It seems the load I can put on the GPU in RTPATHOCL is limited by the drawing rate I can achieve in the client program?


Yes, it is the expected, it the the result of the WaitNewFrame(). You can have bandwidth (PATHOCL) or low "latency" (RTPATHOCL), you can not have both for obvious reason ...

hey BYOB that's exactly the kind of behaviour I was talking about. Glad you had a chance to reproduce it.
And thanks guys for diving into this.
To me personally this is the only big thing that's lacking in Luxcore compared to Octane or Redshift.

Sorry, performance improvements are just inside the viewport handling. Operations like, modeling, moving etc get better by reducing the viewport size or making a region.
But unfortunately working on the shader editor or anything else it's still extremely laggy, no improvements.


This is ...

I also noticed this while playing with the new OpenCL material system in v2.4alpha.
I hope we can improve this for v2.4.


This is mostly a driver problem but it may be easy to fix: I expect the lag will be reduced if I send multiple (smaller) batches of work to the GPU instead of a sing ...

Hey,
Yeah using the same.
The problem by switching one GPU to display will be losing the computing power and slapping in an old one just to display will scale down the Vram to the latter.

Really hope this will be fixed. Kind of a game changer to have a very responsive viewport when working with ...

Hi guys,
I've recently started testing luxcore, it's an impressive engine!
Congrats for the hard work and everybody involved:)

So far everything is good and pretty straight forward, especially after the new updates in 2.3 RC1.

My only complain is how laggy the whole software becomes while using ...
