My PC is supposedly 20% faster than that, but my Fritz 7 (Jan 2002 update) takes
over 100 seconds instead of your 41 seconds to switch to f4:

21.Rhg1 Qb8 22.Qe2 e6 23.Bxc4 exd5 24.Bb3 Qc7 25.Qd3 dxe4 26.fxe4 Bc6 27.Nxc6
Rxc6
  ²  (0.44)   Depth: 8/28   00:00:00  277kN
  ²  (0.63)   Depth: 12/36   00:01:20  42340kN
21.f4 f6 22.f5 fxg5 23.hxg5 e6 24.fxe6 Bxe6 25.Nxe6 Rxe6 26.Qf7 Rxd5 27.exd5 Re7
  ²  (0.66)   Depth: 12/36   00:01:47  56684kN
  ±  (0.72)   Depth: 12/38   00:02:06  67263kN
