Making sure all you device drivers, browser, flash player, and Java are up to date and cleared of trash (temp and un-needed) files is just part of routine personal computer maintenance.
Don't forget to keep the computer's heat sinks (CPU, power supply, graphics card) and cooling fans physically clean too.
A lot of players have meter stutter, and other game play issues in part because they don't do the required personal computer maintenance for 2 main reasons:
1. They don't know how or what needs to be done.
2. They can't be bothered.
