I meant the difference between the command Stat Unit on each system.
My thinking was that the run speed you set up was frame limited, like others suggested afterwards.
The best way to fix it is to not add movement input every tick.
you need to figure a different mechanism that is not frame rate dependent.
for instance, you could use a branch, and add the input only once the measure is set.
Time = delta seconds + time
if time >= .5, then add input and reset time.
Needs to be something along those lines to offset the difference in acceleration.
