This is especially useful to be able to see what a visleaf is rendering from diffrent angles.⤶ ⤶ - `r_novis 0/1`⤶ - Disabled the pvs system meaning the entire map will be drawn at all times⤶ ⤶ # Finding causes for lag⤶ Sometimes what is lagging the game isn't immediately recognizable so knowing how to find sources of lag for maps can be useful for optimization. ⤶ ⤶ for more indepth information read the [Dedicated Showbudget Wiki Page](https://developer.valvesoftware.com/wiki/Showbudget)⤶ ⤶ - `(+/-)showbudget`⤶ - Displays (+) or hides (-) the showbudget panel allow you to see a graph of what engine systems are being utilized the most.
