This looks really well.
Is there any version of this shader to be used with OBS? So it's not only limited to DosBox? :)
i.e. with obs-shaderfilter
Thanks, I’m glad you like it!
I am not familiar with OBS shaders, but it might well be possible to integrate my shaders with that. It is not something I would do though, but the code is open source so maybe someone else will.
I do have a standalone image viewer using the shader, and the code to that can be found here https://github.com/mattiasgustavsson/crtview
It might be a useful reference for anyone trying to use it for something else
yeah, it’s not so straightforward to find them - it’s implemented as a single-file library, so the shader code is embedded in the C code - you can find it here https://github.com/mattiasgustavsson/crtview/blob/de7897958ac1f346ca7fa3dbf5a57dab5fcc5bb3/source/crtemu_pc.h#L57
It’s a little more complicated than just a shader though - I use a couple of extra passes and buffers, to do a good gaussian blur with decent performance, and to accumulate pixel values over time, so there can be a visible blur trail when objects move. I don’t know how tricky it would be to recreate that for OBS...
I do have an earlier version of the shader here:

It doesn’t use the extra buffers, it is just a plain pixel shader. So it does not have the blur trail, and it is also very GPU intensive due to the gaussian blur being done on the full resolution rather than on a smaller buffer.
