Flickering when using retimer

[Mr.Blank]

When I render out (using mental ray) default cache there's no flickering but when I retime the simulation to 0,5 and render Post cache there,s flickering on the smoke no matter how high I set the Sampling quality, the Final Gather quality and the Final Gather map interpolation.

The same setting for used on the Default cache yields no flickering.

Any hints as to how to avoid this?
Scene attached.

PS: using fumeFx 3.0.2

Hello,

Scene looks okay, but didn't get chance to sim and render it.

Have you tried the Scanline renderer ?
