nvidia is a loving company aiming to make the most powerful GPUs ever, why would they slow things down with a program
because you need a program to install graphics drivers with?
And you only need to run the program when you want to install the newest driver?
Like the putting the Game Ready Drivers behind a registration is annoying, but it's not a terrible inconvenience.
You can still download the quarterly drivers off the website, this is only for the #bleedingedge drivers.
i assume, performance-impact wise, the most it would do would be making start-up process take like
maybe 5 seconds longer at the most?
you can probably disable it from startup anyways so either way it's a non-concern
As long as you know how to disable services/startup programs, you can disable it yes.
The main Geforce Experience program doesn't even startup until you actually want to use it. The service that normally runs on startup just checks for driver updates and tells you if there is one.
TBH the only "bloatware" part of it is that the Streaming program that runs in the background, although I'd have to see if you can disable that via the startup services.
