Optimization Guide: 10x FPS Boost

Step 1 – Go to the game config folder

Open File Explorer and paste this into the address bar:
C:\Users%USERPROFILE%\AppData\Local\Chameleon\Saved\Config\WindowsIf the folder isn't there, launch the game once – it will be created automatically.

Step 2 – Create Engine.ini and paste the code

1. Right-click inside the folder → New → Text Document.
2. Rename it to Engine.ini (make sure file extensions are visible – Microsoft guide here[support.microsoft.com] if you need it).
3. Open Engine.ini file with Notepad, then paste this:
   [SystemSettings]
   ; ===== DISABLE LUMEN & RAY TRACING =====
   r.DynamicGlobalIlluminationMethod=0
   r.Lumen.DiffuseIndirect.Allow=0
   r.Lumen.Reflections.Allow=0
   r.RayTracing.ForceAllRayTracingEffects=0
   ; ===== STATIC LIGHTING & SHADOWS =====
   r.SSGI.Quality=0
   r.AmbientOcclusionLevels=0
   r.ShadowQuality=0
   r.DistanceFieldShadowing=0
   r.Shadow.MaxResolution=512
   ; ===== TEXTURE STREAMING (adjust based on your VRAM) =====
   r.Streaming.PoolSize=2048 ; Increase to 4096 if you have 6+ GB VRAM
   r.Streaming.MaxTempMemoryAllowed=512
   r.Streaming.LimitPoolSizeToVRAM=1
   r.Streaming.UseFixedPoolSize=1
   ; ===== FPS CAP (remove semicolon to enable) =====
   ; t.MaxFPS=144
   ; ===== ASYNC & THREADING TWEAKS =====
   r.AsyncCompute=0
   r.OneFrameThreadLag=0
   r.BatchSize=0
   r.EnableAsyncComputeOnEveryScene=0
   r.ShaderPipelineCache.Enabled=1
   ; ===== ANTI-ALIASING & SHARPNESS =====
   r.DefaultFeature.AntiAliasing=2
   r.TemporalAACurrentFrameWeight=0.75
   r.TemporalAASamples=16
   r.Tonemapper.Sharpen=0.5
   ; ===== STREAMING & LOADING OPTIMISATIONS =====
   r.Streaming.FullyLoadUsedTextures=0
   r.Streaming.HLODStrategy=2
   s.AsyncLoadingThreadEnabled=1
   s.AsyncLoadingTimeLimit=5.0
   s.LevelStreamingActorsUpdateTimeLimit=5.0
   s.UnregisterComponentsTimeLimit=5.0
   [SystemSettingsEditor]
   bInitializePhysicsOnCreation=1

Step 3 – Save and set to Read-only

• Save the file and close Notepad.
• Right-click Engine.ini → Properties → tick Read-only → OK.
  (This stops the game from deleting your file.)
• Launch the game. You should see a major FPS boost.
• To revert: delete Engine.ini.

❓ Troubleshooting

• Game crashes? Remove the [SystemSettingsEditor] section or delete the whole file.
• Blurry textures? Increase r.Streaming.PoolSize (4096 for 8 GB VRAM).
• Want a higher FPS cap? Remove the semicolon from t.MaxFPS and set your value.
  GPU crash dump ERROR:

1. Set very low ALL the graphic settings
2. Reduce resolution
3. Increase Windows pagefile size GUIDE [www.tomshardware.com]
4. Set Launch options in steam - write here -dx11 and -lowmemory
   That's it. Works on pretty much any system.
