For Android, Non-buffered mode gives major speed boost in most games as reported by many users around the forum. Since GPU is mostly the bottleneck for Android, many FBO effects such as Motion Blur, Bloom etc can't be faked in a sensible way in Non-Buffered mode thus giving major speed boost. Some Android devices doesn't run with Buffered Rendering at all such as ARMv6 that's why Henrik made non-buffered Rendering default for ARMv6 https://github.com/hrydgard/ppsspp/commi...911bd55f63
So, Android users should be advised to run in non-buffered mode unless something doesn't work correctly. However, For Windows, it gives Minor speed boost (even in low-end GPUs) as you have mentioned.

Correction:- If you look at the code:

Code:

if (gl_extensions.EXT_swap_control_tear) {
        // See http://developer.download.nvidia.com/opengl/specs/WGL_EXT_swap_control_tear.txt
        glstate.SetVSyncInterval(g_Config.bVSync ? -1 :0);
    } else {
        glstate.SetVSyncInterval(g_Config.bVSync ? 1 : 0);
    }

and

Code:

if (gl_extensions.EXT_swap_control_tear) {
      // See http://developer.download.nvidia.com/opengl/specs/WGL_EXT_swap_control_tear.txt
      glstate.SetVSyncInterval(-desiredVSyncInterval);
    } else {
      glstate.SetVSyncInterval(desiredVSyncInterval);
    }

It implies that VSync automatically disables if it can't keep up with 100% Speed. So, it's safe to say that Windows users should left VSync enabled since disabling it won't give speed boost, unless they experience some problem.
