So you’ve installed that brand new nVidia GeForce GTX 580 and you’re suddently getting an annoying “PHYSX > GPU” message in the top left of your PC game? Older nVidia drivers did not have this enabled by default, so upgrading your drivers (or even migrating from ATI cards) could give you this message. This setting is enabled automatically when you install newer nVidia drivers, and is very easy to disable. You just have to know where to look.
First you need to open up the nVidia Control Panel
Right-click anywhere on your desktop and select “nVidia Control Panel”. If you don’t see this option in the default context menu in Windows 7, then you need to follow the next steps:
How to open the nVidia Control Panel (the long way)
Now that the NVIDIA control panel is up, look at the top “File” menu. Make sure you can see a “3D Settings” menu item.
If you don’t see a “3D Settings” top menu item:
Now you can turn off the Physx > GPU message in all of your games
Click on “3D Settings” on the top menu and uncheck “Show PhysX Visual Indicator”.
This indicator can be a handy troubleshooting tool if you want to check out your PhysX performance. If your game is running slow, then you may want to make sure that your video card’s GPU is actually doing some work. Some people even have two video cards and want one particular one to process all of the PhysX. Using this tool can help you make sure that the proper card is assigned to what you want it to do. Most users don’t want this visual indicator, and it can be maddening if you don’t know how to disable it.
