Guide:- Maximizing the performance of PPSSPP on your Android/Windows device.

I was always wondering about that but does the "Render Resolution" matters.
What I find strange here is that(buffered rendering is enabled)I don't get any speed loss between.
Render Resolution - x1
Texture Scaling - off and xBRZ
and
Render Resolution 4x
Texture Scaling - 5x and Hybrid Bicubic
The only different thing is that the graphics quality is tinny bit better and the ram usage is more(totally not wort the extra ram usage for such small change on the graphics)

I only get less speed if AA is enabled but between AA and
Render Resolution - x1
Texture Scaling - off and xBRZ
or
Render Resolution 4x
Texture Scaling - 5x and Hybrid Bicubic
there is no difference in the speed and the quality when AA is enable is as if you are using some texture filter(2xSaI for example).
You lose a lot of speed for such small difference...Linear Filtering is doing good enough job.
