Me being a "Computer user" and liking high FPS (60 preferably). A few months back I was Bummed my Samsung Evo SD card didn't work... I was using a regular old Sandisk 16gb Class 10. I decided to format both cards and see if the Evo worked... And it did, beautifully! I could tell a SIGNIFICANT increase in FPS in Megaman X (know for horrible lag anyways but it was almost butter) and Contra III RIGHT AWAY! Contra III (If you have a slow card) Lags REALLY bad if using a class 10 Sandisk on the first car you blow up when the game starts. With the Evo, I seen NO lag for the first time in months... I was amazed. I suggest everyone who has a better SD card that DIDN'T work before, download the latest OS, Quick format the SD card and give it a go again. You will not be disappointed. I was amazed when it didn't lag on that first car in Contra III...lol. But now after playing for a while I get a 0x61 error when loading up another game. weird.
