But what I'm saying is, if there was a cheap to make, stripped down graphics card they could sell and its only purpose was running PhysX it would make PhysX cheap to implement and the amount of people who could afford it would go up. Think about how many computers are sold with mediocre dedicated cards or no dedicated cards vs comps shipped with gaming quality GPU's... high end is the minority, so forking out the extra cash for PhysX isn't a viable choice for many.
And how doesn't the made up scenario not make sense? It's like Guitar Hero requiring you to use a Guitar and not allowing a controller at all. Your forced to buy the guitar extra to play the game. In order to get the most out of a PhysX title you need a PhysX capable card. So why does my made up scenario not make sense, since its essentially the same thing?
All I'm saying is that if a Game Dev forced people to buy an actual GPU from them to get all the extras of a game, people would be raging, yet when you think about it in a broader sense, thats pretty close to how PhysX is right now. Very few titles use it, but you need to spend extra cash to access it, if you don't already have a card that supports it or if the card is strong enough to use it.
I just thought a small, cheap PhysX only card, if viable, would make PhysX more available to a broader audience, and it would then make sense for game dev's to even consider it.
But as it is right now, especially if your a low end user or an AMD/ATI user, PhysX is simply not worth the money, as it is a novelty at best based on its use and requires decent hardware to utilize properly. When you compare it to similar situations as I'm doing, it just seems like a joke and an epic fail.
Just for the record, the little I do know about PhysX makes me like it for what it does, but when thinking about the situation as a whole, I think others had it right when they were saying its just marketing buzz, little else.
(and before people freak out on me stating all the benefits PhysX brings to the table, I don't mean that PhysX is junk and only useful in marketing, I just think how its implemented seals its fate as an unused wasted effort.)
