Shader CRT-Royal keeps flickering #1497

Open pomka85 opened 3 months ago

pomka85 commented 3 months ago

The shader "CRT-Royal" doesn't seem to work properly. The image flickers constantly (especially on the SNES Core). I tested the whole thing with the current version (v138). Is there a way to set the parameters yourself in the shader settings (ares-v138\Shaders\crt\crt-royale.slangp)?

Thanks in advance for the help!

It's because SNES core (among others) always outputs at ~480p instead of 240p

Is there no way to reduce the video signal from 480p to 240p in the emulator settings?

The SNES hardware can change its output resolution at nearly any time. Sticking to a constant output size was a choice Near made to simplify the rest of the SNES video output code, so changing that would be a lot more involved than just adding a setting.

Thanks for the explanation! Is there at least the possibility of turning a few adjustment screws in the settings of the Royal CRT filter so that it works? Why do you offer a filter that doesn't work properly?

Going out on a limb here: it works for other systems that are as low-res as you might think. Sega Genedrive comes to mind, that only switches horizontal resolution.
