Apex Legends Optimization (2026): Maintaining Constant 144Hz

Apex Legends runs on a modified Source Engine. It loves CPU and hates particle effects. Master 'videoconfig.txt' to gain performance.

01.Introduction: The Source Engine at its Limit

Apex is resource-heavy. It renders massive maps using the Titanfall 2 engine. Default settings like "Volumetric Lighting" and "Sun Shadows" kill FPS.

In this guide, we'll modify the videoconfig.txt file to disable shadows that the in-game menu doesn't allow, ensuring visibility and high frames.

02.Chapter 1: In-Game Settings (The Basics)

Texture Streaming Budget

Recommended: None or Very Low (2GB)

This reserves VRAM for textures. If you set it to High (6GB) and your GPU has 6GB, the game will stutter when Windows needs VRAM. Leave it at None/Very Low to ensure you never run out of VRAM for the frame buffer. The textures might look ugly, but the game runs smooth.

Volumetric Lighting

Recommended: Disabled

Sunlight passing through dust. Beautiful, but it blinds you and eats 20 FPS. Turn it off.

Model Detail

Recommended: Low

Reduces the geometric complexity of distant objects. Essential for stability.

03.Chapter 2: videoconfig.txt (Shadow Hack)

The menu doesn't let you turn everything off. Let's edit the file:
%userprofile%\Saved Games\Respawn\Apex\local\videoconfig.txt

"setting.csm_enabled" "0" // (Disables sun shadows - Cascaded Shadow Maps)
"setting.csm_coverage" "0"
"setting.csm_cascade_res" "16" // (Minimum possible)
"setting.r_lod_switch_scale" "0.6" // (Reduces rendering distance for small objects)
"setting.bnao_enabled" "0" // (Disables Ambient Occlusion at low level)

Important: After saving, right-click the file > Properties > Check "Read-only". If you don't do this, Apex resets everything upon opening.

04.Chapter 3: Autoexec and Launch Options

In Steam/EA App > Game Properties > Launch Options:

-dev -preload -fullscreen -refresh 144 -forcenovsync
  • -dev: Removes the (loud) intro animation.
  • -preload: Attempts to pre-load assets into RAM (helps with HDDs, use with caution on systems with low RAM).
  • -refresh 144: Forces the Hz (change it to your monitor's).

Autoexec.cfg: Respawn blocked most cfg commands in 2021. Nowadays, cfgs focus more on binds (Superglide) than graphics.

A1.Chapter 4: DX12 Beta

Apex has launched support for DirectX 12 (Beta).
Add -eac_launcher_settings SettingsDX12.json to your launch options.
2026 Verdict: DX12 better utilizes multiple CPU cores. If you have an AMD GPU or RTX 4000 series and suffer from CPU bottlenecking, DX12 can increase your minimum FPS (1% lows) and make the game smoother, even though maximum FPS may not change much. It's worth testing.

A2.Chapter 5: Superglide and FPS Cap

Superglide is a movement mechanic that depends on FPS. It's easier to hit the timing with lower FPS.
Some pros lock their FPS to specific values (e.g., 144 or 180) via RivaTuner or the +fps_max 144 command to ensure movement consistency. Don't leave it unlimited if it fluctuates significantly.

A3.Chapter 6: Nvidia Reflex

As always, On + Boost.
Apex naturally has high system latency. Reflex is mandatory.
If you have AMD, enable Radeon Anti-Lag in the driver (there is no option in-game).

A4.Chapter 7: FOV and Performance

Almost every pro uses a FOV of 104 or 110.
High FOV = More peripheral vision, but enemies appear smaller (harder to aim) and FPS drops slightly (it renders more things).
If you can't see the enemy well, try lowering the FOV to 104 or 100.

Chapter 8: Audio (PC Equalizer)

Apex's audio is famous for being "broken" (silent footsteps).
Don't rely on the game. Use an external equalizer (Equalizer APO) to boost high frequencies (4k-8k Hz) where footsteps and reloads occur.

LEARN MORE

Chapter 9: Adaptive Resolution (FPS Target)

Apex has "Adaptive Resolution FPS Target." Set it to 0 (Off).
If you turn it on, the game will blur the entire screen whenever the FPS drops, making it impossible to aim. It's better to have FPS drops with a sharp image than to maintain FPS with a pixelated one.

Chapter 10: Temporary File Cleanup

Each season, Apex accumulates junk.
Perform a "Repair" of the game on Steam/EA App after every major update to verify file integrity and remove duplicate assets.

Frequently Asked Questions

Common questions answered by Voltris technical team

Q1.Stretched Resolution in Apex?

It works, but it's complex. Black bars appear unless you create a custom resolution in your GPU panel and use 'Autoexec commands' to force the aspect ratio. Many pros use 1680x1050 (16:10 stretched) for wider character models.

Q2.Bad microphone in Apex?

Apex's Voice Chat has a low-quality codec. Increase the 'Open Mic Threshold' so it doesn't pick up your mechanical keyboard, as the game's noise suppression isn't great.

Q3.DXGI_ERROR_DEVICE_HUNG crash?

This is usually unstable GPU overclocking or a bad driver. Remove any overclocking, roll back the driver to a stable 'Studio' version, or use Debug mode in the Nvidia Panel.
