Hi. So i saw a video where a guy tried games with their recommended system requirements like GTA4 with shadows turned on with 2gb of ram, a radeon hd3870, and a core 2 quad at 2,4ghz and at 1080p. It ran at 35fps. I have a laptop with 8gb ddr3 ram, a radeon hd8750m 2gb 128bit and an intel core i5-4200u 2,3ghz. When i run the same exact game i get 24fps on the same resolution WITH SHADOWS TURNED OFF while i have a much more powerful config. Why does this happen? Also in GTA5 at 720p minimum settings it barely hits 40fps. Does the M in the model name of my gpu make it much weaker than a hd3870? The drivers are all installed correctly, the newest of them. I'm running Windows 7 ultimate 64bit. What could be the issue here?
