GPU viewport performance

Is possible to do inside luxcore code 2x2 during input and navigation and switch back to 8x1 automatically right after ?

It is but it is a parameter BlendLuxCore doesn't expose (the number of samples it will take the transition from block to pixel rendering).

Just show me wich line i should change in wich file ( with the appropriate suit of string and number ).
Will just want to copy paste new test code line from you and see if it make any difference.

As DADE said here :

Wich setting control number of sample before transition ?

Code: Select all

# Render a sample every n x n pixels in the first passes.
            # For instance 4x4 then 2x2 and then always 1x1.
            definitions["rtpath.resolutionreduction.preview"] = resolutionreduction
            # Each preview step is rendered for n frames.
            definitions["rtpath.resolutionreduction.step"] = 1
            # Render a sample every n x n pixels, outside the preview phase,
            # in order to reduce the per frame rendering time.
            definitions["rtpath.resolutionreduction"] = 1
            """

            # TODO figure out good settings
            # 4, 2, 2 seems to be quite ok for now. Maybe make resolutionreduction dependent on film size later.
            definitions["rtpath.resolutionreduction.preview"] = resolutionreduction
            definitions["rtpath.resolutionreduction.preview.step"] = 2
            definitions["rtpath.resolutionreduction"] = 2

It should be this one.

This part is commented so i copy past it outside of the string then play with the number but it doesn't affect anything . so not sure about it.

            # 4, 2, 2 seems to be quite ok for now. Maybe make resolutionreduction dependent on film size later.
            definitions["rtpath.resolutionreduction.preview"] = resolutionreduction
            definitions["rtpath.resolutionreduction.preview.step"] = 2
            definitions["rtpath.resolutionreduction"] = 2
            definitions["rtpath.resolutionreduction.step"] = 1000

What i've done (the last line).
