Framerate has decrease on galaxy s3

[j_kazmi]

Can somebody help me im new and i downloaded one of the new updates and the update did help the framerate for my games increase up to around about 50-60fps but after a while they decreased down to the way it was before the update which around about 40fps.

And by the way the games i have are kingdom hearts dragonball z shin budokai and shin budokai 2. Thanks
