybrid for quite a while now. At first a 8800GTX together with an HD5870, nowadays a HD6950 (flashed) combined with a 9800GTX. Running Mafia 2 is just perfect, can set the APEX PhysX on High no problem... The only this is, I keep having problems getting PhysX to run in Batman: AA. It's not a game I play that often, but hell, it's frustrating :P If you know what I've missed, let me know in this thread plz

Kudo's for the tut so far!

[Gabkicks]

i got my 6950 sitting 34th on the highest fluidmark scores Only game i know of that would be a reason to keep my 250 in my case is ARMA III, and that isnt out for another year -_-. Oh snap, i still havent beaten metro2033.

Man can you guys help me, I'm trying to do this with a 5970 and 9600gt. Everything turned out as it should be (gpuz detects physx is on,etc.) except for the fact that when i test it fluidmark. In fluidmark doesn't verify that physx is done by gpu since it says cpu > physx instead of gpu>physx and the gpu load for 9600gt sits at 0% . Man what the hell did i do wrong?

[xibeleli]

Ill just post what i posted on the other forum so you guys know what i did.

Hi guys, i have done lots of searches for this problem and asked on other forums but am still having trouble after spending 14 hours.

i am currently having trouble doing this setup (as described in title). I've installed my 5970 properly as my main display card. Now i also wanted physx support so i added a 9600gt to enable this feature. The reason im trying it is because i've heard other people having success with this.

What i did was install the drivers 275.33 drivers for the 9600gt, then the latest physx driver files. Then i simply used 1.04ff hybrid patch to allow physx to work when an ati card is present. Now checking gpuz it says Physx is enabled. I plugged a dummy adapter into the 9600gt to allow the nvidia panel to detect display and open.

However when i open up the nvidia control panel. THERE IS NO PHYSX option anywhere what so ever. Even worse when i run fluidmark, there is no load under the 9600gt meaning that it is not doing any physx processing. Only the cpu is doing it. Overall this means that the damn physx dedicated isn't doing jack.

I would really be grateful if anyone can please help me get this physx! working. After countless reinstalling and driver sweeping resulting in no difference, It's driving me insane.

Hey i have dual 460s in SLi so my question is will i get boost in benchies & physX enabled games with an 9800GT for physX?

possibly but possibly not much

and for all the last set of 100% working with mod1.04ff drivers are 258.65 Afaik they work solidly and you can still update physx, just re apply the mod each time also ive not met a game that wouldnt work with that combo of the few anyway


i am now ive looked back thru the thread gona stop repeating myself
