sgs3 problem can anyone fix?

[b11aze]

Hello everyone. I have a samsung galaxy s3 from sprint model sph-l710. I have noticed that many games are incompatible or are not working. For example, i purchased nova3 for the holiday sale. But the lag on campaign mode is so bad that it is unplayable. Does anyone know of a fix for this? Is it the phone? I am willing to try anything. Thanks
