I didn't have any issue with games using the Unreal Engine 4 when using 16.40.2902-radeonpro-winx32x64-dell-mobile software but when I installed the newest Radeon™ Pro Software Adrenalin Edition for Dell Mobile version 17.12.2 I noticed graphic issues with a certain game called Dead by Daylight. My issue can be described as the visuals are having a seizure or like playing on a integrated graphics with 1-5 fps while actually getting 30-50 fps. It goes away when I put the game in windowed mode it does if for another game called Fortnite which uses same engine but it goes away when I have v-sync on. I think have narrowed it down to the amd driver version 22.19.693.256 date 12/1/2017 as the cause which I get through a Windows Update. I don't any issues with any other games besides these two which both use Unreal Engine 4. At the moment I am using only what I got through the Windows Update and not using the amd software. Let me know if there is anything else I need to give.
Edit: I went to the device manager and did a roll back to the AMD FirePro M6100 FireGL V driver version 15.200.1045.0 date 6/22/2015 and the issue went away which confirms my theory that the amd driver version 22.19.693.256 date 12/1/2017 is the cause and need to be patched.
