The problem is pretty much as I've stated in the topic, but let me describe it a bit more.
I've upgraded my system and replaced gfx card with brand new spanking GTX470 from Gainward, and for unknown reason can't get PhysX to work in GPU mode - so it seems.
I've got the latest drivers and the latest release of PhysX also.
Unfortunately despite PhysX showing in Nvidia control panel, with GTX470 chosen as the card to do the calculations for it - it doesn't seem to be working. In Great Kulu tech demo (and pretty much any other PhysX demo) the framerate is horrible, and in the setup I can't choose the hardware PhysX option - it's greyed out. In Arkham Asylum despite choosing the full PhysX option, I don't see the effects that should be there (papers flying around, water etc.).
I have the GTX470 connected to my screen with DVI#1, Running Windows 7 Ultimate x64, E7500 Intel Core2Duo 2,93Ghz CPU, 10GB of DDR2, P45 mobo.
I was fighting with this for a couple of days now - and I'm absolutely puzzled ... couldn't really find a similar problem anywhere.
Any ideas what to do?
I'd also like to add - I've tried uninstalling the previous drivers (yes, with Driver Sweeper in safe mode as well) - didn't help ...
Also - here are some screenshots that might be useful:
I had problems with the Control Panel on the beta 260.63 drivers. I had to roll back to the 258 WHQL drivers. Maybe you need to uninstall everything (again, sorry), and reinstall the 258 ones. It's also possible to just uninstall the PhysX driver and install a different version. Also, before you do that, are you able to set the PhysX Configuration to 'Auto'? That will automatically choose the graphics card and not the CPU. To me, unless somehow you have a faulty card, it seems like a software/driver issue.
@MattO17secs: yes, I've tried all of the above: I've been trying to uninstall (with the help of Driver Sweeper) all the drivers for GeForce I had and then install different ones ... in fact - I've gone through all the driver versions available on Nvidia's site - to no avail ... .and changing the PhysX config to "Auto" doesn't really change anything either
Use CCleaner to clean the registry, and get anything Nvidia-related out of the system and try again from the start. This is all just part of the process for diagnosing your problem. Pretty soon, we should be able to rule out a driver issue.
1) uninstalled all the drivers
2) rebooted in safe mode
3) ran CCleaner a few times
4) deleted any files or folders containing words like "ageia" and "physx"
5) deleted all registry keys containing words like "ageia" and "physx"
6) ran CCleaner again
7) installed newest drivers
8) installed newest PhysX software
and guess what ... didn't help still the same thing ... and I've still got the AGEIA panel in control panel
ahhhhhh ... ok ... I FINALLY managed to find a solution (so - I'll leave it here - just in case anyone else has the same problem) and - by god - it's so trivial I can't believe it ... apparently all it took was just deleting ONE FILE ... PhysX.cpl from C:\Windows\System32 (or SysWOW64 - in case anyone uses a x64 system) ... and that's all ... well - thanks to everyone who tried to help me (especially notty22 - you were 99% right it's just PhysX.cpl ... not ageia.cpl)
