u cannot break gpu phsyX without breaking cpu physX. it returns the same values from the api if u have a cpu or a gpu. im not saying that ati will never break phsyX (i dont see it happening) but if they break gpu physX it would also break cpu physX.Originally Posted by Katanai
physX is just a marketing tool to sell cards, as such they cannot let ati use any of thier proprietary features or else it defeats the purpose. why would they go an kill cpu performance unless they wanted exclusive visual features on their hardware only. i know its played out but look at batmanAA, u have a hack that took some1 2 weeks to make that enables multi threaded cpu phsyX so there is no way that the devs would have not done it if they were allowed to, then if u look through the drivers if u start with the 1st NV drivers that were still rebadged agea drivers the banners and fog worked on all physX modes and they did not effect fps then u update to the latest drivers at the time or the ones that it shipped with and all the sudden the fog is gone and the fps drop with less effects. they also changed the retail game to add the useless calculation paper floating around on all but the lowest no physX effect mode when in the demo that was the only difference from the high and mid range was that mid had everything and worked fine on the single cpu thread with all of the other effects fine and little to no fps drop with the old drivers and no GPGPU. then u have the same thing in darkest of days were they use only a few phsyX effects that are not hard on the cpu that matter for game play, but then they put leafs that float around u so u cannot do phsyX effects without having a GPGPU. i dont play many games with physX and i havnt played more recent ones like metro33 but u can see that games that used physX when it was agea always had multithreaded cpu phsyX and they focused on keeping the fluff like paper or leaves to the highest setting and in game effects were kept to a medium setting so they could sell the API and have full support for cpu only users. since NV took over agea physX its been given away to devs and i havnt seen it used in a game that was not sponsored by NV. that clearly makes it no longer a tool for physics but a marketing tool to sell GPUs.
and how is this any different from IBM dissabling features if u did not have official IBM hardware, or intel disabling features if u did not have an intel chipset, in both of those cases the features had nothing to do with the chipset or add on hardware this is the same phsyX, the unit the computes the values for the physX api has nothing to do with the api handing the values to the game engine to be rendered. for a non computer analogy it would be like saying that if u did not get gas from chevron then your car would only run at half power, or if u were running a construction site that u had to use milwaukee power tools only or you had to use only hand tools
