I installed Batocera on a Thinkpad T61 (Core2 7100 + Intel 965 Express chispset) and anything works great except my favourite scanline filter to get CRT effect. To describe the issue, I don't see emulated scanlines on the screen but a mosaic effect. This means the filter is enabled but not working properly.
The LCD screen of this laptot is 1280x800. Perhaps the scanline filter doesn't support this resolution. So, is it possible to setup this filter ?
I also tried all CRT shaders, some of them have a very nice scanline rendering but the framerate slow down and games aren't playable. As example the Super Nintendo emulator run with the CRT Pi shader under 15 fps.
The laptop has a dual boot between Windows 10 (1803) and Ubuntu (18.04) and each one can run SNES9x with a very nice CRT effect at 60fps. Under Windows 10 the video engine use DirectX and under Linux it use OpenGL. This means hardware is competent. But I don't use .glslp files as shaders in SNES9X otherwise the framerate falls under 30 fps.
So is there any other method to filter the video into Batocera ? I'm running the 5.17 release with x64 support.
