*Viewport Render Toggle Switch:*
After trying some tests with a very dense particle system, I would like
to ask your thoughts about a toggle switch for Cycles Viewport
rendering, letting a user choose if Viewport rendering displays 'View'
settings /(as it does presently)/ or 'Render' settings /(like the final
Currently it seems the only way to preview /(render)/ my dense particle
system with many child particles /(//heavily reduced 'View' settings for
faster Viewport navigation)/ is by doing a full F12 render.
Would a Viewport render 'View' / 'Render' toggle also be helpful for
Cycles strand rendering Patch tests?
*Viewport Half Resolution Cycles Render:*
One Idea I had while Cycles was in very early development, having a
Viewport Shading 'Fast Rendered' option, below the 'Rendered' option.
The 'Fast Rendered' option displaying a half resolution view /(with
possibly reduced light sample bounces////for extra speed?)/, this would
be helpful for those using laptops without access to GPGPU, also while
using very high resolution displays, there would be no need to make a
very small Viewport preview 'render' window to position lights in real time.
Have tried some Viewport render tests, halving the resolution is about
twice the performance /(which I guess is logical)/.
*Couple of Questions to Finish**:*
When Motion Blur is not enabled, why does the code still affect render
speeds? Render speeds have slowed a little, even while using optimal
tile sizes, compared to before when the code was present but commented
out. Please understand this is not a complaint, really pleased MB is
there, just very interested to learn.
And finally... Does the Viewport render now display using progressive
refine, instead of the old progressive method? I notice Tile size also
greatly influences Viewport render speed even though tiles are not
visible during rendering.
Thank you greatly for your time and phenomenal programming skills!
