Dell XPS 17 9700 feels slow / laggy [because of bad graphics acceleration?]

Hi,

here’s the outuput:

Strangely the service is running after a restart (I didn’t install it just recently but a while back). optimus-manager --switch nvidia works also.

If I switch to nvidia everything runs almost smoothly (although I think input are a little bit delayed. e.g. typing start half a second delayed, the mouse cursors starts moving a bit delaxed, etc. ).

optimus-manager starts in hybrid mode. If I switch from nvidia back to integrated/hybrid the systems becomes as laggy as before. So, I’m guessing the main problem is the integrated intel graphic chip which doesn’t deliver its full performance(?) Is that possible?

In a best case scenario I’d like to boot to hybrid and save battery because nvidia just renders the performance heavy things. Is that achievable?

Regards
