And now even more performance boost after successfully patching the old Vista x64 driver for my Win7 x64, but I need ReadyDriver Plus 1.1 to disable Windows driver signing enforcement.
I haven't make an extensive test, but Maya 2009 & 3D StudioMax 2009 works like a charm 3D StudioMax even use the real "Performance Driver" provided by nVidia instead its own Direct3D or OpenGL driver.
I'm talking about almost 4x faster viewport rendering performance compare to the unmodded 8800GT and 2,5x faster than softmodded QFX3700 without the patched driver, but sadly Redway3D benchmark crashed... not that it matters...
5. Run the driver but DO NOT install it just yet or you can just extract it and move the driver to other place than the default installation folder (IT'S A MUST).
6. Because I don't know the file extension for the script, I just copy the one available in C:\Program Files (x86)\RivaTuner v2.24\PatchScripts\NVIDIA\SoftQuadro4 (any script will do) and rename it to NVSoftQuadroX (or anything you like).
7. Open the script in Notepad, erase everything and replace it with the following: ; NVSoftQuadroX patchscript by Styler - for XP 64bit Quadro softmods ; based on gellmaR (firstname.lastname@example.org) patchscript ; vista fix - ultrapregnant dog (for 182.08) ;date 07.04.2009
9. The script will ask for the location of nvlddmkm.sy_ or nvlddmkm.sys, so just point it at the driver location.
10. After finish patching the driver, uninstall nVidia driver and reboot the computer in safe mode.
11. In safe mode, run the DriverCleaner Pro and add multiple filter (nVidia + nVidia Stereo + nVidia WDM) just to be sure that all nVidia related files and registry entries will be gone. This is the reason that you MUST place the patched nVidia driver in some place other than the default location, because this utility will erase everything (files and registry) related to nVidia.
12. Reboot the computer again (normal mode) and if you have that ugly screen resolution, you have done right so far (otherwise just run step 10-11 all over again).
13. Make sure you wait a little while for Windows to finish installing the default VGA compatible driver for your display (you can check it in the device manager if the device exist, otherwise you will need to wait for it to appear).
14. Once the Windows finish installing the default driver, you can go ahead and install the patch driver and WHOILA....!!
I'm just assuming (please forgive me if I'm wrong), since you know this type of things, I mean programming and stuff like that. Is there any chance to modify this script to work on the latest quadro driver (191.78)?
Because I think the guy who originally created it didn't use Win 7 (as most of pro-application users do, they still prefer the good old 32bit WinXP due to its excellent compatibility with every major 3D apps like Pro-Eng, Catia, Solidworks, all Autodesk softwares, etc). Well, I know this for a fact since some of my friend who uses those apps in daily work, they always came back to XP soon after they try the new release of Windows (Vista/7).
Since the patched 182.08 driver is intended to work on Vista x64, on a very rare occasion there will be hiccups. I had it once, the Windows Aero theme don't display transparencies (no GPU accelaration), but after a few seconds it came back to normal.
And I don't think this driver support hardware accelated Ambient Occlusion (SSAO), which available on the new Geforce/Quadro driver and now is being used by newer games such as HawX. The performance hit on this type of games is quite big, it drops almost 10 fps or more on my rigs (new driver 40+ fps down to 30+ fps now).
But on games that don't use SSAO feature, I couldn't noticed any different at all between the new geforce/quadro driver and this patch driver, except when there's somekind of scoring/statistic involved such as fps display or games built-in benchmark.
On the good side, now 3D Mark Vantage even gain a little over 10% performance boost compare to the latest geforce driver...
On the bad side, FurMark 1.7 drops down to 10%, OpenGL Extensions Viewer don't run at all now and on Hacintosh, I think I need to update my Quictime 7.6.5 since there's somekind of lagging occur when running iTunes 9.01 or Quicktime Movie Player.
I don't currently have a windows installation (hard disks get formatted pretty regularly round here)! I would need to look at the complexity of the script. Is the guy that wrote the script not able to do it or what happens if you try applying the above to the latest driver? This is not particularly an area that I know lots about (hacking windows drivers).
I was just wondering regarding the huge performance improvements in Windows which is the opposite on the Hacintosh side (no performance gain at all, quadro = a consumer level 8800GT, which seems just a little strange to me).
Is it possible because real mac has no genuine QFX3700, instead Apple/nVidia release different series for mac (QFX 4500/4800/5600). So MacOSX uses kext that closely match the G92 GPU, which is the 8800GT kext that is also available on a real mac machine.
I bet, if somehow you can manage to use the QFX 4500/4800/5600 kext on this softmod QFX3700, there might be a real quadro performance on Hacintosh....
I have used a Real Quadro FX 4500 on OSX before and the improvement over a 7800 GTX was negligible in Maya etc. Unlike the windows drivers where teams are constantly spending time to improve the drivers and you pay top dollar for the privilege, that does not happen in OSX. I have have always been a bit suspect of OSX as a workstation from that point of view. Take a look inside your Extensions folder, for instance in Snow Leo there are only GeForce kexts, there are no separate kexts for Quadro. The Nvidia kexts that exist drive all cards inc Quadro.
Well, no wonder I get the same exact performance before and after the softmod. I've been searching the internet for quadro performance result on OSX and you have just confirmed what I had found so far.
Those who already purchase real quadro on their macpro workstation, get worst performance compare to the cheaper ATI 48xx series. But when using BootCamp, quadro really shine on all pro apps.
I guess there's only a very very small percentage of people who use pro 3d apps in mac, so apple and nvidia won't even bother developing specialized workstation driver.
Yes I have seen this before, but it is not for Snow Leopard. If you download and try installing you are told that Snow already has drivers that support this solution. I also took a look inside the package, and there are the same old GeForce drivers in there.
Hi Aqua, I dunno if I post correctly here, anyway:I own an Gigabyte 8800GT 512 and reading about your succesful mod to Quadro FX 3700 I downloaded your bios, done all modifications and flashed the card.Unfortunately i got a lot of artefacts in post .After booting the DVI signal was lost and I had to use an analog cable to see something(everything distorted and pulsing).I tried to compare your rom with mine in an hex editor and modified days after days things hoping that it will work finally.I discovered a lot of differences, so no luck I guess.I also flashed Booim's modified rom (done by you) and I had to reflash my old bios blindly.My only hope is, that you have the time to look at my original rom and see if you can make something, if can be done. Here's the link of my original rom: rapidshare.com/files/332795999/blitzkrieg_original_512.rar.html
