The Idolmaster One For All [BLJS10260]

Hi, i got idolmaster ofa and im having graphical glitches when it comes to close up shots in MV like theres a blurred vertical line, and then a huge chunk of blur on the chest area. and my computer cant process 5 idols on screen like the framerate goes to 40 and it lags animations and audio and ive been tampering with my settings and im getting the same results.

On Idolm@ster 2, it runs and looks completely fine at high quality when theres 5 idols on screen.
