fronzelneekburm: Feel free to let me know how it runs on your laptop, I'm curious! It ran like shit on my 10 years old PC, likewise on my 5 years old laptop and kinda barely runs adequately on my fairly recent machine. I haven't tried any mods yet, since I figured I might as well try all the games I bought during the past decade that I hadn't tried before and that run well out of the box.
Here is the GTA IV benchmark results on my old ASUS G75VW gaming laptop (using the graphics options that the game suggested, and vsync off):

During the gameplay though, without vsync the framerate did seem to dip a little bit under 30 fps at some points. I'd say the game was running at around 24-75 fps depending what was on the screen. I didn't try to change the graphics options to see how much they'd affect it.
With vsync on, it would fluctuate between 60 and 30 fps.
However, it runs considerably better than what I was expecting, considering the age of my PC. For this type of game, I consider it quite playable, so I might actually start playing it now while I'm at it (I played until the First Date; I managed to kill my date (Michelle) in a freak "accidentally drive the car into a 4-feet deep pool in a park while trying to find a way out of the park"-accident, Michelle drowned. :(
In a fast online shooter like Team Fortress 2, constant 60 fps is much more important to me than this kind of "driving/walking simulator" with sluggish controls.
It is interesting though that from what you said, it appears the GTA IV will not run considerably better on more powerful hardware? Or what were your graphics settings, everything at max (draw distance etc.)? Maybe I will also try how GTA V runs on this same old PC.
