Issue: EEVEE unexpected long initialization time while rendering I am rendering a scene that I have been working on for days. It has not a lot of detail, just a few not complex materials. It rendered in EEVEE fine with 1.1s per frame. I just changed some animations and scaled some objects but did not edit rendering settings.
Suddenly EEVEE is taking forever to initialize the render as well as to close it and open the next frame. When it actually renders, it takes only a second to render.
Is there any way to profile the rendering process?
I would like to try to find out:
What data containers where loaded, 
how long did what process take
Where there any internal errors that are not shown in console
Are there maybe sudden driver issues
I have had this problem three times now on different scenes. It happens randomly but sticks with the file no matter what I do.
My System info:
64GB Ram
2x Nvidia RTX 2070 blower edition
AMD Ryzen CPU
I had the same issue yesterday, when trying to render scene from animation in EEVE. It took about 25 second for it to start. It was the same with Cycles and Workbench render. There's no automatic update on blender so in my case it could be Windows or GPU driver issue. Tried previous blender release, same thing happended
