At first I thought there was hardly any change, still getting stutters and terrible fps with massive drops....well I have just had another game but this time lowered the texture pool and all 3 shadow settings and it seems to have improved quite A LOT!
Games seemed smooth and for the first time was seeing highs of over 100fps, it still drops though but over all it was MUCH MUCH smoother with all round better performance, I have most other settings on medium and my specs are
i3 6320
gtx 970
8gb ddr4
windows 10 pro
normal hdd
if you are still struggling with stutters etc then try lowering the texture pool and all 3 shadow options, seems to have worked for me (fingers crossed lol)
