LG VX-9400

I just got this phone a few days ago and I absolutely love it. BUT.... I have encountered a problem that may just make me have to return it. So far I have downloaded 2 games onto it, Derek Jeter Baseball and Super KO Boxing and they both run SUPER SLOOOOW. I had both games on my last phone (KRAZR)and both ran great. But on this 9400, the games are almost unplayable, particularly Jeter Baseball. Has anyone else had this problem??
