Team Fortress 2 (TF2) is a first-person shooter PC game for Windows. Like the original Team Fortress game, it is a multiplayer game that lets you compete against each others in online teams. It is important to have a fast Internet connection for good performance in Team Fortress 2. However, this does not guarantee good system performance. The game's designer, Valve, recommends users have a 3.0GHz or faster Pentium 4 processor, 1GB RAM and a DirectX 9 video card to play the game. You can lower the graphics quality in Team Fortress 2 to boost performance if your computer does not have that powerful hardware.
Double-click the Team Fortress 2 icon on your Windows Desktop or the Start Menu to launch the game.
Click "Options" when the main menu loads. Navigate to the "Video" tab.
Lower the screen resolution using the drop-down menu under "Resolution." Selecting a lower resolution decreases the number of pixels your computer's video card must handle, increasing speed but lowering quality.
Click "Advanced..." for more graphics settings. At the top of the menu you should see six options: "Model detail," "Texture detail," "Shader detail," "Water detail," "Shadow detail" and "Color Correction." Disable "Water detail" and "Color Correction." Change the other settings to a lower level. You can set them to either "High," "Medium," or "Low."
Navigate down the menu and turn "Antialiasing mode" off or to a lower level. Do the same for "Filtering mode" and disable "Wait for vertical sync." Turn "Motion Blur" and "High Dynamic Range" off as well. Make sure "Use 'bloom' effect when available" is unchecked.
Adjusting the above settings should substantially decrease the graphics quality and boost performance, especially on older computers. If this is not enough, you can also decrease "Field of view" from the "Advanced..." menu. This essentially reduces your line of sight and thus decreases the level of detail your computer must process.
Press "OK" to apply the new changes on the "Advanced..." menu. Press "OK" again on the main "Options" menu to apply all the changes.
