There’s also RenderMan XPU - but its so brittle, if you blink to hard it will crash to desktop - but that Denoiser - there’s nothing close to it and its temporal too.

I think once Karma XPU gets adaptive sampling and per-object sampling overrides - it will really be a great contender in the market.

Redshift and Cycles compiles all on 1st render. Vray has a button to compile all (at least it used too, before it was multithreaded). Karma compiles per-feature on-demand.

Kernels have to be recompiled with each new GPU driver install or new GPU engine install.

when I add a new node into the shader it takes quite a while before the render updates

This is the compiling of new shaders.
we've improved this a lot for H20

Any chance we can get a 'compile all' option like other GPU Engines have?

I'd rather pay that cost during Houdini install or Startup or maybe even a command line tool, for example - just some way to pay that cost one time - all at the same time.
