Is there a maximum number of cores that Accurender can utilise?

Sort of-- nXt has a hard-coded max of 32 but you get diminishing returns before than point.  If you go beyond 32 they can sometimes be used, depending on the load.  I guess I would still think of 32 as a practical limit.

ArStudio should do much better--  far more threads are created than the number of physical cores present,  the scheduler and the load balancing is much improved, and the hard-coded limit is gone.  I've only got 16 physical cores here, so it's a bit hard to test.  It's almost a moot point since I implemented noise-reduction, most renderings converge so fast now that I'm not yearning for extra cores.

Okay. Just tried to install and run ArStudio, but I get this message inside AutoCAD:

There should be an Update Manager in the Start menu.  Grab and install 0267.  If this doesn't work I'll send a link.

Does anyone know if there are any issues with updating to Windows 11 for either nXt or AR Studio on AutoCAD 2022?See More

"0295 is up, includes scale factor for preview image and stop after # passes.  Haven't gotten to New light channel option in Lights interface yet.  Check it out if you have a chance (no worries if not.)"

"Yeah-- I understand.  I just think you may find you have a similar problem in this new engine with trying to estimate how many passes will be good enough.   That can vary a lot. You're always going have some error, allocating…"

"The problem is when I'm running several renders over a weekend. How will I know how much time to allocate to each one? I wouldn't want them to run for the same amount of time, as one may over-cook to no extra benefit, while another is…"

"It's an easy feature to add, but I'm pretty sure with this new version you'll find a time constraint to be more reliable.  The rendering below is probably done already, with a noise filter, or close to it."

Peter Milner replied to Roy Hirshkowitz's discussion AccuRender Studio
"I suspect it will take a lot longer without the noise filter. These similar renders ran for 5 minutes each. nXt performed 127 passes and Studio performed 344 passes. Incidentally, is it possible to set a render running to a certain number of…"

"Pretty much the only thing sacrificed has been the sandpaper bump, and even then only in certain circumstances.  Everything else is preserved nicely including any random noise you add to color maps. Hard to say on performance without the…"
