It started with me Buying Batman: Arkham Asylum, and me seeing that there was a Option for you to run the game in High Physx graphics that stated the user having a GeForce GTX260 with a Geforce GT9800 card in the macine, and I said to myself, "You cant SLI Those cards together as the series is not the same, so if thats the case then the GT9800 must become a pure Physx Card". Then i wondered if that was the case, could it become a pure Physx card while using a AMD Radeon as my Primary GPU, according to many website, Bit-Tech included as NVidia as stated, No, it cant as NVidia had disabled it, but then I found this website http://www.ngohq.com/graphic-cards/17706-hybrid-physx-mod-v1-03-v1-04ff.html which as a small Hybrid driver which re-enables the Physx on the NVidia for the PC and then the Radeon can take the calculations from it and use it for the graphics. So what I want to know is, has anyone else done this, as the Physx graphics as fully working in Batman: Arkham Asylum, and the Physx Demo Screen Saver, but no in any BenchMark Software i use, 3DMark, gives me the same score, with or without the GeForce set up to do the Physx, but Batman: Arkham Asylum, get a FPS Minimum of 31, max of 60, average of 51 with the Physx on High, and everything else on High, were without the Geforce, it was 10, 40, 22. So i want to basically Benchmark my PC and get the true scores from my PC using both GPU's 1 as a PPU.
it won't show in the benchmark software because its a hacked driver, so likely it won't use it. just be happy that its working for you where it counts, in games.
