So you've heard about Steam launch options but aren't quite sure what they do or why you'd bother? I was exactly there a few years back. Honestly thought they were some developer-only tools until my favorite game kept crashing on startup. That's when I discovered how steam set launch options can literally save your gaming experience.
Launch options are basically secret commands you feed to games before they start. They're like giving your game a special set of instructions - maybe telling it to run in windowed mode, use a specific graphics card, or skip those annoying intro videos. Simple concept, massive impact.
Why Steam Launch Options Actually Matter
Let's cut the hype - launch options won't magically turn your potato PC into a gaming beast. But what they can do? Fix stubborn crashes, squeeze out extra FPS, and bypass annoying game behaviors. I remember struggling with Rainbow Six Siege's Vulkan API crashing every launch until I added -vulkan to the steam set launch options. Fixed instantly.
Main reasons gamers use them:
- Force specific graphics APIs (-dx11, -vulkan) when games default poorly
- Disable intro videos that can't be skipped (-novid)
- Allocate more VRAM for texture-heavy games
- Override automatic resolution detection
- Enable developer consoles for troubleshooting
- Fix fullscreen bugs that alt-tab haters despise
Heads up: Used incorrectly, launch options can break games completely. I learned this the hard way when I pasted a complicated command I found online and couldn't launch Skyrim for two days. Always test one option at a time!
Where to Find and How to Set Steam Launch Options
This isn't hidden deep in config files - Valve actually gives you an easy way to set these. Here's exactly where to go:
- Open your Steam client (the desktop app, not browser version)
- Navigate to your Library tab
- Right-click the game you want to modify
- Select "Properties" at the bottom
- In the new window, find the box under "Launch Options"
That empty box? That's where the magic happens. Type your commands directly into that field. Each command starts with a hyphen and you separate multiple commands with spaces.
Pro Tip: Steam sometimes removes your launch options after game updates. Annoying, but just re-add them. I wish Valve would fix this - it's been happening for years.
Essential Launch Options Every PC Gamer Should Know
These are the workhorses I've used across dozens of games:
| Command | What It Does | Games Where It Works | My Experience |
|---|---|---|---|
| -novid | Skips intro videos (Ubisoft logo, etc.) | Most AAA titles (Assassin's Creed, Far Cry) | Massive time saver but occasionally prevents cloud saves |
| -windowed | Forces windowed mode at launch | Games with broken fullscreen (older Bethesda titles) | Combine with -noborder for borderless window |
| -console | Enables developer console (usually ~ key) | Source engine games (CS:GO, Portal 2) | Essential for troubleshooting but clutters screen |
| -high | Sets game to high CPU priority | CPU-intensive games (Cities: Skylines) | Minor FPS boost but can make system sluggish |
| -w 1920 -h 1080 | Forces specific resolution | Games that default to wrong resolution | Works 90% of time when display settings fail |
| -tickrate 128 | Sets server tick rate (CS2 only) | Counter-Strike 2 | Must-have for competitive play |
Advanced Performance Tweaks
These require caution but can yield serious gains:
- -malloc=system - Uses system memory allocator (helps Rust)
- -maxMem=16384 - Caps RAM usage at 16GB (prevents leaks)
- -disablehangwatchdog - Stops auto-crash on freeze (risky!)
Personally avoid most VRAM commands - they often cause more problems than they solve. Modern games manage VRAM better than we give them credit for.
Game-Specific Launch Options That Actually Work
Generic commands help, but real magic happens with game-specific options. Here's what's consistently worked across my library:
Counter-Strike 2 Launch Options
The competitive standard:
- -freq 144 (matches monitor refresh rate)
- -novid -console -tickrate 128
- -nojoy (disables joystick support for cleaner inputs)
Notice no FPS boosters here? Most are placebo. Valve's John McDonald confirmed many don't work in CS2.
Skyrim Special Edition
Essential for modders:
- -forcesteamloader (fixes SKSE loader issues)
- -alttab (solves alt-tab crashes)
- -windowed -borderless (borderless window mode)
Skip memory patchers - modern SKSE handles this better.
Apex Legends
Actual useful commands:
- +fps_max unlimited (removes 300 FPS cap)
- -dev -preload (faster loading times)
- +m_rawinput 1 (raw mouse input)
Ignore "performance boost" commands - Respawn disabled most.
Cleaning Up Launch Option Messes
Ever added too many commands and broke everything? Join the club. Here's how I troubleshoot:
Step 1: Remove ALL launch options
Step 2: Verify game files through Steam
Step 3: Add commands back ONE at a time
Step 4: Test launch after each addition
Common conflicts I've encountered:
- Resolution commands fighting with in-game settings
- API overrides (-dx12) causing crashes on unsupported hardware
- Outdated commands from forum posts circa 2015
When Cyberpunk 2077 kept crashing after patch 1.5, turns out my old -skipStartScreen command was the culprit. Removed it and smooth sailing.
FAQ: Steam Set Launch Options Demystified
Do launch options affect multiplayer?Most don't - but avoid anything starting with +sv_ or +mp_ which could trigger anti-cheat. Performance tweaks are generally safe.
Why won't my Steam set launch options save?Steam Cloud sometimes overwrites them. Disable cloud saves for that game temporarily. Also check if you're editing the correct game - I've mixed up games with similar names before.
Can launch options damage hardware?Not physically, but forcing settings like -maxMem beyond your RAM capacity causes crashes. No permanent damage though.
Best source for game-specific commands?PCGamingWiki beats random forums. Their commands are tested and version-controlled. Reddit threads often suggest outdated or placebo commands.
Do these work on Steam Deck?Exactly the same! Access through Properties in Gaming Mode. Proton versions affect compatibility though.
The Launch Option Commandments (From My Experience)
- Always test commands individually before combining
- Document changes - you WILL forget what you added
- Delete all options after major game updates
- Avoid "performance packs" - 90% are snake oil
- When in doubt, -safe mode usually works
Last thought? Launch options are powerful but not mystical. They won't fix bad hardware or poorly optimized games. But when that one command finally makes your favorite game run smooth? Chef's kiss. Totally worth the tinkering.
Honestly, I'd love to hear if you've discovered any rare gems - hit me up on Reddit with your favorite steam set launch options tricks. Still hunting that perfect Elden Ring stutter fix myself...
