using jrvr, if I press pause then start again, render times consistently blow up which makes jrvr painful to use (have to stop/start every time instead). I guess this might be a windows or gpu problem but it's specific to jrvr rather than madvr or anything else.

Have not noticed this on my setups (Intel/nvidia).  Is this your AMD 3600 HTPC? and what GPU are you using?  It almost sounds like it going into low power mode when paused and not coming back out?

[mattkhan]

yes, amd 3600 with nvidia 1060

power mode is optimal (the default I think, never had cause to change it)

rebooted and can no longer reproduce (typical!)

I'm pretty sure I had this some time previously and it mysteriously disappeared then too, I'll try to remember to check power/gpu performance if/when it does recur

[jmone]

Yeah - I get weird issues like this from time to time is the nvidia Power option is not changed to "Prefer Maximum Performance" over the default, and never get issues when it is.

[Hendrik]

Pausing doesn't really do anything on our side, we just slow down rendering to avoid needless power consumption (the existing frame is refreshed at 10 fps, so the OSD gets updated, resizing gets handled etc). The driver power management seems to go into a lower state but then never comes back up when normal playback resumes, apparently.

[mattkhan]

the exe, as far as the OS is concerned, is mc31 in either (madvr or jrvr) case isn't it? if so, I suppose it means there is some difference in how the renderer handles pause?

[Hendrik]

Power management is not predictable. It may just behave differently if you pause at 10 fps or 1 fps, or just render on-demand.
