On the solution of the PhysX physics acceleration drive of associative Y470

I don't know if anyone in the forum is using Y470.

People who use Y470 may have encountered the problem of PhysX physics-driven problems (Lenovo engineers actually say that my system is problematic.) I think it's impossible. )

Let's take a look at Y470 's graphics configuration.

Graphics card intel® HD Graphics Family

Memory 1795 MB

Manufacturer Association

Main graphics Nvidia GeForce GT 550M

Memory 2 GB

Manufacturer Association

You see, it's dual graphics.

Nvidia GeForce GT 550M is supported for PhysX physical acceleration

But Lenovo's official supply of the driver package is physx physical acceleration.

And the NVIDIA official offers the drive is with PhysX physical acceleration

Some people will say that want to use PhysX as long as to Nvidia official updated the driver can not it?

I've tried this method.

If the video driver is updated directly, it will create an icon

Abnormal (perhaps not normal or maybe Nvidia was changed later?)

That icon is Nvidia Optimus Technology normal words should be color Direct update Nvidia provides the graphics driver after that icon will be black and white for a while color

and black and white time is more. (But this time the dual graphics card switching seems normal for the perfect point can continue to look down)

Some people would say that there is another way to download a PhysX driver or not?

I went to the NVIDIA website to find a lap did not find this driver is found in Baidu a lot. The official did not provide Baidu to provide the do not know and incompatible will have other problems, so let's do it yourself.

The easiest thing to do is to download Nvidia's latest graphics driver package

After decompression, there is a PhysX folder with an MSI file to install directly

If it doesn't work, keep looking down.

There is another way is to download from Lenovo's official website n card driver and download from the NVIDIA website N card driver respectively decompression and then the NVIDIA official website under the driver package PhysX This folder copied to Lenovo's official website of the driver package under the directory

Then run the Setup Setup driver

This is the PhysX of the driver package that Lenovo provided.

The rest can also be reinstalled according to the method provided by the Lenovo engineer:

When reinstalling, two graphics drivers are required to uninstall. First go to the Control Panel-Program and function (program-uninstall program), find all the programs at the beginning of Nvidia, uninstall it. After uninstalling, locate the Intel HD graphic integrated video driver and uninstall it. If not, right-click the computer---management---Device Manager-display adapter, and locate the integrated video card to uninstall it. You will need to check if the "Remove driver" prompt appears when uninstalling. Then uninstall.

After the uninstall is required to restart the computer, and then install the integrated graphics driver, restart the computer again, and then install a stand-alone video card.

Enable dual video card functionality again

The icon is always colored and the test can use the PhysX physical acceleration (I can play the need for Speed 13 and 15)

Okay, that's it.
