What setting did you end up using. also OP are you still using this since you upgraded to 8.1With the CPU power unlocked, the surface pro work like a desktop!!
I can draw pictures with 3000 x 3000 px or even higher with no lag!!! ( Im using artrage )
Tested gaming with Sonic Generation, very smooth!!! before its lag as hell
Tried a FPS game called Spec Ops 2, its playable with a little lag ( native resolution )
All I can say is... I LOVE YOU OP!!!
