I bought my g73 about 2 months ago and it came with a modified windows. after a time (when i started playing games), i realized i was getting low performance on my laptop. then, i did a fresh format with my own windows and installed the drivers in ROG forums. there was a little ascendance on performance but not normal. I'm saying not normal because, my friend has an ASUS k53s with nvidia 540m and he's getting 40-50 fps and I'm getting 15-20 fps at skyrim. By the way, the laptop has been freezing at random times since i bought it and two weeks ago i took the laptop to the service because of this freezing problem. today i got it and tried playing skyrim and fps was still the same. (btw, after the format i did nearly all the things which has been said on the forums about gsod, vbios, stuttering and etc.) and i don't think this is the normal performance of this laptop or this graphic card.
what is the problem? or what should i do?
