Disable Frame Blending in OW?

My game always looks like it got this Frame Blend postFX (a little similar to Motion Blur). It looks like i’m watching a movie and I dont want that at all, I just want bare frame per frame.
The effect makes my game looks a tiny bit grainy and sleepy whenever i move my camera look, even though the render scale is set to Automatic 100%
Anyone got the same problem ?
Specs : i3-4xxx , GTX 1060

I have video of what it looks like, but don’t know how to post here

Your processor is the absolute minimum required to run the game, so it’s probably having trouble processing it any faster than what you’re seeing.
