Im using a graphics device from Nvidia series 8xxx, 9xxx, 2xx. Why is the performance all the same so low?
Recently, Nvidia built a PhysX Support into their graphics device drivers. It seems that the PhysX acceleration is set to “enabled” by default. If you deactivate it, you can, depending on the device, improve your performance from 5 up to 20 FPS. In order to deactivate it, open the Nvidia PhysX menu in the system control center of Windows, click on Settings and on “No acceleration”.
