Grand Theft Auto IV: The Complete Edition System Requirements

Potentially, but it depends on your definition of 'low-end'. You'll need at least an Intel Core 2 Duo 1.8GHz or AMD Athlon 64 X2 4000+, a NVIDIA GeForce 7900 256MB or ATI Radeon X1900 256MB, and 2GB of RAM to meet the *minimum* requirements. Expect to play at lower settings and resolutions.

At a minimum, you'll need a NVIDIA GeForce 7900 256MB or an ATI Radeon X1900 256MB. For a better experience, especially at higher settings, an NVIDIA GeForce 8600 512MB or ATI Radeon HD 3870 512MB is recommended.

The game requires a minimum of 2GB of RAM. However, the recommended amount is 2.5GB. While not a huge jump, having more RAM can improve stability and reduce stuttering.

It's unlikely to run well, if at all, on most integrated graphics solutions. The game requires dedicated graphics cards with at least 256MB of VRAM. Integrated graphics typically share system memory and are not powerful enough for this game.

There isn't a single 'best' setting, as it depends on your hardware. Start with medium settings and adjust from there. Pay close attention to draw distance, texture quality, and shadow quality, as these have the biggest impact on performance. Experiment to find a balance between visual quality and smooth gameplay.
