Problem with draw distance

I am experiencing problems regarding extremely small draw distances, on and off for the last couple of days. I am away from home, and so i use my dead time to casually mine nodes in various areas on my half-decent notebook. However, sometimes (regardless off server pop) i am plagued by insanely small draw distances (10 yds or less) and these seem to affect the detect minerals aswell, making it almost impossible to spot nodes unless i literally stand on them. Is there a fix for this? What is causing the change in draw distance, server performance, my laptop performance or my connectivity?
