Hi Martin,thanks for looking into this. Over here we use playback ALL frames
(vs Realtime) and limit the max playback speed to "scene frame rate" in the
playback prefs. When switching to realtime (RT) on the playback tab, this
playback issue becomes even worse. When we don't limit the playback fps we
don't notice a slowdown and it will also play back at 200+fps. It only appears
once the the frame rate has been clamped.
We have tested the scene on several machines(with slightly different hardware
settings) and some have it more apparent than others(One of the machines
doesn't seem to have the problem, although the graphics card is still the
same). In XSI 2014 sp2 the scene plays back well on every machine.
This is a bit of a puzzler!

Hi Tim,
I don't think I can repro - could you please describe what exactly is happening
on your side?
Over here your scene plays back with either >220 fps (no vsync) or with
stable 60 fps (vsync enabled).
I left it running for a few minutes and could not find any noticeable slowdown
or increase in memory consumption...
What is happening on your machine?
Cheers, -M

Hi Sorry for the double post, I have attached a scene which demonstrates the
effect. When we loop through the animation we occasionally get a stuttering
effect and a noticeable slowdown. It doesn't seem to be memory related, at
least the process manager states the ram is constant. Changing v-Sync didn't
fix the problem either. I wonder if it's hardware related? We are using HP Z420
machines (Quadro 4000 graphics card, Xeon CPU E5-1620 @ 3.6GHz )Is anyone else
able to recreate this? it seems to only effect 2015.Regards,Tim
