The CPU figures in Settings → Calls were guesses with no unit, so they read like Task Manager's whole-CPU number and looked wildly off. I measured each model running exactly as Lotus Call runs it: real-time speech, browser-process CPU time from /proc minus a no-model baseline, on a Ryzen 7 PRO 4750GE, repeated twice.

Model	Was	Measured (one core)	Download (fetched)
DeepFilterNet 3	25–50%	~30%	17.6 MB (label ~18 MB ✓)
DTLN	10–20%	~9%	~20 MB (was "~4 MB")
RNNoise	< 5%	~3%	0.2 MB
Speex	< 2%	~2%	0.1 MB

The CPU stat is now labelled "one core".
The model description explains that Task Manager shows this figure divided by your core count, and that slower computers use more.
lotusDenoiseUtils.ts records how the numbers were measured.

The CPU column was guessed (DeepFilterNet "25-50%", DTLN "10-20%") with no
unit, so it read like Task Manager's whole-CPU figure and looked wildly off.
Measured with each model running exactly as Lotus Call runs it (real-time
speech, browser process CPU time from /proc minus a no-model baseline,
Ryzen 7 PRO 4750GE): DeepFilterNet ~30%, DTLN ~9%, RNNoise ~3%, Speex ~2%
of one core. Label it "one core" and explain the Task Manager relation.
DTLN's download was listed as ~4 MB but fetches ~20 MB (17 MB worklet with
the runtime inlined, plus 4 MB of models); DFN's ~18 MB is right (17.6 MB).
