Why are Theia and Gaia so slow?

Nothing to do with interlacing. That would be only horizontal lines. Since there are both vertical and horizontal lines, it’s something generated by the AI. That first video comes out mostly okay when processed with Artemis HQ. Not to mention I don’t trust TVAI to know how to handle standard DVD MPEG2, so I de-DVD it before using TVAI and that always includes deinterlacing if needed.
My only use for TVAI is upscaling DVD to FHD. That report on Theia was made as a result of trying to find some use, ANY use, for the Theia model. (It took lots of back and forth and 5 updates for Topaz to fix the inputs so they would all affect the output correctly.) Nyx was not out yet. It had been well discovered that Proteus is the best when the source has been cleaned of noise. I was hoping Theia would be a good option.

Heh, the same thing happened with Nyx 2. I very thoroughly tested it to see if it would be a good denoiser option and it failed.
