Steam Console: Ultimate +launch_options Master List 2026

Launch options are parameters added to a game’s startup string. To use them, right-click any game in your Steam Library, select Properties, and find the Launch Options box under the General tab. Always separate commands with a single space.

Technical Configuration (The 2026 “Performance & Logic” Template)

For a universal “Competitive Start” that works across most Source-based and modern titles, use this string:

-novid -high -nojoy -tickrate 128 +fps_max 0 +cl_forcepreload 1

Universal Core Commands (General Use)

Command	Function	2026 Use Case
-novid	Skips Valve/Publisher intros.	Saves 5-10 seconds on every boot.
-high	Sets CPU priority to “High.”	Prevents background apps from causing stutters.
-nojoy	Disables controller support.	Frees up a tiny amount of RAM/CPU cycles.
-console	Enables developer console.	Essential for real-time troubleshooting.
-refresh [Hz]	Forces monitor refresh rate.	Ensures you aren’t stuck at 60Hz on a 240Hz screen.
-fullscreen	Forces Exclusive Fullscreen.	Best for lowest input latency.

Advanced Engine Overrides (FPS & Networking)

These commands interact directly with the game’s internal variables (+ commands) rather than just startup flags (- commands).

• +fps_max 0: Removes the frame rate cap entirely. Note: If you have a G-Sync monitor, it is better to set this to 3 below your refresh rate (e.g., +fps_max 141 for 144Hz).
• +thread_pool_option 0: (New for 2026) Forces the engine to prioritize Performance Cores on hybrid CPUs (Intel 13th-16th Gen), preventing the game from accidentally running on low-power E-cores.
• -mainthreadpriority 2: Elevates the main game logic thread to high priority without affecting other system tasks.
• -vulkan: Forces the game to use the Vulkan API. This is often faster on AMD cards and Linux/Steam Deck but should be tested against DX12 for stability.
• -allow_third_party_software: Required if you use OBS Game Capture or RivaTuner overlays in games with strict anti-cheats (like CS2).

Strategy for 2026 System Optimization

• The “Less is More” Rule: In 2026, many developers (including Valve) suggest using fewer launch options. If a command like -threads is used incorrectly, it can actually lower performance by interfering with the OS’s native thread scheduling.
• Autoexec Integration: Instead of cluttering your launch options, use +exec autoexec.cfg. This tells Steam to run a separate script file where you can store hundreds of lines of technical tweaks cleanly.
• DirectX Enforcement: If an older game crashes on Windows 11/12, use -dxlevel 90 or -dxlevel 101 to force a specific API version that the game was originally designed for.
• Shader Pre-caching: While +cl_forcepreload 1 helps on older systems, modern NVMe SSDs usually handle loading fine. If you experience “Loading Screens” that never end, try removing this command first.

Conclusion and Expected Results

By applying a tailored list of +launch_options, you are bypassing the “safe” defaults set by developers and forcing your hardware to perform at its limit. You can expect faster boot times, stable frame pacing, and minimized input lag across your entire Steam library.
