I’ve now implemented an all-GPU-compute pipeline in a Pathfinder branch, avoiding the rasterizer entirely (CPU still used for tiling). However, so far it seems that using compute shader to create vector tiles and the standard GPU rasterizer to composite them is fastest…
No, I’m not—I have a branch of Pathfinder that does blending in compute but keeps basically everything else the same. It’s a regression…

(At least on my MacBook Pro integrated and discrete GPUs! Of course things could be different elsewhere…)

We are probably talking about different things. I assumed you were doing the piet-metal approach but you sound like you are doing regular PF3 emulating fixed function blending with compute. I would not be surprised if the latter is a regression
