I allways had Way too low fps for my rig ( r9 390 and i5 4670 16gb ram and stuff ) (26-60fps) i put my Renegade X now on my SSD and guess what ? Fps stays now between 55- 60 fps ( vsync ) at all times. No stutter anymore
( the HDD before was defragged and stuff )
i dont know if Renegade X uses Texture streaming that much . but really i could even make 2 videos of it on my HDD and on my ssd world difference.
