Engine effects and heat blur?

[squibby]

0.60 has apparently got new engine effects and heat blur, Has anybody seen these effects? what are we supposed to see, maybe it's very subtle and I'm just missing it?

Exhaust effects should be visible at engine start and heat blur should be visible when the engine is running. The latter is subtle as this isn't a jet.

yup its there, barely though. There's a little puff of smoke when you start the engine. the pipes vibrate (I honestly don't know if that's new though) but if there's heat blur I can't see it unless the engine actually needs to warm up lol

Cheers, I'll keep an eye out for it next time.

I haven't seen anything yet regarding blur effect. it must be very subtle indeed. can anyone post a picture of such blur effect? it may help us understand what to look for exactly.
@Martyn can you help us?
