lightmix doesn't refresh instantly

When rendering, Lightmix in the VFB doesn't refresh instantly (like in previous versions happened). For example, if i switch off a light source, i have to wait a bit of time to see effects on the image. Do you know why?

Works fine on my end on a simple scene. Mind if you record a video illustrating the issue?

Thanks for your patience, i was on a deadline.
Here's a video with a fresh finshed render.

As you can see, in this case changing lightmix settings don't affect the final output at all.
This happen in a similar way when rendering, where lightmix tuning is visible on output only with a certain delay (30/40 seconds on my machine).

Interesting, can you save this render to a vrimg and send it to us ?

[yavor.rubenov]

Thanks for the vrimg file. Here it seems to behave as expected and turning lights on/off is immediately visible. Is the problem reproducing for you if you restart Max and just load the vrimg file into the frame buffer without any rendering ?

[salvatore_monteduro]

Yeah, if I do that works fine for me too and it update any mod in real time.
