While discussion some of the slowness of the UI in Max on FB I've ran into an interesting observation:
print (renderers.current)
for i= 1 to 5 do
( renderSceneDialog.close()
t=timeStamp()
renderSceneDialog.open()
print ("dialog time to open: " + (timeStamp() - t ) as string)
)
This piece of mxs times the amount of time it takes to open the render dialog..
Time recordings below, in short it shows that scanline and V-Ray have a constant open/close time.. while Corona get slower and slower at each open/close cycle. That slowness sticks even when switching back to another renderer.
Tested on Max 2018.4, Windows 10, GTX1080.
