I’m facing micro stutters (or I don’t know how to call them). it happens when plugging my device to and usb c to hdmi adapter (I tried several) and mirroring the screen to the display.
I did a video on reddit so you can see,
My phone is an exynos 990 with Mali G-77
Also I tested another standalone emulator like nes.emu, which uses fceu as well, and works perfectly. I also noticed nes.emu uses “external display” option and goes fullscreen on my display, unlike retroarch.
I want to dedicate this phone for gaming, but I can’t.( I tested another phone, an s23, retroarch works perfectly.)
