John Carmack reckons PhysX is useless

Doom creator reckons that GPUs and multi-core CPUs will do good enough job anyway

Wily Ferret, 19th July 2007


Quote:
JOHN CARMACK appears to have put another nail in the coffin of dedicated physics add-in cards by suggesting that he doesn't believe they really add anything to a system that multi-core CPUs can't also do.

Speaking to BootDaily, Carmack said, "I am not a believer in dedicated PPUs. Multiple CPU cores will be much more useful in general, but when GPUs finally get reasonably fine grained context switching and scheduling, some tasks will work well there."

Carmack, like Intel, Nvidia and DAAMIT, appears to think that using GPU and CPU capacity to handle this stuff is a much better idea than requiring an extra add-in card. Indeed, upcoming Valve title Half-Life 2: Episode 2 and Crytek's Crysis both do advanced physics calculations across CPU cores, and Carmack's decision to go the same way may tip the scales.

They do have a use but no was bother to even use them has physics rendering inside there game engine because using 3rd GPU can do the physics rendering and faster depending on the card of course

I think it could go places.
It just needs a certain level of support (when you understand its intricacies).

As the article rightly said though ( I gather), More processing power can suffice..

so PhysX may never.. TRULY come to being.



I wish DX10 could work with Dx9 cards

It will go no where without the developers support

CO-creator. Sorry to take it off topic, but people tend to forget that he and Romero founded id and that they both made Doom and Wolf3D together.
