A noticeable drop in performance after installing REFramework in Monster Hunter Wilds is a common concern. In most cases, the framework itself is not the direct cause. Instead, performance issues are typically related to scripts, features, or system limitations introduced alongside it.
This guide explains the most common causes of FPS loss and how to resolve them.
Script Execution Overhead
REFramework acts as a lightweight hook, but any Lua scripts running through it consume system resources.
Each script placed in the autorun folder executes continuously during gameplay. When multiple scripts are active, their combined processing time can affect performance.
How to check:
Open the REFramework menu using the Insert key
Go to Script Runner
Review the execution time shown in milliseconds for each script
Scripts consistently using higher execution time can reduce overall performance. Disabling unnecessary or heavy scripts may improve frame rate immediately.
Frame Generation Conflicts
Certain versions of Monster Hunter Wilds may show conflicts between REFramework and GPU frame generation technologies.
Observed behavior:
Reduced GPU utilization when frame generation is enabled
Lower or unstable frame rate compared to expected performance
Recommended action:
Disable frame generation in the game settings and compare performance
Update to the latest REFramework build if available, as newer versions may resolve compatibility issues
Memory and VRAM Usage
REFramework increases overall memory usage and allows loading of additional assets such as high-resolution textures.
Potential issue:
Systems with limited VRAM may experience performance drops when memory usage exceeds capacity
Symptoms include:
Sudden FPS drops
Stuttering during movement or camera rotation
Recommended action:
Lower texture quality in game settings
Limit use of high-resolution texture mods
Use available optimization settings within REFramework to reduce load
Baseline Performance Testing
To determine whether performance issues are caused by REFramework or specific modifications, perform a clean test.
Steps:
Rename the dinput8.dll file to temporarily disable REFramework
Launch the game and record performance in a demanding scenario
Restore the file and remove all scripts from the autorun folder
Launch the game again and compare results
If performance matches the base game without scripts, the issue is likely caused by one or more mods rather than the framework itself.
General Optimization Recommendations
The following adjustments can help improve performance while using REFramework.
Keep the REFramework menu closed during gameplay to reduce overhead
Ensure graphics drivers are up to date
Enable or adjust available performance-related settings within the framework
Add mods gradually and test performance after each addition
Avoid running multiple heavy scripts simultaneously
Final Thought on Common Performance Issues
Reduced frame rate with frame generation enabled
Cause: Compatibility conflict
Solution: Disable feature or update REFramework
Stuttering during camera movement
Cause: Memory or asset loading limitations
Solution: Lower texture settings and reduce mod usage
Consistently low performance
Cause: High script execution load
Solution: Disable or optimize active scripts
Lag during menus or interface interactions
Cause: UI-related modifications
Solution: Remove or replace affected mods
