Fallout 3: Game of the Year Edition System Requirements

If your PC meets the minimum requirements (2.4 GHz Pentium 4 or equivalent, 256MB NVIDIA 6800/ATI X850, 1GB RAM), you should be able to run the game at lower settings. Expect lower frame rates and potential stuttering.

At a minimum, you'll need a DirectX 9.0c compliant video card with 256MB of RAM, such as an NVIDIA 6800 or ATI X850. For better performance, an NVIDIA 8800 series or ATI 3800 series with 512MB RAM is recommended.

The game requires a minimum of 1GB of RAM. However, 2GB of RAM is recommended for a smoother experience, especially with higher settings and mods.

It's unlikely that Fallout 3 will run well on most integrated graphics solutions from the time of its release. Integrated graphics typically lack the dedicated memory and processing power required for the game, even at the lowest settings. You may experience very low frame rates or be unable to run the game at all.

The 'best' settings depend on your hardware. If you meet the recommended specs, try high settings. If you meet the minimum, start with medium or low and adjust upwards until you find a balance between visual quality and performance. Pay attention to draw distance and shadow quality, as these heavily impact performance.
