Stutter Fix and Smoother FPS

Beginning

As you have noticed, The Callisto Protocol suffers from a stutter related to texture streaming and shader cache. This is a common issue across UE4 games. You have probably noticed a similar issue if you have played

Borderlands 3,

Star Wars Jedi: Fallen Order,

Remnant: From the Ashes

But lets get to the point, the fix.

Engine.ini Edits For Fix

I have negated most of the games stutter by applying the same fixes I used for the previous 3 titles.

Navigate to the games config folder

\AppData\Local\CallistoProtocol\Saved\Config\WindowsNoEditor

Once here open up Engine.ini

At the end of Engine.ini paste the following

[/script/engine.renderersettings] niagara.CreateShadersOnLoad=1 r.CreateShadersOnLoad=1 D3D12.PSO.DiskCache=1 D3D12.PSO.DriverOptimizedDiskCache=1 r.HZBOcclusion=0 r.AllowOcclusionQueries=1 r.Shaders.Optimize=1 [TextureStreaming] r.Streaming.Boost=1 r.Streaming.FullyLoadUsedTextures=1 r.Streaming.HLODStrategy=2 r.bForceCPUAccessToGPUSkinVerts=True r.Streaming.FramesForFullUpdate=60 r.Streaming.DropMips=0 r.Streaming.LimitPoolSizeToVRAM=0 r.Streaming.MipBias=0 r.Streaming.UseAllMips=1 r.Streaming.UseMaterialData=1 r.Streaming.UseNewMetrics=1 r.Streaming.UsePerTextureBias=1 r.Shaders.Optimize=1 r.Shaders.FastMath=1 r.UseShaderCaching=1 r.UseShaderPredraw=1 r.UseAsyncShaderPrecompilation=1 r.TargetPrecompileFrameTime=13 r.PredrawBatchTime=13 r.AccelPredrawBatchTime=0 r.AccelTargetPrecompileFrameTime=0 r.Streaming.DefragDynamicBounds=1 s.AsyncLoadingThreadEnabled=True r.Streaming.PoolSize=0 [ConsoleVariables] AllowAsyncRenderThreadUpdates=1 AllowAsyncRenderThreadUpdates=1 AllowAsyncRenderThreadUpdatesDuringGamethreadUpdates=1 AllowAsyncRenderThreadUpdatesDuringGamethreadUpdates=1 AllowAsyncRenderThreadUpdatesEditor=1 AllowAsyncRenderThreadUpdatesEditor=1 s.AsyncLoadingThreadEnabled=True

These are tweaks used across UE4 games that help get rid of the stutter.

One thing to note is, these tweaks also cause the game to load the shaders before gameplay, which will result in slightly longer load times

Additional Changes

Launch options

I used the same launch option I used for Remnant.

-dx12 -xgeshadercompile

Now that the Stutter is mitigated. Lets talk about the drops.

The games FPS drops are a different issue, these can't just be solved by editing the Engine.ini

Here are my settings to smooth the game out and help get rid of the drops. (Apply in menu)

Max FPS = 60 (I also applied this in nvidia control panel)

^ The game on my system ran at around 120-144 fps unlocked with no ray tracing. But the performance is so unpredictable that it randomly dropping to 40fps from 120 is extremely noticeable. Keeping this locked at 60 makes dips less apparent.

Motion Blur = OFF

^ While some people actually like motion blur in games, enabling it on a game with fps dips makes it look way worse as it will dip while the screen is blurred.

Set Upscaling to AMD FSR 2 to performance

^ While FSR seems to be completely broken for some people atm, this works well if it happens to work for you. You can also try disabling it as some have reported success with that

Render mode = DX12

^ This provided the best FPS on my system. Although some have reported better stabillity on DX11. Since DX12 performance is vastly different on different hardware, its worth running a benchmark on both to see losses/gains. (Just note, DX11 disables some settings.)

Summary And Credits

Thanks to the community for finding the best in-game settings.

I hope this helped smooth out your game and experience.

Sorry for badly formatted guide, not sure how to use steams formatting very well.

Post Publish Edit: The Callisto Protocol's twitter posted that there is a patch for stuttering coming today. As well as further updates down the line for it. Once that update is published take this guide with a grain of salt, although it may still help.
