Keis Retro Gaming | PPSSPP Vulkan vs OpenGL - Android @KeiRetroGaming | Uploaded November 2021 | Updated October 2024, 1 hour ago.
Testing performance for PPSSPP emulation across Vulkan, Open GL. Both chips were turned to the highest scaling possible to where the FPS would dip. 4X Scaling (Captured on a MI 9T with a Snapdragon 730) and 10X Scaling (Captured on a Poco F3 with a Snapdragon 870).

Timestamps:
0:00 - Snapdragon 730 Vulkan VS OpenGL
4:40 - Snapdragon 870 Vulkan VS OpenGL

Make sure to adjust your "Internal Resolution" accordingly to your chip. OpenGL seems smoother compared to Vulkan here so personally would recommend using that and the following settings below:

Render duplicate frames to 60hz - ON
Display Resolution - Auto (same as rendering resolution)
