Install Xanmod Kernel. I love it to pieces, and works great. Very reliable, and stable. It is a kernel designed for gaming, and makes some performance improvements to the system as well. I believe your having issues because Pop!_OS comes with an outdated kernel. Thus installing an up-to-date kernel will give you the drivers that are necessary for your computer.
Install:
echo 'deb http://deb.xanmod.org releases main' | sudo tee /etc/apt/sources.list.d/xanmod-kernel.list && wget -qO - https://dl.xanmod.org/gpg.key | sudo apt-key add -
sudo apt update && sudo apt install linux-xanmod-edge
Reboot, and your done! :D
