S7: interpreter and JIT Recompiler giving same speed..?

[mashakos]

Have another question. I have two games loaded on my s7: wind waker and nba street vol. 2

Wind Waker runs at 5fps with heavily corrupted graphics (half the scene is missing with a black background) while nba street vol. 2 does not exhibit any graphical corruption but runs at 2fps.

Is this related to the new vulkan drivers ..? I am not sure if I have the latest samsung update as I installed a custom rom last month which I haven't updated since.
