I got ShadowPlay to work by reinstalling the drivers and choosing the "Express" Install setting and after the driver finished installing, ShadowPlay turned on (haven't tested yet). If choosing the "Customize" does anything to SP working, I don't know... I deleted the NvStreamSrv, LEDVisualizer, and the N3DVision folders since I had no use of it (Streaming and N3DVision), or was incompatable (LEDV) before the reinstall. My logic is that there's simply is no use wasting SSD space and having useless processes running... I did that with all the previous drivers and had no issues since Mobile GPUs were not supported for a lot of GFE's features. Now it looks like to get ShadowPlay to work (Capture Service most likely) you have to have streaming capabilities (Streamer Services)... It is disappointing that for one, Nvidia cannot add a few lines of code to delete the old driver folder(s) in the Nvidia folder in C: and the Installer2 folder in Program Files/Nvidia, and separate the different features so that we can choose what we want to install. They used to be able to do that...
