NVIDIA PhysX in Games [Review and Tests]

[saaya]

Err, of course PhysX means games will run slower than not utilizing it at all but what PhysX on GPU's purpose is to do this way faster than CPU would. UT3 gets over 200% performance increase with PhysX enabled on GPU on the PhysX enabled maps, a matter of playable and not playable scenario's on 95%+ of computers.

yeah but what these guys are saying is, adding a physix card and enabling physix means you get more fps than with physix disabled!

now lets say its a typo and they mean physix enabled on the gtx275 vs dedicated gts250 for physix...

clive barkers jericho 20% - no big deal
cryostasis 30% - no big deal
damnation 60% - never heard of this game?
dead space 90% - this games uses havok physix so... so i have no idea what they are talking about
empire total war 25% - no big deal
ghost recon advanced warfighter 500% - sounds a bit weird and never heard of this game
kane and lynch dead men 45% - never heard of this game
lost planet colonies 5% - no big deal
mirrors edge 25% - no big deal
sacred2 fallen angel 850% - sounds a bit weird...

1.) most games with physix are second or third class games or even less
2.) even the better ones dont show a notable enhancement with physix enabled
3.) the little cool things that physix brings in those few games could be done on cpus as well (and yes, the physix cpu mode is terribly slow, but that says more about the physix cpu mode than cpu performance of physics effects )
