Making it work with AMD cards is a more complex issue because it is a driver to a different driver issue. AMD cards have to communicate with NV cards over resources. I would imagine such allocating would be alot easier when NV knows their drivers so well and it is entirely NV hardware.

Not getting it to work on AMD hardware when it is the primary videocard is simply a matter of detecting if an AMD card is the primary videocard, a very simple task. Simply update the detection for new AMD cards and you don't have something that takes much work.

PhysX only value to Nvidia is a marketing tool and when you allow the competitors to use that exclusive feature, then you have something that is lower than worthless, as it cost money to run and you are just helping out the competition.
If there is a driver to driver issue then NV would have to state that there cards are not compatible with other makes of GPUs in the system period, & not just BS under PhysX.

The competitor is not using the exclusive feature as its not running on the competitors hardware & neither is the competitors hardware aware of PhysX running.
And if competitors wanted to play the same game as NV & your views then AMD/ATI should be doing the same & block NV cards running on AMD mobos because that would make things fair & equal.
Why should AMD invest time & money in a product that there competition can benefit from.
