second, playing on intel i-gpu while owing a nvidia ? why ?

… I’m pretty sure I use the Nvidia chip for playing. I went through the advice from this thread, and I can confirm that the Nvidia GPU is very much active while I’m playing.

@Olli

and what about this raid-controller ? do you use it ?

I don’t really know what a raid controller is, would you mind explaining what you expect me to do to investiguate this?

Thanks.
