DCS 256OB PerfDiag: F18C F2View Engine Exhaust Black Smoke Very Costly When Camera Inside 1

Black Engine Exhaust Smoke costs a lot of FPS, compared to a different style smoke (older) used for contrails at high altitude. Perhaps some kind of clipping function isn't working and it allows the smoke to reach high density proportions that bog down the GPU, the highest FPS drop happens when the camera is practically inside the smoke, but watching that same or even more smoke from further away much better.

A chunk of the CPU usage there is used by OBS Recorder.
Tested that same FPS behavior happens without recording.
