 -novid -high -lv -useallavailablecores

-novid

This option can save you a lot of time by disabling the intro video for left 4 dead 2. It is a great steam launch option for gamers who play a lot of games since it works on a lot of games from steam. Also, the intro video is quite loud and annoying to listen to every time you start the game.

-high

This steam launch option lets you play left 4 dead 2 in high priority settings. The same option works for a lot games so feel free to test this option in other steam games as well.

It saves you the time of manually using the task manager to increase priority of the game. Increased priority means more resources for left 4 dead 2 and higher FPS in gaming.

You can also optimize your system for gaming to boost FPS in Left 4 dead 2.

-useallavailablecores

This option forces the CPU to use all the cores for gaming. This option was originally meant for older games that were not used to the new multicore architecture. If you have an 8 core or a 16 core processor then this option can help you get some added performance in l4d2.

LV 

This command forces the game to launch is low violence mode. Hence the name -lv. It essentially enables the low-violence or censored version of the game where there is no blood and scary effects. The bodies also disappear quickly and scenes removal of limbs/cuts/wounds etc are removed. Burning effects, as well as blood splatter effects, are completely removed hence you get a great FPS boost and the cost of the scary experience. If you really need an FPS to boost then use this option otherwise don’t use it. It tends to take the fun out of the game.
That’s all folks. These were the steam launch options to boost fps in left 4 dead 2. If you guys know any more options that work well and do not cause vac ban issues as some options that have been excluded from the list do, then let me know in the comment section below. Happy Gaming
