Mostly CUDA, sometimes wrong, usually measured

I tested this tonight. The issue went away once I changed one setting and restarted the stack cleanly.

I'd approach it in a boring order. On dual 3090, the easiest win is often to back off the aggressive settings and see whether the problem survives. A lot of these threads end up being one bad config plus a pile of conclusions drawn from it.
