More bugs to fix.
You serious?
I can pick an obvious long term issue.
Sound doesn't work (through monitor jacks) on some 144hz (non gsync) monitors (like the XL2730Z) at 2560x1440 or higher res, since September 2016. And that issue had it with both GTX1080 and GTX1080Ti.
The thread on that issue in the official forums is ongoing ever since with people raging against NV. Any driver prior to Sept 2016 and is fine.
Also another thing. Since the same September 2016 drivers the old GTX1080 overclock lost 5% perf (obvious on all benchmarks) making it 7% until the November 2016 when sold it.
If you do not believe me, pop to the TimeSpy, Firestrike benchmark threads in here. You will find my old 1080 having the highest GPU scores, however it's drivers were from summer 2016. Similarly overclocked 1080s with later drivers couldn't pull same GPU scores even with better CPUs. (had 6800K @ 4Ghz back then). Only the newer GTX1080s with the faster ram managed to beat me by couple of points, in some benches with later drivers.
Lack of features.
NV does not support FPS limiter like AMD does with their drivers (including per game setting) since the summer of 2015. Yes 3 years now for a very obvious feature.
Same applies to integrated, and very powerful, overclocking tool making the use of MSI AB (or other) obsolete. Hell it even supports Vega P states curves, chill features etc.
Yes true there are issues with AMD drivers, but they do fix them. I can name one with Stellaris and HOI IV which required to run the games only on opengl mode.
But that had to do with the game engine requiring the game developers to do their bit also before AMD.
On the other hand took Nvidia two weeks and 6 driver releases, to fix the animated gif issue which they broke making even Facebook not working properly....
But yeah, NV issues? Brushed under the carpet it seems
