I just did some test encodes with the recent git version. All the now default enabled features (experiments) have massively increased the VMAF score compared to a few months ago. Just judging by VMAF, as flawed as it may be, AV1 is now way above x265.
Also tried some options to speed up encodes. Seems like --cpu-used has very limited effect. Encoder always ran on just one cpu until I supplied --tile-columns=X but that is bugged, only the leftmost columns comes out correctly, the others are basically broken. And even then it doesn't saturate any cpu completely.
