It does not matter which attack-mode is used nor does it matter if its a multi-gpu system. Actually both, attack-mode and multi-gpu, influence the workload distribution. This will indirectly trigger the autotuner sooner or later. Just make sure to give it enough work.
I understand autotune is used to avoid cases where higher values of -n will in fact decrease cracking performance.
But sometimes autotune decreases performance. No?
For example:

HWMon.GPU.#4...: 0% Util, 31c Temp, 85% FanI'm using rule-based attack with gpu-loops and gpu-accel set to max (then autotune brings it down).
It's just weird that I can't seem to have all four GPUs running in a relatively high load (>60%).
