I'm so glad that I finally found a computer I can use AND get the G2 rooted after logs of issues with that computer. The SD800 is made for thrashing Tegra 4 games. It's a shame that developers limit the options due to pressure on Nvidia so they can market the Shield. I don't see frame rates drop at ALL and I'ge completed the main campaign and now working on global side missions. There isn't any difference in performance between the G2 and a Tegra 4 device (noticeable at least) and their auto detect should see thst and not have me change the value to "3" on my own. They're in it for money, and I don't blame them and they made one hell of a fun zombie shooter.. Though I admit I've been playing NOVA 3 recently as that's a "real" game to me. Much better gameplay and the IAPs are just those alien guns and are permanent and cheap (I don't pay for in game crap but bought those as I felt the game was worth more $$... I'd happily pay much more for more real games if they followed thst model. Sure Dead Trigger 2 is free and can bebeaten easily with out paying but for all the good weapons you will have to wait forever to research the even after finding the blueprints.. (but lol).. But that's another story.
Thanks for the tip here and the game looks so much better (it was amazing before with the particle and liquid effects but now with the addition of more and real time shadows and extra detail all around... Awesome.. Thanks!
