Thought this was interesting.
Was doing the Steps of Faith trial in my roulette and was doing some tests.

My CPU is a AMD FX 8320
With no spatial pack on, total computer CPU usage was at 58% and there was non-stop audio choppyness
With the trial spatial pack on, CPU usage was at 50% and there was no choppyness
I know a lot of folks have less choppyness with the spatial pack, so I'm not going "Oh wow guys the audio pack fixes it!" cause it doesn't and audio sounds like underwater garbage...
But it was curious to see the game taking that much more CPU when there was no audio pack added.

Which is weird because, in Shadowbringers I know CPU usage is still the same when I monitored it during hunt trains back when i thought my CPU was dying, but discovered the game Foxhole that I play is so poorly optimized it turns any PC into an oven, and it was triggering my CPU's emergency shut-off due to overheating but only during the massive battles that create haze of war. Only game that runs that hot. Nothing else
