Using a 8400gs as a dedicated Physx card???

hi guys, me again
as explained before, I own an xfx hd 6950 2Gb dual fan gpu, which I'm using as the main GPU; now, I also found my oldie evga e-geforce 8400gs 512 Mb somewhere in my house. I was wondering, as my MoBo supports up to 3 PCI-e 2.0 cards, would it be possible that I can use my old geforce as a dedicated Physx card? I really want to play some games with the damn Physx stuff enabled, and, as you know, AMd suckts in that matter (not their fault, those nVidia guys are a bunch of pricks). Do you think my geforce will do the job?

  1. Unfortunately you can't do that, the PhysX processor won't work if it detects an ATI card.

    uhm, that's a bummer, I had heard that's possible, read about it in a lot of other forums. Are you completely sure?

    also, somebody told me that nVidia was about to unlock the physx engine to be freely used whether by AMD or any other graphics card. is that remotely possible?
  3. no way don't do it with discrepant brands.
  4. Are you actually playing any games that use PhysX?

    well, GRID, Mafia II, metro 2033, I don't remember if Clive barker's jericho uses physx as well..
  6. but you can't do it with ati.

    doesn't matter if you can it or not the 8400gs is a horrible card to use for PhysX.

    the absolute minimum would be a gtx260 or 550ti . . .
  8. there used to be a way to do it, maybe there still is. However, somebody ran benchmarks and it showed that a 550ti or better was needed to make it worth while. Anything less and performance lagged.

    Technically it is possible, but you'll need and Nvidia card as a main one, install the secondary one, download some sort of hack, do some shimmy-shammy in the BIOS, install the ATI card(s) and only then will it PROBABLY work.

    At least that's what I've heard.
  10. I've seen stories of customs drivers that support the use of ATI/AMD as a main card /w a physx card... but again it could be a myth...

    not sure what i'm really missing out on by using AMD/ATI in the way of physx...

    Depending on the resolution, i disagree, if you're at 1920x1080 then of course, but at lower resolutions a 9600gt should be enough, even the 9400 might be able to scrape by

    now please explain how resolution is a factor? (and let's cite the sources please) actually if your running lower resolutions, why run PhysX at all?

    oh oops you're right, and for running physx at lower resolutions, everyone has their own preferences right?

  15. Actually everyone on this forum has no idea what they are talking about.

    YOU CAN USE YOUR ATI AND NVIDIA CARD AT THE SAME TIME. I AM DOING IT NOW.

    SAPPHIRE 6950 WITH MY SHADERS UNLOCKED
    XFX 8800GT XXX EDITION FOR PHYSX.

    PLUS IM RUNNING 6 MONITORS... 3 MONITORS ON MY ATI CARD, 2 MONITORS ON MY 8800GT AND 1 MONITOR ON MY ONBOARD INTEL HD4000.

    I AM ACTUALLY RUNNING EYEFINITY WITH PHYSX :bounce: :pt1cable: :love:

    BF1942, BF2, BF3, WARFACE (RUSSIAN VERSION) IM ENGLISH BY THE WAY I HAVE NO ISSUES PLAYING ANY GAMES.

    IN ORDER TO DO IT THERE IS A MOD SEARCH FOR IT BY (GENL) LOOK FOR (ATI NVIDIA PHYSX HYBRID MOD 1.05FF)

    *INSTALL THE LATEST ATI DRIVERS
    *INSTALL NVIDIA DRIVERS - DO NOT REBOOT
    *RUN THE MOD
    *REBOOT
    *MAY HAVE TO ATTACH A MONITOR TO YOUR NVIDIA CARD OR GO INTO PROPERTIES AND SET IT AS A FAKE DISPLAY.....
    THAT IS ALL AND PHYSX IS WORKING WITH ATI AS YOUR PRIMARY AND NVIDIA AS DEDICATED PHYSX.

    WITH SOME OF THE NEWER DRIVERS DO NOT WORK BUT THE MOD WEBSITE TELLS YOU WHAT DRIVERS TO USE. OLDER DRIVERS GIVE YOU THE PHYSX CHECK BOX IN THE NVIDIA CONTROL PANEL WHILE NEWER DRIVERS THERE IS NO MENU OPTION BUT PHYSX IS JUST ENABLED WHEN YOU GO TO GAME AND ALL THAT GOOD STUFF. I DO NOT CARE ABOUT CHECKING ABOX AND THEN NEVER CHECKING IT AGAIN :)

    ENJOY USING ATI NVIDIA HYBRID SETUP I DO :sol:

    * Status: development is frozen. Hopefully i can continue when i find a replacement for my old broken nvidia GPU.

    * DESCRIPTION:
    This mod will enable hardware PhysX support for NVIDIA GPU, when non-NVIDIA GPU is used as a primary display device.
    - intended only for WDDM 1.1 OS (Windows 7) and NT5 WDM OS (Windows XP/2003).
    - only for multi-vendor multi-GPU configurations.

    * VERSION HISTORY:
    1.01 - 02/10/2009:
    - initial release

    1.02 - 29/11/2009:
    - added support for fixing new checks in 195.xx drivers
    - added support for XP/2003 drivers
    - both x86 and x64 are supported by a single mod now

    1.03 - 21/04/2010:
    - added support for fixing a timebomb, introduced in 196.75 and 197.xx drivers (gravity reverse + overall slowdown after a few seconds of PhysX processing)
    - mod will now attempt to patch PhysX System Software files (helps to eliminate desktop extension requirement on Windows 7)
    - mod will now disable "nvsvc" service autostart (helps to fix problems with fake displays)
    - improved patching process (no more need to reboot in Safe Mode or terminate any process)
    - improved patching logic (mod will no more try to patch non-existent files)
    - improved accuracy of some patterns to avoid unnecessary patching

    1.04ff - 29/06/2010:
    - removed support for fixing GeForce driver binaries as current 256 series don't need this (dropped support of all older 19x series drivers)
    - added support for fixing a new limitation in PhysX System Software, introduced in 9.10.0223 (aka 9.10.0528 / .0529)
    - added extra optional command line files (nvsvc and PhysX related)
    - removed most of gfx/sfx stuff (the mod is now tiny and no more requires 96dpi mode)

    1.05ff - 26/10/2011:
    - added support for fixing new limitations introduced in 285.xx drivers and PhysX System Software 9.11.0621
    - mod will now delete all application 3D settings profiles from NVIDIA Control Panel (prevents problems with known PhysX games)
    - updated old patterns

    * INSTALLATION STEPS (Windows 7):
    1. Install the needed GeForce driver 256 package. Update PhysX SS (only 9.10.0223 or later) if needed.
    2. Use the mod to patch all needed files and registry values automatically.
    3. [optional] Use command line files to set a desired configuration.

    * INSTALLATION STEPS (Windows XP/2003):
    1. Install the needed GeForce driver 256 package. Update PhysX SS (only 9.10.0223 or later) if needed.
    2. Use the mod to patch all needed files and registry values automatically.
    3. Extend the display assigned to NVIDIA GPU. Or make sure it is extended already.
    4. [optional] Use command line files to set a desired configuration.

    * NOTES:
    1. If you update PhysX System Software after using the mod, you should use it again to patch the updated PhysX files.
    2. It is safe to use the mod several times - all needed files will be patched only once.
    3. If you still have problems with fake displays and desktop extension, try to delete a fake display and create it again.
    4. To let the mod correctly patch all needed files on x64 versions of Windows XP/2003, install KB942589 hotfix first.
