An example is any of the DCS sims they all have heat blur.Uploaded with ImageShack.us

This isn't FSX, and FSX does not support light refraction or blurring of any kind.

Third pic down. Adds a huge amount of realism in my opinion. http://forum.avsim.n...04#entry1951404

Pretty much positive that's post-editing in Photoshop. Look at the 1st shot - there's a bokeh/depth of field effect to the image - that's 100% impossible in FSX. Only the most advanced game engines right now do real time DoF like Crysis 2, Metro 2033, etc.I've found no evidence anything actually does this realistically in FSX. What I've seen before are unrealistic looking hacks of the contrail or smoke system that use transparent fx files - I think it looks pretty fake though.

It's really awesome and realistic. :(

Does it flicker and morph as the real one? If this is something that is just a static picture I would hardly call it realistic.
