We're talking some time from now, mind you, not hard to see how this concept might be applied.
Yes that concept is well known now I think. AMD are working on a hybrid CPU/GPU.

Wow, didn't know that. Kind of surprised me TBH. Thanks for the info.

...Then you're dead, because the guy who blew up that crate doesn't have advanced physics hence he doesn't see the special affects that are rendering you useless.

I don't know if I explained that right but thats my opinion on it.
In other words its biased and could result in unfair gameplay. Is that what you are trying to say ?

Still HL2 Source engine is the best thing my eyes have seen. Originate from Havok 2 physics engine & highly-tuned by Valve.

The thing I like about Source is that it's coded well enough to play even on lower end hardware.

I play HL2 with details maxed on my backup rig (Athlon XP 2500+, DDR400, 9700 Pro) and still get playable frame rates for the most part. It looks just as good (if not better) IMO than Quake 4 or Doom 3.... but If I try playing one those games maxed.... my frames get so choppy I have to turn the details down.

Yes I agree. HL2 was very well coded that it was able to run on so many different machines. Even the pretty low end ones.

No doubt man, I play HL2 on some pretty crappy computers. I hear that Crysis is going to be really good on low end computers just like HL2.

Yeah I've heard of OpenRT, but it didn't seem like it really took off with the video games industry. The only thing keeping raytracing out of real time applications (like games, duh) is computing power. Just imagine a game where reflections are actually reflections! (this would take a couple hundred million individual raytracing executions per frame...ouch!)

Yep pretty much.

Kind of like in LOTR-Online where if you have a highend system like mine you can enable all the sexy flora and grass fields.

However if someone has a lower end system they can simply choose to disable those affects and for a lack of better words, can see more than I can.

Lets say I'm prone hiding in the grass waiting to snipe a guy and because he has a 7300GS he has the grass disabled and sees me out in the open and just kills me.

More eye candy isn't necessarily a good thing

Although in all fairness I can understand the concept of a dedicated PhysX card but its just too damned expensive, I'd rather spend that money upgrading my RAM or something else of that nature, maybe buy a Q6600 with a G0 stepping

But that's the whole point of controlling game variables in multiplayer, so that disabling certain things is not allowed, that way nobody would have a clear advantage.

Any decent server would do this imo.

I think one of the reasons they released PhysX cards is the developpers did not expect such a jump in performance with all the multi-core processors. I'm sure they targeted their cards for gamers with single-core CPUs, which, I believe, can benefit from these cards
