I'm looking into RetroArch because I'm not happy with the rendering under openMSX. Concretely, I'm not happy about:
This is what I mean about the rendering: the left half of the image is a screenshot from openMSX with rendered scanlines. The right side is RetroArch with the Lottes shader. Note that it accurately emulates the RGB triplets on a CRT display:
This is a problem because I use openMSX to take screenshots and videos for the reviews here. The biggest annoyance is recording video: I have to use QuickTime Player to do a screen recording of the window running the emulator, and I need to use Loopback to be able to even record the audio.
Needless to say, this is not a good solution.
I've installed RetroArch to address this. The configuration is a pain in the ass, but I managed to get it running. It runs fine without any display filters (though the pixels look like bricks). However, if I enable any shader the framerate drops and it becomes unusable.
Do I need a more powerful machine (or GPU) for this, or is there something wrong with my settings?
This is the machine I'm currently using:
