"Before we get into the review any further, let me just state that if you are one of the many who had issues with Grand Theft Auto 4 running on your PC then this is one you will certainly want to avoid. I have a Quad Core Intel CPU running at 3ghz with 2 GB of ram and even on my 9800 GTX the game struggles to maintain a good frame rate at a high resolution. I was getting performance around the 15-20 fps mark which I don't think is particularly acceptable in 2009 for such a decent gaming PC. Clearly developers recently feel we should all be running Skulltrail with 3 280 GTXs in SLI to get acceptable performance from our console ports!"

"You’d think that the benefit of less-than-cutting-edge graphics would be a smooth frame rate, but in this case you’d be wrong. I couldn’t get the game to reliably run at more than 15 to 20 frames per second while driving around the city on high-end hardware, and bizarrely, it wasn’t significantly better even when set to low detail at 800x600 resolution. Even on high settings cars don’t look great, and AI-controlled vehicles frequently vanish even while you’re looking directly at them. It also doesn’t support common widescreen resolutions like 1680x1050 or 1920x1080. The next most-noticeable port issue is the lack of mouse controls for the menus - not an issue if you plug in a gamepad, but in a game with this much free-aim shooting that’s hard to recommend."
