oh oh oh wait, yeah its probably cache or something problem. I continuing playing Far Cry 3, played 2 minutes i minimized game window (paused). and after some minutes i continued playing again, and you know what? the problem is not beginned immediately, its started after 30 seconds of play. I think its saving something shader cache while playing, and its seems filling and deleting cache, and there is problem on deleting process (each 3 seconds, synchronized lagging). I think this is it. I still dont know anyway. but this is strange absolutely.
or this is a CPU problem, not a graphics... repeat: i reinstalled with format windows 8.1

ZoDX32: Thank you very much for joining the Intel® Graphics communities.
In order to try to fix this problem we can try a BIOS update to the latest version, 1.03. Please get in contact with Acer to gather the instructions of how to do it, on the link below you will see the file needed. Also, to install the latest graphics drivers provided by them will be a good option to do, please look for VGA driver from Nvidia and Intel:
Since the processor works with Intel® HD 4600 graphics controller, if the problem persists after trying the steps above, another thing to do will be to install driver version 4624:
Any further questions, please let me know.

And now... the problem has rised again... ahh... what is this ****
its definitely something growing like a cache or cookie, and if it becomes too much the lag begins... i dont know what exactly is growing...
Thanks for help. I solved this problem by changing CPU's termopaste. Current was very dry and crack. Im so glad now, i've not changed about 2-3 years.
