Horribles lag when focus on selection with pretty good machine

Like i said in post i have horrible lags when i press F or Middle mouse button (wheel) to focus viewport on selection. Only in remastered collection ! I tried to change button but nothing change. I have the latest drivers (Radeon software 16.3.1) and a very good machine running all games smooth. AMD R9 m395x 16go of DDR4 and a skylake I7 6820hk. I also tried all drivers i can for my GPU and i have the same result. I hope somebody can help me and other guys with this problem !

Turn off Depth Of Field? It is a rather heavy effect for many GPUs…
