3DVagabond, in your opinion which is more practical PhysX or SLI/Crossfire
and has PhysX really made a big impact on games , is it as popular as it is made out to be, also is there that many games using PhysX
thanks for you reply
They are not an either/or. They are in no way linked. A game can have PhysX (for nVidia only) or not, independently of multi GPU support for either one or both of the brands. I'm not sure where you are coming from with this?
As far as how popular PhysX is, there are probably 2-6 games a year that support hardware accelerated PhysX on the GPU, which uses the GPU to do particle/fluid/cloth effects. I have my own personal opinion as to the value, but if you asked 10 different people you'd likely find the opinions are pretty split. Same goes with Multi GPU. While it's supported in most games and it generally supports both AMD and nVidia, if you asked 10 different people you'd find opinions as varied as, "It's the best bang for your buck performance" to "It's only worthwhile if you need more performance than what a top of the line single GPU can offer" to "I would never own multi GPU because it's too much of a hassle and never offers as smooth of an integration as single GPU does".
Personally, I would prefer if resources were spent on optimizing performance to get us closer to photo realistic rendering (the holy grail). Generally PhysX effects tend to be over done to draw attention to them. Some people really love the effects. PhysX requires more processing power than the visuals it gives you. Again, this is just my opinion.
