Flash games can often times run poorly or not operate at maximum efficiency. This can be a extremely difficult question to answer. However like most programming issues, this can be the result from a variety of things. It could be that the person who created the flash game was not very good and essentially left out or make a lot of programming mistakes. That would certainly be one very real possibility. Another possibility is that the flash game could be running on a bad operating system or a poor internet browser. The issue might not be with the game itself but could potentially be with the system running the game. That is certainly another real possibility.
A lot of people get confused as to why a flash games might run poorly. It is important to be more specific as to what the term “poorly” could possibly mean. The game could be running poorly because it is slow, or because it often crashes, or even because the graphics are off. The reason as to why a flash game would run poorly could be very specific to the game itself. This makes it hard to be able to quantify the mistake. You should always try to remember to figure out the specifics regarding why the flash game might be running poorly because you can come up with a reason or a solution to the problem.
Just like with many things in life, the problem needs to be specifically identify and people need to realize that each situation is unique. There is no universal reason as to why a flash game is running poorly. There are only specific reasons that are tailored to each situation and to each game. It is simply not possible to be able to address why a certain game is running poorly in the abstract.
