High Sierra with graphical glitches even with Nvidia Web Drivers

I have installed High Sierra and its working fine, except graphic glitches occur.

Hardware:
CPU: R5 2600 GPU: MSI GTX1070 ARMOR OC RAM: Corsair Vengeance RGB 16GB 3200Mhz Motherboard model: AsRock B450 Pro4

This is how my GPU shows up on About Your Mac:
