*HowTo*: ATI + NVIDIA PhysX Guide - Page 33

post #321 of 332
Since I already have the nvidia drivers installed, Should I just set Physx Dedicated to the 580 (not auto), insert the 7970, install the AMD drivers and check if that would work?

Since you're changing the primary card I'd suggest reinstalling the drivers.
Obviously you'll want to install Driver Sweeper before doing this, I linked the download below. Also, when you first run it click on Miscellaneous under Options and un-check Create Backup. Warning: Spoiler! (Click to show)
  1. Uninstall All Nvidia Software through the Control Panel
  2. Reboot into Safe Mode
  3. Run Driver Sweeper and Clean Nvidia drivers
  4. Open Device Manager, right-click on the 580 and click Uninstall. If it asks if you want to delete the drivers for it say Yes or check the box
  5. Shutdown, remove the 580 and install the 7970
  6. Boot up. If Windows tells you to restart the computer do that first, otherwise go ahead and install the drivers for the 7970, and reboot
  7. Shutdown and insert the 580
  8. Boot up and install the drivers for the 580. After that is done, run Hybridize as Admin
  9. Reboot
  10. Install the newest Physx and run Hybridize as Admin again
That's pretty much it. No changing settings in Nvidia Control Panel or anything.
For specific games and further notes, refer to the Hybridize thread I linked. For BL2 info you can look here

Thanks a lot mate smile.gif , Both cards installed (7970 primary), managed to install both drivers and played BL2, ran 3dmark11 with no issues so far.
Gonna try the Hybridize and report back.

Thanks again mate.

Does the line contain the b in the very beginning or is it a typo? And where do I add it to?
'Upon further investigation add this line also under the [Engine.Engine] and [SystemSettings] sections, one of those is probably redundant though.
bDisablePhysXHardwareSupport=False'

Thanks again...

I did/tried everything possible but keep getting bsod when I start BL2. Also kept getting freezes in other games.
Gonna try from scratch again, but I noticed this when applying Hybridize:

This was from the link you provided for enabling Physx in BL2.....Should I do what they say in the 1st page or the steps you gave are enough?

Thanks again mate & good luck on your exams...
post #329 of 332
GPU-Z shows Physx enabled under the 7970, does it mean it worked biggrin.gif?
post #330 of 332
Select the Nvidia card in the pulldown menu of GPU-Z and go to the sensors tab. Right click on GPU usage and select max. Make sure you check the box to update GPU-Z when its in the background. Then play bl2 on high or medium physx. Check GPU-Z after.
