D901c - SLI 9800 GT : PhysX framerate !

Hi all, im rly hapy with my little laptop baby and never had any prob in a few months. But recently i tried mirror s edge and cryostasis...both intensive PhysX games ! problem is everytime i see big physX effects fps drops really bad...

I can run Mirror s edge full graph in 1920*1200 without physx and everything is really fine but i soon as i activate physx i get some bad fps some times to times... same in cryostasis, when game is not really using physx i get like 80 fps and as soon as i see big effects BOOM going down to 20 or so ....

Any trick or advice ?

ps : i have latest drivers ans latest physx..

Thx all

 

define latest drivers & physx

 

Had the same problem, its not your notebook its the games crappy Physx support.
Mirror's edge doesn't like other games with that use physx-after you play another game with physx enabled , uninstall and reinstall the PhysX software (takes like 15 sec and you don't have to restart) before playing Mirror's Edge and your problems will be solved. May work with cryostasis as well but I'm not sure.

 

Do you have the latest PhysX software drivers? Which driver for your graphics cards are you using?

 

Im using the latest 185.20 drivers and the physx that go with it...with a clean install of course....

 

Did you have tried latest 179.48 official drivers with PhysX from nvidia's site?

 

An did you reinstal your PhysX before running Mirrors's Edge, or did you ignore my post alltogether

 

No change after deleting and installing physx again trying the nvidia website version now

 

Akhalani try other driver 182.05 or 182.06 this driver that you use is not soo good infact is worst driver from 180 version

 

Dox 182.05 + latest physx did the trick ! thx all for your advices

 

By the way if anyone plays crystasis and gets slow fps its just normal ! game is not optimized at all and even huge huge configs get -20 fps somtimes !
