Your Dell computer works with Hybrid graphics, it means Nvidia graphics works together with Intel graphics; this configuration requires custom settings by the PC manufacturer. Intel generic drivers available at downloadcenter are intended for PCs working with just Intel graphics.
Dell drivers provide with the best graphics experience.
I noted at Dell website a new Intel custom graphics version 4483, released on 09/06/16. Also, there is a warning suggesting to update the BIOS and docking station’s drivers.
New BIOS and drivers are available on the link below: (Dell XPS 15 (9550)
I still believe the problem is with new drivers no matter you use them on hybrid graphics configuration or machine has only intel graphics, if his mashines works fine with older intel generic drivers or older manufacturer modified drivers the new ones should work too. But they dont. And everyone has identical problems. The problem with manufacturer drivers is what they are almost around 1 year old and they are not updating or they release new driver package using again old year old intel diver version . It is said by intel its better to use manufacturer modified optimized driver, but from my own experience machine with updated generic intel drivers always works better, always.
