Problem "solved" the pixel amount difference between computers is because i have a fixedtimestep disabled and one of the tested computers monitor refresh rate is 75hz
If the monitor run at 75hz, in xna with isfixedtimestep=false and vsync actived the game run update 75 times per second.
When the two and more tested pcs are configured at 60hz in all of them works well and at same movement velocity.
