When i got into the Train it went really fast after lowered my graphics is the run still going to get accepted or not?

What was your fps set to?

im not sure i have a FPS counter but i was at 5 min and i went to do the generator where im supposed to be at finley

i set all of the graphics to low

i checked i am chilling at around 100 FPS

Yeah you probably have your fps uncapped and the train moves faster at a higher fps so your run would be invalid. In the settings for your next run make sure to set your fps capped at 60

where can i set a cap?

you can set a cap in the settings
