Ubuntu 18.04 still uses llvmpipe driver#3

I have installed Ubuntu 18.04 but the display is annoying, i don’t have hybrid graphics and also i have installed the driver from software and updates.
Now coming to the specs, I’m using Ubuntu 18.04 dual booted with windows 10. I have GTX 1650TI graphics card. I’ve installed nvidia-450(recommended) driver.
