PRC-X Advanced - awful interior shadows plus stippling

[Bluegunk]

I got PRC-X nicely set up for the exterior world, but some light sources on the interior are causing really bad stippling and ghastly shadows.

I've tried a couple of tricks, like switching off (or on) Self-Intersecting and bblurenable.

I'd really appreciate any other tips from the experts out there! Thanks!  

PS I do run Ultra Interior Lighting and Enhanced Lights and Effects, so I probably shot myself in the foot.

 

Here's a sample (it's worse in the game!):

OK, I improved this.  I switched off +HBAO in BethINI, Nvidia Control Panel switched off SAO, then fiddled about with ENB's shadows.

It's not gone away but is much improved.

 

No need to answer now. Thanks!
