Hey there,

I am noticing a strange issue with Maxwell Fire in a Windows environment. For some reason, each subsequent render takes longer and longer to preprocess... it feels like the old data is slowing down the new data. This occurs on both GPU and CPU rendering in Fire. At this point, by view #5 I can literally watch the voxelization process crawl by percentage point by percentage point.

Has anyone else noticed this?

i have noticed that the voxelization process in particular is a lot slower than 3.2.
on some scenes where there is very few geometry it takes way too much for the simplicity of the scene.
I can not say if its related to your issue but yeah it feels very sluggish.
