[Q] Bad gaming performance topic

Hi, i am new owner of Nexus 4 and there is one thing which is bothering me. Games are really running not as smooth as i expected from this hardware. I preformed clean install of a lot ROMs (Stock,PA,Rastapop,slimLP) and kernels (unleashed,franco,AK), i have tried overclocking CPU and GPU, changing governors to performance, flashing Adreno drivers from http://bit.ly/makostuff. Now i am running SimpleAOSP + AK Kernel .600 and what i found out is, that the gaming performance has not barely changed from stock, even if i overclocked to 1.9 GHz CPU and 487 GPU. Asphalt 8, Real Racing 3 and mainly GTA San Andreas are pretty laggy. GTA San Andreas is running better on friends old Galaxy S2 and LG L9 II.

Does anyone have any tips for gaming performance, some special rom-kernel combo, or some tweaks ? Or is this hardware really not that good for gaming ? Thanks for tips guys.
