Call of Duty: Modern Warfare 3
Call of Duty: Modern Warfare 3 was released in 2011 and runs in DirectX 9, which is noteworthy as most PC titles around this time supported DirectX 11. Performance and visual quality are of a disappointing standard.
Version Differences
Modern Warfare 3 uses Steamworks, meaning all versions of the game including those from retail and digital distribution channels all require and register on Steam.
Graphical Tweaks
Field of Vision (FOV) Fix
- FOV Changer - Can adjust your field of view well beyond the game's default of 65. Thus far use has not resulted in a VAC ban for users.
Native vs Extra Image Quality
Set Image Quality to "Native", as "Extra" upscales the textures resulting in poor image quality.
Widescreen Fix
- Widescreen Fixer - Modern Warfare 3 is reported to cooperate well with this application.
DirectX 9 Compatibility With Older Video Cards
- "-dx9" in the launch options will force DirectX 9 compatibility mode.
- "seta rRendererPreference "Shader model 2.0"" in the player config for single player or multiplayer respectively.
