[Arjun99]

Hello,
I'm a ppsspp user and my device is the lenovo k3 note(k50a40).Running on lollipop 5.0.It runs on mediatek processor -MT6752 and gpu-Arm mali-T760 mp2

Now my main problem is my games are blurry on buffered rendering and the screen is black on non-buffered.
The games which are working are :-
FIFA STREET 2
PRINCE OF PERISA (BOTH OF THEM)
DRAGON BALL Z TENKAICHI TAG TEAM

The below games are blurry:-
METAL GEAR SOLID PEACE WALKER(FROM START)
SPIDERMAN WEB OF SHADOWS(AFYER FIRST LEVEL)

Now can you please tell me what the problem is and can I fix or not.The roms aren't faulty I have checked it on other platforms.Please help me.
Thanks in advance.

I am also having the blur problem in Peace Walker. I am on the Samsung Galaxy S6 Edge+ running Lollipop 5.1.1 and settings are default minus the default virtual gamepad settings and I was sure to change to 2x psp.
