Texture Flicker - Noise - Grainy problem

Here again, the solution before fixed something, but not all.

I think there is some bug in ue 4.10, or some issue with my hardware.
Another thing i did in consolevariables.ini:
r.PostProcessAAQuality=6

Thats for better AA, but the problem remains.

I discovered that only happens when using the 3D visor without “Realtime”(ctrl+R).
If I check ON for “realtime” view all is right.
¿?
Thas the problem.

In my Nvidia control panel:
FXAA:off
Antialiasing mode: aplication controled
anisotropic:16x
prerendered f: 1
v-sync:on
