No, your render queue is empty, it should be 7-8 / 8 or maybe 6-8 / 8. In a similar fashion the present queue should be at least 2-4 / 4. The rendering time looks OK and even if it was paused the render queue should be full (present queue would be 1-1 / 4).

Are you using DXVA2 native decoding in LAV filters? This is known to provide poor quality on Nvidia GPUs, use DXVA2 copy-back instead. Still you might not notice, the issue is only a slight blurring of the chroma planes.

Your source may be soft enough that there aren't any visible differences, even with SSIM compared to Bicubic. SSIM is good at preserving single pixel scale detail and fine texture but if you don't have any in the source you cannot preserve anything.

Don't use DXVA2 native! Especially on Nvidia GPUs, but you don't want to use native decoding at all. Use DXVA2 (copy-back) instead.

The OSD doesn't show a decoding speed issue, the decoder queue would be empty if that was the issue, and the (DXVA2) indicates hardware decoding is active.

When using native you cannot pick the hardware device to use (it has to be the same device the display is plugged into) and you are not playing anything right now, which is why the Active Decoder is inactive. Look at that same screen while playing something.
