Loops are too long

[.M.M.]

There are 40 loops per second but sometimes, 1 loop is too long. Is there something faster?

Just use SetGameSpeed() to change it, look for it in the manual, but remember more frame rates means more CPU power, so make sure the palyers of your game have fast enough computers to play your game at the desired resolution and colour depth.

It really depends on where you need it (which you could've stated, right?)
In some cases you can use a negative number: -2 = 1/2, -3 = 1/3, aso.

Thank you, I didn't find it in manual.
