Hi guys,
I've installed the latest daily, (1st of december) and :
1. VFB seems less responsive, even in my epic test scene (teapot, plane, corona sun) panning has some sort of freezes.
2. Holding on the EV slider little arrows, and dragging is lagging (has freezes) as well. Even typing different values takes longer to calculate.
I haven't investigated more because I have a project running and I've quickly reverted back to 1.5 hotfix and I can confirm no lagging and no freezes.
