I got a brand new GTX 1070 Strix hoping that I would be able to run difficult games like The Witcher 3 and ARK: Survival Evolved. When I installed it I realized that I can't even run games I USED to be able to run like GTA V or Overwatch. When I play Overwatch I run at a fluctuating 30-60 FPS and in The Witcher 3 I run at a solid 40. I even turn these games down to low settings and it barely makes a difference. My specs are GTX 1070 Strix (current drivers: 378.49), i7 4790k 4.00 GHz, 16 GB RAM G.SKILL Ripjaws X, 1tb Hard Drive (around 230 GB free), 700W power supply, Win 10 64-bit. I keep the TweakII settings at a regular Gaming Mode.
