Re: [177.70] IPP2 falling back to IPP1
Config settings changing by themselves could actually explain a lot of weird things we've seen here with performance and stability.
I see something similar. When starting nvidia-settings, especially after a few days of uptime, the screen goes black for a few seconds. If I start it again a few minutes later, this does not happen. In the first case it seems to (re-)apply settings that the hardware forgot about.
