Works when tweaked properly: I had to keep tweaking settings for it to work well. Galaxy S7 Edge is my example. There are hella choices for rendering options and more. The trick is to configure screen resolution  frameskips  and emulated processor overclocking. Initially the default 100% psp's GHZ is choppy (audio too)  I use 200% psp's performance  achieving full intended speed on Grand Turismo. Battery drain is impressively low unless your display is bright and/or high resolution. I expect good newish phones to use this app well.
