Why doesn't heat blur work for me?

[Vampyr]

Is it weird that I don't see heat blur even when my engines are running max thrust? I'm on a GTX 1070 right now, but I remember seeing the same thing on the Radeon 6750 and GTX 1050 I used to have before this. I thought that in 2.5 the heat blur might be more visible, but I still don't see anything. So far I've only tried heat blur with the A-10C.

 

Attached are two in game screenshots plus a screenshot of my current graphical settings.

I think there's no heatblur effect in the A-10C.

The effect was there when I last played on the A-10C

Can you show me a screenshot of heat blur on your A-10C?

Heat blur is only visible at slow speeds. Try it on the ramp.

Works for me. Like sobek said, low speeds and don't put your throttle to idle.

I just tested it on the ramp and the heat blur was quite visible. Thanks for clearing that up guys.
