I have one of the new XPS 12 convertibles. I have to say this thing is a snail. I have set the graphics options to maximum performance and I am still having low frame rates.
I play Star Wards Old republic with friends and they're beating my frame rate with a standard Surface Pro. I have an I7 with 8 gigs of RAM and the Intel 4400 graphics. I know it will not run as fast as a dedicated GPU, but the frame rate is in the 20- to low 30 range.
It looks like Intel has released drivers, but I can't install them. When will Dell push out the new drivers? Are there any other options to check?
