It's no big secret that you can install quadro drivers onto g80 cards. Just look at cg-society.org at their maya-section. There you can find kind of a viewport problem-solution by installing quadro drivers since middle of 2007.

You can install maxtreme because it simply looks after a quadro card and if the system tells 'yeah, i got one', you can start the installation. Also viewport handling has improved a lot from max v6 to max 2008, even without maxtreme.

Also, the performance results with specviewperf are really far far away from real quadros. Ok, 12 points to 23 is a good boost, but it still can't keep up with the normal 40 points regarding the fx 4600.


By the way, why wasn't this option of 'softmodding' not possible so long? Was there an update of riva tuner necessary to get it working?


Hope I didn't irritate anyone, just wanted to make my point of view.

why dose quadro gpus cost 3x more than regular cards
lets say like this
memory on cards are better (well more bandwith than on regular cards), it have twice more ddr on it, they are optimized inside hardware to work much faster than regular card
and you say that

Ok, 12 points to 23 is a good boost, but it still can't keep up with the normal 40 points regarding the fx 4600.

yeah only ultra can do same performance as 4600 but
if you are planing to work on "lets say a grafics" you will pay 1000-2000$ for gpu like 4600 ? nah i dont think so
you would rather get high end card like 8800GTX and convert to quadro for 300-500$ so it would do the same thing but faster than regular card like GTX

By the way, why wasn't this option of 'softmodding' not possible so long? Was there an update of riva tuner necessary to get it working?

nah people just was not thinking about it
maybe because of this cpu&gpu race these days
most of reviews was trying to get info about who is making what inside industries
riva tuner haves that option after g80 card was released but no one was interested in puting it on web (well maybe because nvidia is sueing everyone who plays with their hardware and software)

Well, correct me if I'm wrong, but after reading the technical specs of both geforce 8800gtx and fx4600 i come to the conclusion, they're completely the same. So normally the modded 8800gtx should be as powerful as fx4600, not 8800 ultra as you mentioned.

And btw, their price is not that much higher because of the greater use of memory parts. The price is mostly defined by the professional, certified drivers you get for quadros.

uh you must be electronics engineer and programing guru
well if you trust that give us solid proof (like flash your gpu with quadro bios)
thank you


p.s. i was trying to tell you what goes and what do not go well you need little bit to experiment if you wanna show me something
i have tryd and i have seen fx4600 and GTX there is slight difference on pcb

Hi,
Just brought my Gigabyte Geforce 8800GT 512MB and it's G92 chipset. Unfortunally I was unable to see Nstrap tab on my RivaTuner. So can any one help me please.
Thanks

HI boonelee
when drivers are issue riva tuner wonth work corectly
how i see you are using beta drivers
reinstal driver with older series but whql ones

[Chai]

I don't think you can see Nstrap tab in Vista, right?

It is quite a learning experience reading "NVIDIA GeForce To Quadro Soft-Mod Guide Rev. 3.0". I bet it opens a door for a lot of beginners who would like to try something but dare not to in the past.

I had a problem at the early phase though:
The latest Nvidia Quadro 4600 driver pack that I downloaded has no nvdisp.inf file packed but only packed with an nv4_disp.inf file. In that file all G80 8800 series cards are not listed. Does it suggest THE END OF EMULATION OF QUADRO?

Another question:
It is not clear to me is how to identify the COMPARABLE Geforce card for its Quadro counterpart. In the example, there are multiple G80 Geforce cards such as 8800 GTX, 8800GTS, 8800 Ultra listed along side with G80 Quadro FX 5600 and 4600. How do you know which Geforce card can emulate a specific Quadro FX card without causing any h/w problem? For example, can you use any G80 Geforce card such as 8800GTS 320MB to emulate a FX4600 while these two cards have different memory bandwidths, 320-bit versus 384-bit?

Also, even if an 8800 GTS can emulate a Quadro FX 4600 without causing any h/w trouble, it can only improve D3D type 3ds Max's performance but not on OpenGL type Maya, right?

Hope these questions are not too far off...

hi dude2
what driver you wanna use ??
here is my list of moded drivers
they are working with any card
Nvidia Gforce Drivers(all gpus including mobile ones)

fx4600 is slowest from series so you can compare it with GTS cards
there is a difference in all cards but this is closest that you can get from your card
it will boost your card by few percents in Maya but also how you know that openGL based programs is best to use with AMD/ATI cards mostly because they are beter in openGL than nvidia
it is all because drivers programming nvidia dont wanna support openGL mostly because their programing sux in that section
i dont wanna play with driver cracking so we dont get any legal threats from nvidia
if you wanna drivers like that check guru3d.com they are posting all of shit like that
one more thing i think today nvidia should relise driver that supports physX on g80 cores
well it would be fun to edit this one LOL

Any card which is not as expensive but can be dual-used for gaming and preliminary drawings and animations. I just did not see the 8800s or the Geforce cards in general got listed in the official Quadro FX4600 169.96 driver pack's nv4_disp.inf file, and that alarmed me like: "Is it the end of the emulation of FX4600?"
What is the difference between the 177.xx series drivers that are posted for downloading in your referred link and the official nVidia 169.96_quadro_winxp2k WHQL driver?

Can you use any G80 Geforce card such as 8800GTS 320MB to emulate a FX4600 while these two cards have different memory bandwidths, 320-bit versus 384-bit? Or, only the 384-bit 8800 Ultra or GTX can emulate Quadro FX4600?!
How close is close enough that will not cause h/w problem?

it will boost your card by few percents in Maya but also how you know that openGL based programs is best to use with AMD/ATI cards mostly because they are beter in openGL than nvidia

I guess those Quadro specific h/w features such as OpenGL Logic Operations may be not carried over to the Geforce cards and which makes the emulation a tough task. Isn't it?
However, I am impressed to see the performance benchmark of a soft-modded 8800GTS 320MB on 3ds Max in your latest report. Does the 3ds Max performance boost come from the Quadro Maxtreme driver, or will 3ds Max's performance boost be as much impressive with Discreet's OpenGL driver? Would there really be any performance boost on Maya by this soft-mod?

BTW, do you think ATI HD3850 or HD3870 will be a better good dual-use card? How much can they match up with FireGL?

[generalRage1982hrv]

you can emulate any of g80 series to quadro

difference in those two drivers is not that small
it is all about driver optimizations right
test them both to see wich one is beter for you

i almost never playd with ati cards mostly was playing with hard mods
but never with software
