@admiralakbar If it's an issue with the Sorian adaptive AI performance more generally (rather than that the non-cheating AI performs far better than the AiX version) then I expect it's just due to flaws with the Sorian AI - try the Adaptive AI which should be a bit better, or one of the custom AI (which are significantly better):

I wouldn't have expected LOUD to impact on Sorian's performance in FAF.
If there are maps where the AI just flat out doesnt build anything (i.e. early game), then you could post the replay as there's a chance it is something easily fixed, but Sorian AI doesnt have an active developer so there's no guarantee.
Another thing to bear in mind if this is mid-late game is that unit caps can mess with the AI, but I'm assuming it's still well below the unit cap.
