High Sierra Graphics Performance Issue (Nvidia GPU)

To those who suffer from slow graphics performance since High Sierra:

After months of suffering, I found a remedy: Nvidia Web Drivers. Basically an Nvidia maintained version of video card drivers.

For some reason, video card drivers on macOS is in Apple's hand. Apple does not release stand alone video card drivers, they include this in macOS releases. However, Nvidia does have its own version of drivers, and they are called Nvidia Web Drivers. It has nothing to do with Web. It's just a differentiator from the Apple-provided driver.

Nvidia does not list these drivers on its website. But if you search for 'nvidia web driver mac' + macOS version (aka. 10.13.3) in Google, you will find a bunch of download links listed in various blogs, posts, etc, which really are links from Nvidia's website.

After installed this driver, my performance issues were completely gone. Everything runs perfectly just like it did in Yosemite era. It even resolved the freeze issue when sometimes my MacBook Pro awakes from sleep when my 4k external monitor is connected.

If you have a Nvidia GPU model this is definitely worth trying. Hope this helps. Thanks.
