what exactly did you expected from a AMD 4400+ & GeForce 210
Just to point out that your pc have about the same power with a gaming pc from 2004, so yeah you are 8 years behind, that means no current generation games for you.
No matter how much you upgrade your computer...Grand Theft Auto 4 is going to run like a "slow motion movie" if you don't reduce the graphic settings because Grand Theft Auto 4 is BADLY OPTIMIZED FOR THE PC.
The best thing you can do is upgrade your processor for playable FPS atleast.
Apparently the drivers on my gpu were outdated so after updating it improved a lot. Also went out and bought an amd phenom II X6 1045t six cores . That really made the trick. Now is really good with all the settings max. Thank you all for the replys
