Fallout 3 is based on the same engine used by The Elder Scrolls IV: Oblivion, and it is a DirectX 9.0c (Shader 3.0) game. We configured the game with “low” image quality settings at 1440×900. To measure performance, we used the FRAPS utility utility running an outdoor scene at God mode, running through enemy fire, triggering post processing effects, and ending with a big explosion in front of Dupont Circle.
The integrated video from Core i5-661 could not run this game.
Comparing the results with a GeForce 9600 GT installed, all CPUs achieved the exact same performance level.
