what model is it? also, there are known issues for older DLP's especially when it comes to gaming, ranging from a noticeably delay to the rainbow effect. since your's is only 2 yrs old it shouldn't fall into that category, but still possible, and you shouldn't need to replace that bulb yet, depending on how many hrs you've used the set so far. you should REALLY head over to AVSForum.com and ask, they are a wealth of info for stuff like this.
