Question

Blur Effects Pathetically Slow

This is not a problem as such, just an observation. I just built a new i9 based Windows box with 128GB of RAM, an nVidia RTX3080, etc. It is super fast for just  about everything, but Blur is still really really slow. Granted I'm working on a very large image, but I don't see why Path Blur should take over an hour. Is blur just an inherently intense thing to do? Are Adobe's algorythms inefficient? What gives? Yes I have the cache levels set for very large images, have generous virtual memory, etc.

What size image and what settings in path blur?

I just tried it on a photograph 6720 x 4480 pixels and 16 bits/channel. It took just a couple of seconds. Tried again on another 8380 x 2377 16 bit - again a couple of seconds

Finally, I tried it on a larger image 28346 x 8040 pixels again at 16 bits/channel. That took a bit longer, 67 seconds

 

System : i9-10920x, RTX2080ti, 128GB RAM and an M2 NVMe drive with 1TB free for scratch disk

    I guess one could get really »fancy« with Path Blur, use large numbers of Paths etc., and that might have an influence on the performance, so the OP may have to provide more meaningful information.

    The image is about 15000 x 18000 and I used several pathways. Like I said I know it's big but still I wondered why it took so long. I guess I  can try looking at  my settings again.

    System:

    i9-10900KF 
    128 GB RAM

    RTX 3080 with 10 GB
    Samsung 980 Pro 1TB

    This is a user Forum, so you are not really addressing Adobe here, even though some Adobe employees thankfully have been dropping by.
