Sometimes the drivers work better than before but almost as often, the drivers create problems instead of solving them. Nvidia drivers have proven themselves to be much more reliable over the years. If you have no choice but to get a computer with Intel graphics, you’ll want to ride heard on updates and back them out if they cause problems.
