Hello Leif, I use VESA 1280x1024 @ 60Hz / 24bit with X11.
The values I sent before are with a signal selected. Percentages change a little with the selected filter bandwidths (+-3%). Without selecting a signal the figures are: 02.27: no FFT2: 12% with FFT2: 28% 02.19: no FFT2: 9% with FFT2: 26% Hope it helps.
