FIXED! (for both AC and ACC)
I came across this post on the AC forums <LINK> that describes issues with USB devices.
After disconnecting every USB thing I possibly could, including my keyboard, but leaving my Logitech wheel connected, the problem is gone. I reconnected the keyboard and the problem hasn't returned so that leaves at least one of these 2 devices as the problem: Either my Logitech Wingman joystick, or my HyperX Cloud II earphones (I have it connected by 3.5mm jack instead of USB now).
I'll try reconnecting one or the other to try and narrow down the problem but the point is that if you have this problem then have a look at your USB devices and drivers.
Whereas before the fix I couldn't run more than 12-15 AI on certain mod tracks without getting the CPU Occupancy warning, now I can run 35 and more without problem. The PHY value in Render Stats still ends up in the 80-90% range with than many cars, but it works! I figure there's still a problem with those tracks, as the default tracks and top-notch mods by lilski and JohnR never provoke that problem.
However I had this same problem last night with a massive grid on ACC for the first time (obviously all default content) so I frantically started yanking USB cables before the race start, and it fixed it. After I testing the fix in AC this morning to confirm the problem is gone there too.
