Quick slideshow in MP is too slow

[Wotan]

Hi,
I'm a 3d animator and to check my render tests (frame sequences, usually png fullhd) I used XnView classic, quick slideshow at 20ms delay. This setting guaranteed a 25fps playback (I don't know why not 50 fps if 1000ms / 20ms = 50, but ok, no matter, I could get 25fps and no need more).

Now I installed XnView MP, but the delay can't be less than 50ms. This produce a very slow playback and it is completely useless.

There is a way to get a 25fps playback in MP too?

Thankyou for any help.
Gian
