What the hell happened to exhaust manifold flames?

[Slipstream2012]

I don't know whether its just me but the manifold flames for the Spitfire and Hurricane have been toned down to almost nothing. Before when you started the engine there would be a few large tongues of flame followed by continuous almost invisible stubby flames that would be there for the duration of flight. Now I can only see the large tongues of flame at startup or sometimes when the engine is fried, however the stubby flames seem to have been removed completely.
It all started when the Su-26 was introduced and somehow, probably through a copy & paste error the Hurricane seemed to acquire an invisible set of Su-26 exhaust manifolds from which you could see the flames glowing through the floor of the cockpit. Rather than repairing the problem it seems like instead they removed all but the larger flames completely, which is a real shame because I used to like to lean out of the cockpit on takeoff or approach and watch the flames flickering away which gave the sense of flying a living engine powered plane. Now its like flying a lifeless model.

Does anyone else have this?
