Hello guys. I have a ryzen 5 2600 and a gtx 1070. Rise of the tomb raider runs pretty good all the time with dx11 except from cpu intensive areas where the fps drop in the high 50's. However, with dx12 enabled, in the same areas, I have about 10-15 fps more but sometimes the game has very small stutters. In the ingame benchmark I always have small stutters with dx12 enabled(the stutters are not very frequent). My psu is the evga supernova g2 850w 80+ gold. Cpu temp while gaming is 45 degrees and gpu temp is 75 degrees. I have 16gb of ram. What could be the problem? Thanks in advance.
