Return of Reckoning

Hi,
Can someone identify problem with floor textures getting brighter while i`m moving? Sorry, my english cant let me name it.
Also if someone could provide solution to that.




I use MSI gtx 970 gaming graphic card 2k display and 16 gb ram.
RoR settings in Nvidia Inspector:

try changing negative LOD bias from clamp to something else and see if its getting better.

I tried Allow, 0x00000001, even tried different LOD bias values from -2 to 2, all same.
