Actually I am now going to share 2 fixes. 1 fix is for increasing performance and the other is for killing it:
For gaining performance don't run games as root,for further gain, you can create a .ini file as I mentioned before with ForceExternalZBuffer=0 but please don't do that with accelerometer based games, or it may stop them from working properly.Also I have found if we remove the library libSDL_mixer-1.2.so.0 and then create a symlink with the same name to /usr/lib/libSDL_mixer-1.2.so.0.2.4(In PR1.3) it will give a little performance boost(I have tested it.):

Code:

sudo gainroot
rm /opt/preenv/lib/libSDL_mixer-1.2.so.0
ln -s /usr/lib/libSDL_mixer-1.2.so.0.2.4 /opt/preenv/lib/libSDL_mixer-1.2.so.0

Sometimes, you may see that your game has too much performance and Sadly,screen tears happen, so for killing performance to eliminate the issue you just need to enter the following command(s) in the .ini file:

Code:

WindowSystem=libpvrPVR2D_FLIPWSEGL.so
ParamBufferSize=(Number of bytes you wish, you can increase it to 8,16,20 and even 40 millions but please don't increase it too much or your device will be crashed)

I have tested the method,but it still seems to be dangerous.so please try them when you are absolutely sure.
