Surface Pro 4: Framerate Issues

Does anyone else use a Surface Pro 4? I can't get anywhere near 30 FPS. I just don't get it.

My setup:

* Plugged in, high performance power settings
* Shadows off, weather off
* Project Mercury, disable core parking
* Fullscreen (Windower or not)
* MIP mapping, high texture compression, fonts compressed, maps compressed
* Bump mapping off
* Environmental animation: normal
* FFXI resolution 1920x1080
* Desktop resolution 1920x1080
* Directly after booting Surface (no cooling issue)
* Windows Updates caught up

I'm in town looking at two players and I'm hitting 15 FPS. Turning on weather shoots me down to around 10 FPS.

I'm going to assume that intel integrated graphics is the issue off the top of my head, FFXI really dislikes them

I've run it on a 3 without any adverse lag, I'd say try a different driver version. (Mostly default settings though).

It's a Microsoft product. You actually expected it to work?

O.o ?
