hey, can you specify your system specs please, I want to clear something out for my brother, he believes that it is due to his budget gaming build and he needs a higher gaming rig to build for this? thank you 

You've got the Motion Tile effect applied somewhere, and you've possibly got it cranked up much higher than you probably need it to be. 

Locate the instance(s) of Motion Tile in your project, and see if you can decrease the height/width settings in the effect without affecting the way it looks.
