  • Enable PhysX tweak, anyone try it?

    At work, but curious if this actually works:

    It says you must be using GeForce’s latest 313.96 beta driver and add these to your .ini file.

    Good find Astro. I'll have to try that when I get home. Thanks for the tip.

      For the record it does work, not sure about performance or stability yet but it looks kinda cool :)

        From what I've heard AMD Radeon users can work around physix and use the cpu to calculate what is den by the gpu when having an Nvidea and using physix... anybody who knows if this applies here to?

          Well I tested it out more and performance gets rather laggy with it enabled over time, I don't think it's ready for "prime time" yet but will be a fun little addition when the performance is stable.

            What card are you using to run it on?

            Would an old 8800 do the trick?

              I am using a GTX 680, you could try the 8800 and see how it goes, are you thinking of adding the 8800 as dedicated PhysX or is that your main card? I imagine the 8800 would be having a hard enough time running PS2 as is, without the extra bandwidth if that is your main card, if it's a second let me know how that works, I'm curious.

                Nope have two 570s the 8800 would be dedicated to physx

                  I think you can do that.

                    I have a friend who did this with his old nVidia card. If I remember correctly the main GPU was a gtx260 and the PhysX card was a 8800gts. It worked well for a few days but it eventually burnt the 8800 out. This was over a year ago so mayne the drivers will prevent thus sort if thing now, just a cautionary tale for every one

                      Used it last night, nice, adds some great graphical effects including improved damage indicators, you get a better sense of making hits. I did notice some occasional frame drops but can't say whether this is due to using the beta driver or having physx enabled. My frames would drop from about 60 on max settings at 1920 by 1200 to about 30 for no discernible reason, usually around large installations where there were a lot of aircraft flying about.

                      Will say that until the fps drop 'builds up' performance overall seems better with physx enabled, perhaps because it is shifting stuff off the CPU and onto the GPU as a side effect.

                      Will test again tonight monitoring both CPU and GPU usage. A quick fix is to alt tab in and out of game and fps returns to normal. I wonder if doing that maybe flushes vram or something.

                      This is on a gtx 680 SC running at 1175 mghz.

                        The Gtx 550 Ti I have is not compatible with the beta driver...

                            Played well over 2 1/2 hrs with it on. Seems ok but did get 1 instance of lag at a bio dome which lasted maybe 5 minutes but was fine after that.

                              Yeah Hobbit, BioDome was a problem area for me too. I switched it off, perhaps I will give it another try tonight.
