at least for Anime I read that FSRCNNX is not good for things that less than 720 (will case oil pant effect), is it possible have another options like SSSR and Ravu? as they good for those cases

Despite being based on FSRCNNX, the latest models are actually very different in some important ways, and the LineArt models have been trained with an Anime dataset, which makes a big difference. It is true however that for more than 2x there are more artifacts, but not much more can be done with only 24 filters.

Anyway, to implement RAVU it is necessary to load a 32 bit texture, which I think is not possible with AviSynth. SSSR seems definitely possible, but it would not fit in this application, and also I'm not very interested.

so that mean AviSynthShader need update to support float (32 bit)? maybe with opengl and Vulkan too

Avisynth Shader supports 16 bit half-float for internal processing, which should be enough, but it doesn't support 32 bit float input. The problem would also be to load a floating point image in AviSynth since ImageSource would not work. 16 bit integer is useless because there are negative values.

AviSynth Shader would surely also benefit from an update to DirectX 10 or higher, which would mean Shader Model 4 -> no limit on the number of constant registers per shader -> more filters per convolutional layer -> better models (and also slower ).
