Final answer:
To disable the frame rate limit, you can use the listed commands as launch options, with the understanding that hardware and monitor refresh rate limitations may prevent reaching the desired high frame rates. Always ensure that your system can handle the increased load of uncapped frame rates.
Step-by-step explanation:
To disable the frame rate limit on a piece of software or a game, the commands you've listed are typically used as launch options if the software supports them. For example, these flags can be set in the properties of a shortcut to a game or directly within a game's launch options if it's on a platform like Steam. However, using such high values like "9999 fps" is impractical, as most monitors cannot display beyond a certain frame rate due to their refresh rate limitations, and the hardware itself might not be able to render at such high frame rates. Furthermore, disabling VSync (--disable-gpu-vsync) can sometimes lead to screen tearing where multiple frames are displayed at once. The flag --disable-frame-rate-limit is intended to remove the cap on the frame rate imposed by the application.
To proceed, you need to find the executable file of the application or the shortcut you use to launch the game. Right-click on it and choose properties, then look for a field like 'Target' where you can add the commands after the path to the executable, usually outside of the quotation marks. Note that not all applications or games support these commands and doing this may not have any effect or could potentially lead to stability issues. Always make sure that your hardware can handle the increased load when you uncap or raise the frame rate limit.
