Intel has displayed new things for DX11.1 to improve tire-smoke and tree rendering.
No more smoke clipping cars and ground during donuts, and no more leaf/smoke popping. :thumbsup:
As a bonus they say it's only a 5-10% performance loss instead of the usual around 80% ..win win. :)
But for now hardware support is by new Intel GPU, no AMD or NVIDIA (yet?).

"Existing solutions for real-time volumetric shadowing exhibit slicing artifacts due to non-adaptive sampling, cover only a limited depth range, or are limited to one type of media (e.g., only hair, only smoke, etc)"
(AVSM) adaptive Volumetric Shadow Maps and__ (AOIT) Adaptive Order Independent Transparency.
