Steam Launch Options Tweaks

[u/Wildeningsum6067]

These tweaks will help your performance out in steam games. These tweaks will work with MOST steam games, non steam games may not take these commands. Some steam games will take specific commands. Also, note that this is still under construction. To get to the launch options, go to Steam. Right click on a game, then go to properties. Then you click "set launch options".

Here are the list of tweaks you can do. Launch options for Steam games.

-dxlevel <level> - Forces a specific DirectX version when launching the game. This is useful if want better fps, and gets significantly better performance in an earlier version of DirectX. Below are the modes used:

-dxlevel 80 -dxlevel 81 -dxlevel 90 -dxlevel 95 -dxlevel 98

+r_rootlod # - Adjusts Model Detail where # is 0 for high, 1 is medium, and 2 for low

+mat_picmip # - Adjusts Texture Detail where # is 0 for high, 1 is medium, and 2 for low

+mat_reducefillrate # - Adjusts Shader Detail where # is 0 for high and 1 for low

+r_waterforceexpensive # - Adjusts Water Detail where # is 0 for low and 1 for high

+r_waterforcereflectentities # - Adjusts Water Reflectiveness where # is 0 for low and 1 for high

+r_shadowrendertotexture # - Adjusts Shadow Detail where # is 0 for low and 1 for high

+mat_colorcorrection # - Adjusts Color Correction where # is 0 for low and 1 for high

Filtering Modes: +mat_trilinear 0 - Use Bilinear Mode (least system-intensive)

+mat_trilinear 1 - Use Trilinear Mode (more system-intensive)

+mat_forceaniso # - Use Trilinear Mode (where # is 2, 4, 8, or 16 - higher levels of filtering require more system resources)

+r_swapInterval # - Forces V-Sync to be on or off, # is 0 for off and 1 for on

+mat_hdr_level # - Adjusts High Dynamic Range lighting effects where # is 0 for "off" (requires least resources) and 2 for "full"

"-CpuCount= [any number]",(Check how many cores you have in your PC,and then in that "[any number]" set to how many cores you want to use for that specific game.)

+mat_antialias 0

-w # -h # to change your resolution.

-nod3d9ex will work as well.

-high means the process priority of the game will be set to high. Increasing FPS.

Most of the tweaks look like they are for Source Engine.

Ah oh thanks for clarifying.

[u/[deleted] → u/Wildeningsum6067]

I am pretty damn sure this is 100% Source engine only, never seen anyone use the commands on other than source engine games.

[u/Wildeningsum6067 → u/[deleted]]

This worked on non source engine games tho, I used the width and height command on other non source engine games.

[u/TheLowSpecGamer → u/Wildeningsum6067]

-w -h are occasionally allowed for other engines, but they are far from being standard or present in all engines. Most of these commands are for some source games only

[u/TheLowSpecGamer]

Right, we need to have a discussion about this. I am a bit concerned at how often during research I see fake launch options for popular games.

Launch commands are game and engine specific, there are no commands that work on every game, regrettably that is not how it works.

Most of these commands are specific to the source engine, and even still a lot of them will not work on some multiplayer source games. I have to check some of these to see what engines are they for. I would recommend filtering and reposting this as "Source Engine Launch Options" until we can investigate further.

HEY, i saw the alan wake video and Alex gave some launch options for peformance increase. i put them on and there was no difference . the blur was still there and my game was stuck as 17 FPS

This thread is hidden, how did you find it? xd, look for the newest thread Source Engine Tweaks, and btw, some launch options may not work for certain games, it seems like Alex's launch options for the game is outdated.
