SoulCalibur VI: Best Engine.ini for Unreal Engine 4 Physics

The primary goal is to minimize Input Latency and prevent the “Fake Frame” delay built into the engine, allowing for a 1:1 response between your controller and the physics simulation.

File Path & Access

File Path: %LOCALAPPDATA%\SoulcaliburVI\Saved\Config\WindowsNoEditor\

Step-by-Step Instructions:

1. Press Win + R, paste the path above, and press Enter.
2. Locate the file named Engine.ini. (Backup the file as Engine_Backup.ini before editing).
3. Right-click the file and open it with Notepad.
4. Paste the technical block provided below at the very bottom.
5. Note: For visual clarity, we also recommend adding a line to Scalability.ini (see Best Practices).

Optimized “Physics-Priority” Configuration Block

[SystemSettings]
r.GTSyncType=1
r.FinishCurrentFrame=0
r.Shaders.Optimize=1
r.Streaming.PoolSize=2048
s.AsyncLoadingThreadEnabled=True
s.PriorityAsyncLoadingExtraTime=5.0
r.MaxAnisotropy=16
r.SceneColorFringeQuality=0
r.DepthOfFieldQuality=0

[ConsoleVariables]
p.NetClampErrorTotal=1
p.RigidBodyMaxSubsteps=1

Parameter Details & Technical Purpose

Parameter	Recommended Value	Technical Purpose
r.GTSyncType	1	Forces a tighter sync between the Game Thread and Rendering, critical for weapon-collision physics.
p.RigidBodyMaxSubsteps	1	Limits physics sub-stepping to ensure the simulation doesn’t “over-predict” movements in the 60Hz loop.
r.FinishCurrentFrame	0	Disables the engine’s attempt to wait for a full frame, effectively reducing input lag.
r.DepthOfFieldQuality	0	Removes background blurring, which is a known cause of frame-time spikes on certain stages.
r.Streaming.PoolSize	2048	Allocates a dedicated VRAM buffer for character and weapon meshes, preventing “pop-in” stutters.

Best Practices for 2026 SoulCalibur Physics Stability

To achieve a professional-grade setup for competitive play, follow these additional GameEngineer.net technical steps:

• The 1-Frame Lag Fix: By default, SoulCalibur VI adds an arbitrary 1-frame of delay to offline play to “simulate” online conditions. In 2026, competitive players use hex-editors or memory mods to remove this. If you want the fastest offline response, ensure r.GTSyncType=1 is active as it partially mitigates this at the engine level.
• Stage Selection Awareness: Stages like “Astral Chaos” or “Snow-capped Mountain” have heavy particle and physics interactive elements. If you experience slowdowns, lower the Effects Quality to Medium in the in-game menu; this directly reduces the number of physics-calculated particles.
• Scalability.ini Tweak: For maximum visual sharpness without a performance hit, add [PostProcessQuality@3] r.Tonemapper.Sharpen=1 to your Scalability.ini. This makes the characters “pop” against the background, aiding in visual reaction time.
• Full Screen vs. Windowed: Always use Fullscreen mode. Borderless Windowed in UE4 games can introduce an extra frame of latency via the Windows Desktop Window Manager ($DWM$), which can be the difference between a successful block and a Ring Out.
