Hello all. I recently compiled the latest mupen64plus-next (develop) on my Raspberry Pi 3 (platform=rpi3-mesa). I use 16:9 adjusted at 640x360, all other settings default except mupen64plus-BilinearMode = "3point".
The image quality is worst than the old deprecated mupen64plus (it looks like a lower resolution). It seems to be only for this resolution or not noticeable at higher resolutions. Is this expected behavior?
Some screenshots:
