Retroarch Android P-UAE core performance
My current phone is a Razer Phone 2, which has a pretty capable CPU and also supports that elusive 50hz refresh rate. However, I'm having some issues with CPU emulation set to "cycle-exact", which is certainly needed for some games (It Came From The Desert and Super Cars come to mind). In some games, the refresh rate often drops to around 46fps and the sound starts to break up. Is there anything I can do to improve emulation performance while still using the cycle-exact option? No, I don't want to try overclocking the phone...

Never mind, I seem to have fixed the slowdown by turning off freesync/G-sync mode in the menu.

Cool - how are you finding the Razer Phone 2 for playing Amiga at 50 hz - is it silky smooth? How are games like Pinball Fantasies or Jim Power?

Just great. It is indeed silky smooth. I'll have to test Jim Power again, but it ran at 50fps with Uae4arm.
edit: Both Jim Power and Pinball Fantasies AGA run at full speed in Retroarch with cycle exact cpu emulation, aga chipset, 68020 cpu at 28mhz, 8 mb fast ram. Last edited by endre1952; 13 June 2020 at 13:57. |

One thing about the Razer Phone 2. It's supposed to have an adaptive sync screen. But except for perhaps Mame4droid, it doesn't seem to work properly with emulators. However, if I set 50hz mode in game booster for an emulator, it will indeed run at 50hz, with silky smooth scrolling. I wish there was also a 70hz mode in game booster for proper emulation of PC DOS games.

I wonder if the Razer Phone 2 works with the Razer Kishi controller. I have used the Razer Kishi controller on Google Pixel 3XL and the controller is superb - it connects through USB C so no input lag and the build quality is pretty good.

It seems that you need an adapter, which has to be obtained from Razer:

Just received my Razer Kishi controller. It works fine with the Razer Phone 2, but I had to shave off a bit of the edges of the rubber grips of the Kishi to fit the phone. Alternately, you can contact Razer's customer support to have them send you custom grips made for the Razer Phone 1 and 2.

Glad you got it sorted. In my investigations, I've found that some of the newer phones that support high refresh rate with adaptive refresh rates can go below 60 Hz as well.
