Description

The game works perfectly, except an annoying issue with the mouse were the sensitivity is varying, slowing down and accelerating making it hard to aim in game. Feels a bit like having dust under your mouse sensor(this is not the case).

  • Intel Core i5-4670K
  • GeForce GTX 970, Nvidia proprietary 396.54
