In 5.26 the internal resolution of dolphin (in the graphics settings in dolphin-emu-config) is set to “Auto (Multiple of 640×528)” at default and in ppspp the internal resolution (Rendering resolution in the ppsspp emulator config) is set to “4x PSP” at default, which causes that almost every game is running bad (with a lot of stuttering) especially on older hardware.
I know you can set “Video Mode” under “Game Settings”, “Per System Advanced Configuration” to a lower resolution, but this will also change the TV/Monitor resolution and some TVs/Monitors behave strange with certain lower resolutions.
It would be way better to set the default value for the internal resolution of dolphin to “Native (640×528)” and the internal resolution of ppsspp to “1x PSP” instead.
And then maybe have an extra option under “Per System Advanced Configuration” for the internal emulator resolution (this setting option could also even replace the “Video Mode” completely, i guess).
@nadenislamarre what do you think?
