I just want to report my finding:
With version 0.86.1 I reported a heavy increase of rendering times (no drops for me, just higher timings) in exclusive mode with FRC on and default flush settings.
Madshi recommended to increase 'present frames in advance' to 8 which did nothing.
Playing around with this setting I increased it even more and rendering times are back to normal!
Anyone able to explain this? Does the renderer need to wait for something presentation related?
