So I've been searching and studying up on game loops and decided to go with deWitter's(the final version with interpolation). Yesterday I implemented the loop into a simple test game to see how it works, and it worked fine. My little circle would move across the screen very smoothly with no problems at all, so I saved everything and took a break.
Okay.. now here's the problem: I came back later to check it out again, but this time there was a slight stutter when the circle moved! I had no other winndows open, only CodeBlocks and the program, but when i first successfully tried it, I had Chrome open. so I tried it again with chrome open, and it didn't stutter! but when I try it with nothing open, there's that small stutter again. I looked at the code over and over, and it was exactly like the code from the (site), so I am positive it is not a problem with my code.
It's very confusing because it Really does work fine,the small stutter is very subtle, but it is there. I am using SFML 2, so maybe there is a problem with the clock function? What do you guys think? Is this even a programming problem or just my pc?
