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?
