Mewgenics Low FPS Fix Guide: How To Fix Stutter, Lag, And Slowdowns
If Mewgenics is running at low FPS, stuttering during combat, or slowing down when you have too many cats, the issue is usually Windows configuration, drivers, or power settings. The game runs on a custom C++ engine, not Unity or Unreal, which makes it efficient but also sensitive to missing libraries and refresh rate conflicts.
Before assuming your PC cannot handle it, go through the fixes below. Most performance issues are environmental, not hardware failure.
What Causes Low FPS In Mewgenics
Mewgenics is CPU heavy. The simulation handles genetics, AI turns, status effects, and terrain interactions at once.
Common causes of low FPS:
Outdated GPU drivers
Missing Visual C++ libraries
Windows power saving mode
Fullscreen optimization conflicts
Background programs competing for CPU
Fixing these often restores normal performance immediately.
Method 1: Verify System Requirements
Minimum requirements:
Windows 10 64 bit
Intel Core i3 4130 or equivalent
4 GB RAM
GeForce GTX 650
DirectX 11
Recommended:
Windows 10 or 11 64 bit
Intel Core i5 8400 or better
8 GB RAM
GeForce GTX 1050 Ti
The graphics are simple, but the simulation logic leans on CPU performance.
Method 2: Update Visual C++ Redistributables
Mewgenics runs on a custom C++ engine written by Tyler Glaiel. If your Visual C++ libraries are missing or outdated, performance and startup behavior can break.
Install:
Microsoft Visual C++ Redistributable 2015 to 2022
Both x86 and x64 versions
If you recently reinstalled Windows, this step is critical.
Method 3: Update GPU Drivers
Even 2D games rely on proper OpenGL and DirectX handling.
Update Nvidia or AMD drivers to latest version
Restart your PC after installing
Driver conflicts can cause stutter, screen flicker, or unstable frame pacing.
Method 4: Disable Fullscreen Optimizations
Windows fullscreen optimization can interfere with performance.
To disable:
Right click Mewgenics.exe
Click Properties
Go to Compatibility
Check Disable fullscreen optimizations
Click Apply
Restart the game after changing this.
Method 5: Fix Refresh Rate Conflicts
If the game feels choppy even with high FPS, it may be a refresh rate issue.
Try:
Forcing windowed mode using Steam launch option
-windowedAdjust resolution and refresh rate in game settings
Some monitors default to unusual refresh rates that conflict with presentation settings.
Method 6: Set High Priority In Task Manager
If simulation lags when many cats are active:
Open Task Manager
Go to Details
Right click Mewgenics.exe
Set Priority to High
Do not set to Realtime. High is sufficient.
Method 7: Plug In Laptops And Disable Power Saving
On laptops:
Plug into wall power
Set Windows Power Plan to High Performance
Battery mode throttles CPU speed heavily, which affects simulation performance.
Method 8: Reduce Visual Effects
If available in settings:
Lower particle effects
Reduce visual noise or grain
Disable unnecessary visual filters
This reduces GPU strain and smooths frame pacing.
Common Performance Errors
Error 0xc0000005
Often antivirus interference. Add Mewgenics folder to exclusions.
Missing MSVCP140.dll or VCRUNTIME140.dll
Install Visual C++ Redistributables.
Fatal Error loading save
Rename persistentgamedata file in Documents under My Games to force regeneration.
Final Blurb
Low FPS in Mewgenics is usually caused by missing C++ libraries, driver conflicts, or Windows power settings rather than raw hardware weakness. Because the game runs on a custom C++ engine, it depends heavily on a clean Windows environment. Update drivers, install Visual C++ redistributables, disable fullscreen optimizations, and check power settings before assuming your PC cannot handle the simulation.
FAQ
Why is Mewgenics CPU heavy
The simulation handles genetics, AI behavior, and combat logic simultaneously.
Does reinstalling the game fix low FPS
Usually no. Driver and C++ fixes are more effective.
Is this a Unity optimization problem
No. The game runs on a custom C++ engine.
Why does my laptop run it poorly on battery
Windows reduces CPU performance on battery power.
