I've checked both Pokemon Alpha Sapphire and Senran Kagura Burst and I am not too sure I am seeing a big improvement over NTR. Senran Kagura runs a lot smoother using NTR, but with the new ARN option, I am not seeing the same level of smoothness. I couldn't really tell much from Pokemon, but I think the ARN option made things a bit better. Maybe. I don't have the best eye with these things, unless it is some SERIOUS lag. I also tested the ARN option in Code of Princess, which is an absolute lag-fest in most sections and it seemed to smooth some stuff out, but again, NTR provided a bit smoother of an experience I think.
I almost feel like we need someone with a capture card to get some footage of a game running at the normal clockspeed, then with NTR's maxspeed and then ARN's maxspeed, but that's probably a tall order.
