So I recently purchased GTA IV for the pc and I tried playing but it was very laggy for some reason so I adjusted the settings and it was still laggy until i had put everything on low quality. I find this very weird because I have a good pc and it can easily run other games on high settings.
If you are wondering which PC I have it is the HP PAVILION H8-1200EB.
I would appreciate any help and sorry for my bad English
