“even UT3 is only a small radius when physics are used if you cover an entire maps physics for no reason there is inevitably going to be a performance hit even with a PPU”
It’s not no real reason. Take a nuke when it goes off you expect it to effect things more then a 2 meter radius around your foot or what every tiny size it really is in game. Physics that cover an entire maps are done in PPU games like UT, Cellfactor or Warmonger at 30fps so how can you say the PPU cannot do it? Yes there will be a performance hit with the PPU but at least it stays playable at 30fps over 1fps with the CPU.
“You said crysis was cpu limited, the very fact when playing the game my cpu isn't being maxed out surely says the opposite?”
I said its CPU limited with the extra physics turned on, not CPU limited during normal gameplay.

Another time I said
“Crysis is both CPU limited and GPU limited in certain situations. During normal gameplay its mostly only GPU limited.” Slight but very important difference to saying its CPU limited.
“I said i maxed out all the settings, so as far as the game is concerned it is running high physics”
I very clearly said in the other discussion I was talking about extra physics turned on with the ini file. In the thread I defined what I classed as high physics and explained how to turn them on. I was not talking about default in game physics. Yes runing the ingame settings on max physics is not CPU limited but that doesnt prove me wrong as I never said it would be CPU limited like that.
I don’t considering a tiny physics radius to be high physics. I don’t consider a nuke going off and trees, buildings e,c,t not being effect outside a 4 meter area as high physics. (4 meters is a guess might be a little less or more)
“Hard tweaking values is pretty irrelevant to the game as those settings would never be used in a game, i could take a PPU game add a million effects and i bet i could simulate a performance hit. In reality it is completely pointless to the game itself” which will never be used in a game, including those with a PPU”
You’re completely missing the point. It’s not irrelevant. The only reason those settings are not done in game is because the CPU is too weak and cannot handle them. Same with 3d liquids and other neat pshyics effects, the only reason we dont have them is the CPU is holding us back.
If the CPU was powerful enough we would have those effects in game. I was using those physics as an example of how the CPU is a bad choice for physics and we need something more powerful then the CPU. I was in that older discussion talking about PPU’s in general not the Ageia PPU, there is no reason why a PPU couldn’t do those physics the CPU cannot. My main point was Crysis is an example of how high end mass physics are unusable on CPU’s and PPU’s are needed to push phsyics forwards.
CPU’s are holding physics back. Extra cores are not enough for physics.
I really don't want to upgrade from a dual core to another dual core!
