4.Implement Apex Legends Launch Options

Utilize Steam or Origin/EA App launch options to apply critical commands before the game even starts, overriding some in-game settings for maximum performance.

  • Add Performance Launch Commands High impact

    In Steam (Game Properties > General) or EA App (Game Properties > Advanced Launch Options), add: `+fps_max unlimited -dev +cl_showfps 4 -forcenovsync`. This removes the FPS cap, enables dev mode for better performance, shows FPS, and forces no V-Sync.

  • Set High Priority for Apex Legends Medium impact

    While not a launch option, set Apex Legends to 'High' priority in Task Manager after launching the game. This ensures Windows prioritizes game processes.

  • Consider `-novid` for faster startup Low impact

    Add `-novid` to your launch options to skip the intro videos, getting you into the game faster. This doesn't directly boost FPS but improves the user experience.

5.Optimize In-Game Video Settings

Adjusting Apex Legends' internal video settings is paramount. For competitive play, prioritize performance over visual fidelity, even with an RTX 4090.

  • Lower Texture Streaming Budget Medium impact

    Set 'Texture Streaming Budget' to 4-6GB. While your RTX 4090 has abundant VRAM, lower settings can reduce load and improve 1% lows.

  • Disable Adaptive Supersampling High impact

    Ensure 'Adaptive Supersampling' is disabled. This setting dynamically lowers resolution to maintain FPS, which is unnecessary and detrimental to visual clarity on an RTX 4090.

  • Reduce Model Detail and Impact Marks High impact

    Set 'Model Detail' to Low and 'Impact Marks' to Low or Disabled. These have a noticeable impact on CPU and GPU performance during intense fights.

  • Turn Off Advanced Visual Effects High impact

    Disable 'Spot Shadow Detail', 'Volumetric Lighting', and 'Ambient Occlusion'. These are graphically intensive and offer little competitive advantage.

Recommended Apex Legends settings

Setting Recommended value Why it matters
Display Mode Full Screen Full Screen mode bypasses the Desktop Window Manager, reducing input lag and improving performance stability.
Adaptive Resolution FPS Target 0 (Disabled) Disabling this prevents dynamic resolution scaling, ensuring consistent visual quality at your native resolution with the RTX 4090.
Texture Streaming Budget 4-6 GB Even with 24GB VRAM on the RTX 4090, setting this lower can reduce VRAM pressure and improve 1% lows, especially in CPU-bound scenarios.
Model Detail Low Reduces the complexity of character and object models, significantly impacting CPU and GPU load during combat.
Impact Marks Disabled Turning off bullet impact marks reduces visual clutter and frees up GPU resources, especially during prolonged firefights.
Ragdolls Disabled Disabling ragdoll physics reduces CPU overhead when players are eliminated, preventing potential stutters.
Spot Shadow Detail Disabled Shadows are computationally expensive. Disabling spot shadows provides a noticeable FPS boost without significant competitive disadvantage.
Anti-aliasing TSAA TSAA offers a good balance between visual smoothness and performance. Avoid higher settings like MSAA if available, as they are very demanding.

Common mistakes to avoid

  • Running background applications (browsers, Discord overlays, streaming software) that consume CPU/GPU resources.
  • Not regularly updating GPU drivers or performing 'Express' installations instead of 'Clean' ones.
  • Leaving V-Sync enabled, which introduces input lag and caps FPS to your monitor's refresh rate.
