MWLL Performance Guide

Since MWLL is built off of the original Crysis engine, massive intense battles may occasionally slow your FPS on an older low to mid range computer or laptop as Crysis doesn't take advantage of using multiple CPU cores. However, by using the preset performance optimized user.cfg available below and then optionally turning off shadow rendering with the F4 key, you can enjoy a relatively smooth MWLL experience.

A modern Ryzen 5000+ or Intel 12000+ series non-mobile CPU will be able to deliver 60+ FPS most of the time with the default MWLL settings.

TL;DR: For best stability and performance while keeping high visual fidelity, run at 1080p (1920x1080) or lower resolution and select one of the three (HQ/Balanced/Performance) user.cfg files mentioned below.



User.cfg is the file that provides fine-grained control over the graphical quality of MWLL. The three downloadable user.cfg files below contain settings that improve the visual quality of the game while also increasing performance over Crysis's stock graphics settings. The optimized balanced user.cfg increases FPS close to Crysis Medium settings but with quality of Crysis High settings while increasing shadow rendering distances. Performance optimized user.cfg slightly reduces object quality and shadow rendering distance while HQ user.cfg increases them.

It is placed in the C:\Users\[username]\Documents\My Games\Crysis Wars\MWLL\Client directory. (Replace username and/or drive name with your current Windows username / Windows installation drive.)

Alternatively, you can browse to the correct folder by copy/pasting this into your Explorer window: %USERPROFILE%\Documents\My Games\Crysis Wars\MWLL\Client

NOTE: The user.cfg files all disable Crysis's native full screen antialiasing and instead rely on the native edge antialiasing instead. Crysis's Full screen antialiasing (FSAA) consumes more memory which may cause crashes on larger maps, can cause minor texture corruption, can cause issues while switching between full-screen and windowed modes and it can be FPS heavy. If you really want better antialiasing, consider using Reshade's SMAA.

The user.cfg files below all feature mapped function keys that toggle a few key settings:

  • F4 toggles shadow rendering (disabling all shadows will increase FPS)
  • F9 toggles Shader post processing (Very slightly increases FPS but some maps look dull / desaturated with it disabled, removes depth of field blur effect while zooming, removes god-rays and shimmering underwater effects)
  • F10 toggles Crysis's FPS counter
  • F11 toggles net_channelstats - use to diagnose red-x / lossy connection to servers. Details how to use it are found here: Net_channelstats
  • PAUSE toggles HUD - for screenshots

The user.cfg config files have been changed significantly. If you're running the previous versions, please update to these for increased FPS overall.

They all include these tweaks:

  • Allow all lighting effects (dynamic and static) on all maps.
  • HDR rendering is enabled for proper lighting/brightness on all maps - avoids over-bright rendering.
  • Edge anti-aliasing enabled for less jaggies.
  • Increased FPS by reducing the water effect quality a bit.
  • Increased FPS by shortening the decal effects lifetime - laser burn effects disappear more quickly.
  • Increased FPS by disabling distant static object dissolve render effect.
  • Full screen antialiasing (FSAA) disabled - can cause minor texture corruption.

  • Highest quality visuals and good performance Preset - Updated August 2023 (right-click > Save link/file)
    • Set for highest quality visuals. Better FPS than stock Crysis High settings yet comparable high quality effects.
      • Longer shadow draw distances with more real-time shadows cast from terrain and objects.
      • Screen Space Ambient Occlusion enabled for more realistic lighting effects.
      • Optimized particle and texture settings - balanced for visuals and FPS.

  • Balanced quality vs performance preset - Updated August 2023 (right-click > Save link/file)
    • Set for balanced quality visuals. FPS almost as fast as stock Crysis Medium settings but with considerably improved visuals.
      • Medium shadow draw distances and keeps shadows cast from terrains on.
      • Screen Space Ambient Occlusion enabled for more realistic lighting effects.
      • Optimized particle and texture settings - leans towards better performance.
      • Increased FPS by reducing distant level of detail rendering for static objects.

  • Best performance optimized preset - Updated August 2023 (right-click > Save link/file)
    • Set for performance oriented visuals. FPS around stock Crysis Medium graphics settings while looking a lot better (avoids opaque water bug).
      • Low shadow draw distances.
      • Screen Space Ambient Occlusion disabled.
      • Performance optimized light, particle, decal and texture settings.
      • Increased FPS by further reducing distant level of detail rendering for static objects.

The Settings Menu


We recommend to use 1080p (1920x1080) as the highest resolution for maximum game stability. Higher resolutions such as 1440p (2560x1440) or 4k (3840x2160) may increase the chance of the game crashing to desktop (CTD) and will require a faster, more modern CPU and GPU to achieve smooth FPS.

It is strongly suggested that you do NOT change the settings in OPTIONS / SYSTEM SETTINGS / GRAPHICS / ADVANCED from their defaults. MWLL ships with pre-configured optimal medium settings that have combined performance and visual tweaks to give you more FPS in intense graphics heavy battles. Do not use the "Autodetect - Optimal Settings" as they will remove the optimizations until the next restart.

The Crysis engine that MWLL is built on requires a CPU that has high single thread performance to deliver high FPS. Recent AMD Ryzen 3000/5000 and Intel CPUs Haswell and later series with 3 GHz base clock or faster are recommended while the best performance will be achieved on a Ryzen 5800 X3D, Ryzen 7000 series or Intel 13600+ series.

Crysis doesn't require a high-end GPU for smooth 1080p (1920x1080) gaming. Any AMD RX460 or GTX 1030 or newer GPU will be fine for the pre-configured optimal settings.

The quickest way to reclaim FPS on older hardware or if your machine lacks a discrete graphics card are:

  • Reducing your in-game resolution and disabling any multi-GPU setups (Nvidia SLI, AMD CrossFire, or Nvidia Optimus). After finding your monitor's native resolution, try to reduce your resolution to some lower setting of the same ratio. Anecdotally, some users find a performance spike by selecting a resolution that's a half multiple of their native resolution (for example; 1920 x 1080 -> 960 x 540). The FPS gains made by lowering your resolution will only be more pronounced if your machine lacks a discrete graphics card.
  • Setting in-game Anti-Aliasing Quality to OFF found in OPTIONS / SYSTEM SETTINGS / GRAPHICS. The MWLL pre-configured optimal settings already have Crysis's FPS friendly edge anti-aliasing enabled by default. Crysis's Full screen antialiasing (FSAA) consumes more memory which may cause crashes on larger maps.

Advanced Settings


We strongly recommend that you don't alter these settings as they will possibly disable the MWLL pre-configured optimizations. If absolutely needed, reducing the following settings might increase your FPS.


For higher FPS while keeping the MWLL optimizations, we highly recommend to utilize the user.cfg - specifically, the "Best performance optimized preset - Updated August 2023" preset mentioned above.


It is advised that on your first launch, that you reduce the in-game sound somewhat and bring it up to a comfortable level afterwards as the defaults may be too high. Performance wise, there is functionally no gains to be made by playing with settings in the Sound menu.

Outdated CFGs

WARNING! The following user.cfg files are out of date and have a bunch of bugs that causes some settings to be set to the highest possible setting (ie sys_spec_Shadows = 0 sets *all* shadows to the max and killing performance). Only use them if you are willing to edit the file yourself to fix the bugs and change/experiment with the necessary config settings at your discretion to meet your preferences.

There are multiple bugs in the following user.cfgs! DO NOT USE THEM WITHOUT CAREFULLY ANALYZING THEM! At the minimum, change the following:

  • sys_spec_Shadows = 0 should be sys_spec_Shadows = 1 .
  • Deleting the line e_particles_quality = 9 or ingame projectiles will become invisible.
  • Deleting the line d3d9_forcesoftware = 1, or the ingame Console and Cbill Transfer Menu will be unusable due to invisible text
  • Deleting the line e_particles_max_emitter_draw_screen = 0, or too many particles will be shown on certain maps and perf will tank.

Shader Cache cleanup

If you normally have adequate performance, but lose it seemingly out of the blue: use the Clear Shaders option from the MWLL Launcher. MWLL Shaders have a gamut of interesting bugs tied to them, from hidden performance sinks to rainbow clouds and pink hovercraft dust- but it's easily fixed in the click of a button.

Other Options

If you are still having trouble getting the performance you're looking for, consider joining the MWLL Discord and inquiring in the #tech_support channel for more assistance.

Besides that, the following are a few more options that can increase stability and performance, but have to be approached with a trial-and-error mindset, considering each player's mix and match of these settings may not work for another player's system.

  • Running the game in DX9 instead of DX10 mode from the launcher
  • Running the game in Windows Compatibility mode for Windows 8, Windows 7.1 (Can be found by right-clicking the launcher, and opening 'Properties')

These, and a few more steps can be found in the Troubleshooting Guide
