Note: Although Mass Effect supports widescreen resolutions, some people may feel that it doesn't do so properly - e.g. Resolution has a noticeable impact on performance, so if nothing else works to improve your Frames Per Second (FPS), lower your resolution, or check the ScreenPercentage setting in the Advanced Tweaking section. The number of resolutions available is limited by what both your graphics card and monitor can handle. For more details see the Resolution section of the Gamer's Graphics & Display Settings Guide. The higher the resolution, the more detailed the image on screen, and also the less jagged lines there will be (See Antaliasing further below), but the lower your performance. Resolution: This setting allows you to select the resolution of the game image, measured in pixels wide by pixels high.

Gamma: This slider controls the overall brightness of the game, and has no performance impact, so set to suit your tastes.

Even at Low, the explosion and subsequent dust cloud seem quite satisfactory at Medium and High there's a slightly greater volume of dust and a brighter flash. In practice the performance impact between the three levels seems minimal, and as the screenshot comparison above shows, the visual difference is also not that great. The main performance impact of this setting is felt during combat, and in areas with large clouds of dust, fog or smoke. The available options are Low, Medium and High. Particle Effects: This setting controls the level of detail on particle effects - that is, special effects composed of smaller individual particles, such as smoke and explosions.
