Video driver has crashed

UT2015 crashes after some time playing (either online or offline) I’m using amd video driver 15.20.1062.1004-150803a-184226E
Here I post the dxdiag file & the log file
Hope It helps

Hi zonck,

This is a known issue with AMD 380 and 390 cards. We have checked and it seems that this error is not something we can address as it is an error with their drivers. I would highly recommend posting on the AMD website here: http://www.amd.com/en-us to let them know you are experiencing difficulties with their most recent drivers.
