Gui loop time

[Fox]

What is the gui loop time, the first and the one in round brackets?


Update
Some variation, but the GUI sleep time is always 0.

ImGUI (the toolkit used by LuxCoreUI) is an OpenGL UI and the GUI loop is the time between 2 consecutive UI refresh ... apparently it is 30secs for you

Are you using something like the denoiser image pipeline plugin ? Oh, I see you are using BIDIRVMCPU and given the film resolution you may run out of memory (i.e. swapping on disk).

If the loop is too fast, the code will start to sleep between 2 refreshes in order to not eat all your CPU and GPU time.

[Fox]

No it's not swapping, i have 30GB free memory.
No denoiser or image pipeline plugin.
It's running on CPU e5 2620 v4.
The film refresh was as slow on LuxRender 1.7 if not slower, but it did not lag in there.

Here with 10 times less megapixels at 1080p res, the gui loop time is 2000 times faster and the lag is almost none.

If you want to reduce the lag, try to increase the "Screen refresh" time as much as you can.

I tested the m and n keys in luxcore ui, didn't help.

The renderer can save film, exr png with little speed hit, but the ui itself is unresponsive to open, to get in window menu to change light layer gain.
When you get some window open, it's slow to change value, but the hardest thing is to stretch window larger (then it goes smaller or closes).

The windows blue spinning wheel appears frozen, but was actually always spinning.

I have been able to open menus just by resting the mouse cursor over menu button and when it goes blue i click it, but in that short time i was not successful.

BlendLuxCore is very usable, you can see the ui is responsive at same resolution, but It's frozen when film is refreshing.

Upped the Screen refresh to 600 000 ms, but there seems to be something else hanging the ui within few second interval or so for as long as 1 film refresh takes. Maybe i need to wait longer until the 600 000 ms goes in effect.

Have you tried the image view tool? (In the menu at the top, open "Tool", then select "Image View").

[Fox]

Yes i have it on image view mode.
