Modify FOV using a console[citation needed]
|
- Press ~ and the in-game console will appear.
- If it does not appear, go to Game Options and make sure the console is enabled.
- In order to permanently change the FOV, write the command
seta cg_fov XX , where XX is the desired horizontal field of view (e.g. seta cg_fov 90 ). The command "seta" permanently writes commands following it to the config.
Notes
- Weapon models are affected by changes in FOV.
|
Enable windowed mode using console[citation needed]
|
- Press ~ and the in-game console will appear.
- If it does not appear go to Game Options and make sure the console is enabled.
- In console, type in
/r_fullscreen 0 to enable windowed mode (or /r_fullscreen 1 to enable fullscreen mode) and press ↵ Enter.
- Type in
/vid_restart and press ↵ Enter to restart the game's renderer and apply new settings.
|
Change seta r_fullscreen "1" to seta r_fullscreen "0" in config.cfg [citation needed]
|
Unlock frame rate[citation needed]
|
- Enable console in options.
- Press ~.
- Type
/com_maxFPS # where # is the preferred frame rate cap.
Notes
- In order for the fixes to work, Vsync needs to be turned off from the game's settings if the screen's refresh rate is less than the required FPS. The setting for Vsync is listed as "Sync Every Frame" under the Graphics tab in the game Options and needs to be set to "No".
- Some servers do not allow having a frame rate above 250 due to possible cheating.
- High frame rates can influence aspects of the game's mechanics (such as jump height), and this weakness of the engine is exploited by some players to gain an advantage.
