Need help with Dante's Inferno

[appollo14744]

I have seen a lot of youtube videos of people playing Dante's Inferno on PPSSPP with pretty much flawlwss graphics. But I have always had the game to flicker so bad even when using the same settings the people who made the video used that it makes the game unplayable. Is their a way to get the game to play without all the flickering, and if so could someone please give me the settings to make it run properly? Any help with this would be greatly appreciated.
