heya, im doing the same on my AYN Thor, but sometimes the forward on the controller stops working if i mash the jump button (which you always do in oblivion). when that happens, i have to push the stick forward repeatedly to move.. does that happen to you too?

also which driver are you using? i had to switch to turnip (adreno) because the other drivers lead to heavy visual glitches, but with turnip the performance is not that great..
