Patch Re-Enables PhysX When ATI Card Is Present

An anonymous reader points us to a forum posting with the inevitable followup to NVIDIA's crippling of PhysX for users of any other display adapter. "Windows 7 allows two display drivers to be used at once — like in Windows XP. Therefore, it is possible to use an NVIDIA card for PhysX and ATI card for graphics rendering. Sadly, since the release of 186 graphics drivers, NVIDIA has decided to block this feature anytime a Non-NVIDIA GPU is present in the system. In addition, for some incomprehensible reasons, the latest version of PhysX System Software also prevents PPU cards from working if a Non-NVIDIA GPU is present. ... A forum member by the name of GenL has released an experimental beta patch [that] intercepts disable-PhysX-if-Radeon-is-present-code. So far, according to user comments the patch delivers successful results." The forum post has a link to the patch for Windows 7.

      Yeah, like what if your motherboard has an onboard ATI video chip are you screwed since you can't remove it?

    Greedy maybe, but incomprehensible? I think it is pretty easy to understand, they want you to go buy another nVIDIA card. I don't agree with it either, but thats just a silly word choice.

      Really? I don't see how it is difficult to understand at all. Someone decided they want to try and force users to go all NVIDIA. I don't agree with it, but I can see how some suit would think it is a great idea.

      As the ingenuity of GenL shows, it's not up to them. No matter what a company comes up with to try to get things to go their way, there is someone out there equally as smart and creative (if not more) that will break it.

  3. Nvidia should make a sensible compromise by ShooterNeo · · Score: 4, Insightful

    Why don't they just put an option to disable this check in a configuration file, with a comment above it that says : UNSUPPORTED FEATURE, ENABLE AT OWN RISK. It would cost a negligible amount of programmer time (I assume there will be people reading this comment that could write in this feature in under 10 minutes)and it could HELP nvidia. If it's possible to get more value out of Nvidia products, even if you also have a competitor's card in your machine, you are going to increase sales for nvidia products in the long run. Furthermore, if the effective install base for PhysX is larger, there's a greater chance that it will become a standard.

    Playing devils advocate here I can sort of see Nvidia's beef. Their attitude to features and drivers is quite progressive and starts back with the old TNT32 when competing with voodoo. IMHO, we now have a similar situation where ATI is making good performing card at cheap prices yet are not maintaining the robust driver feature set of NVidia. If a game is having a few glitches with shadows, chances are its with an ATI card. NVidia's point of difference are their drivers, and I can at least see engineers being a bit miffed.

    If they honestly believed that ATI made inferior video hardware, they would feel no need to deliberately sabotage interoperability like this. That's especially true when merely a warning along the lines of "this feature works best with 100% nVidia hardware" would have been sufficient. No, this kind of deliberate and underhanded bullshit is the action of a company that has no confidence in its ability to compete in an open market on a level playing field. Personally I like nVidia's products and I am not eager to see another lawsuit in an already-litigious society. However, I hope they do get sued over this (by either their customers or the government) and I hope they lose big. This kind of shit needs to be made as expensive and unprofitable as possible.

    I'm sick of those mouth-breathers standing in the way of good engineering.

    Where could the world be if those slimy bastards wouldn't be holding back the bright people?

    They do not necessarily believe that ATI makes inferior hardware, they believe that ATI makes inferior software.
