Valor Mortis
Low-end PC guide: FPS boost, lag and stutter fix

Valor Mortis config file

- Put it in
%LOCALAPPDATA%\ValorMortis\ Saved\ Config\ Windows - Engine
- Unreal Engine 5
Valor Mortis runs on Unreal Engine 5.7, and its minimum graphics card is an AMD Radeon RX 5600 XT or an Nvidia GeForce GTX 1660 Ti. This guide gives you a free config file that turns down the heavy lighting, shadow and detail settings, the in-game settings to change first, and fixes for stutter on a weak PC.
Can you run Valor Mortis on a low end PC?
- OS: Windows 10
- CPU: AMD Ryzen 5 3600 or Intel Core i5-10600K
- GPU: AMD Radeon RX 5600 XT or Nvidia GeForce GTX 1660 Ti
- RAM: 16 GB
- DirectX: 12
- Storage: 60 GB
If your PC is at or above these specs, the config and the settings below should help. If it is below them, expect low frame rates and stutter even with this config. The config reduces graphics work, but it can’t replace missing hardware.
Best Valor Mortis settings for low end PCs
Start with the lowest graphics options the game offers, then change these:
- Upscaler: Pick TSR or XeSS 2, since both work on any GPU. DLSS 4.5 needs an Nvidia RTX card, and FSR 4.1 needs a recent AMD card.
- Ray tracing: Turn it off. Ray tracing is one of the heaviest settings on older graphics cards.
- Frame rate cap: Set it to 60. If your PC can’t hold 60 frames per second, set it to 30. A steady 30 is smoother than a 60 that drops in and out.
- V-Sync: Turn it off. It can hold your frame rate to your monitor’s refresh rate and add input lag.
- Window mode: Pick borderless windowed if you switch between apps often.
Valor Mortis Engine.ini location and install
- Download the zip with the button above. Unzip it and find the
Engine.inifile. - Close Valor Mortis completely, including any launcher that is still running.
- Press Windows + R, paste
%LOCALAPPDATA%\ValorMortis\Saved\Config\Windowsand press Enter. If the folder doesn’t exist, start Valor Mortis once, close it and try again. - If the folder already has an
Engine.ini, rename it toEngine.ini.bak. This is your backup. - Copy the new
Engine.iniinto the folder. - Start the game.
What the config changes
The file changes only the graphics settings listed here. It doesn’t touch network settings, so don’t expect it to change online lag.
Post-processing
- Motion blur is off.
- Depth of field is off.
- Color fringing at the edges of the screen is off.
- Lens flares are off.
- Light shafts are off.
- Film grain is off.
- Sharpening is set to 0.6.
Lighting and reflections
- Ambient occlusion, screen space reflections, subsurface scattering, contact shadows and capsule shadows are off.
- Volumetric fog uses a coarser grid.
Shadows
- Shadow quality is set to 2.
- Shadow resolution is capped at 1024.
- Shadows reach a shorter distance.
- Small objects cast shadows less often.
Draw distance and foliage
- View distance is set to 80 percent of the default.
- Detail mode is set to 1.
- Anisotropic filtering is set to 4.
- Grass and foliage density is set to 60 percent.
Lumen, Nanite and virtual shadow maps
- Lumen reflections are off.
- Lumen mesh distance field tracing is off.
- Nanite detail is set lower.
- Virtual shadow maps use a lower resolution for directional and local lights.
The streaming settings turn on async loading and turn off forced and incremental garbage collection, for smoother loading and fewer hitches when you move between areas.
How to fix Valor Mortis stuttering and FPS drops
Valor Mortis is an Unreal Engine 5 game, so the first launch compiles shaders. Let that finish, and expect hitches for the first few minutes.
If you can, install the game on an SSD. It needs 60 GB of storage.
Then work through the basics on Windows:
- Close background apps, such as browsers and overlays from launchers.
- Update your GPU driver from the official site: Nvidia, AMD or Intel.
- On a laptop, plug in the power cable and set the power mode to best performance.
Undo the changes
Delete Engine.ini from the folder. If you made a backup, rename Engine.ini.bak back to Engine.ini instead. The game rebuilds its defaults.
Valor Mortis FAQ
Where is the Valor Mortis Engine.ini file?
Valor Mortis keeps it in %LOCALAPPDATA%\ValorMortis\Saved\Config\Windows. Press Windows + R, paste the path and press Enter. If the folder isn't there yet, start the game once, close it and check again.
Can Valor Mortis run on a low end PC?
Valor Mortis needs at least an AMD Radeon RX 5600 XT or an Nvidia GeForce GTX 1660 Ti, with 16 GB of RAM. A PC below that may run it poorly even with the Engine.ini file, because the file lowers the load on your GPU but can't replace missing hardware.
Which upscaler should I use on an older GPU in Valor Mortis?
Pick TSR or XeSS 2, since both work on any GPU. Valor Mortis also offers DLSS 4.5 and FSR 4.1, but DLSS needs an Nvidia RTX card and FSR 4.1 needs a recent AMD card, so older GPUs should skip them.
How do I fix Valor Mortis stuttering and FPS drops?
Let the first launch finish, since Unreal Engine 5 compiles shaders and causes hitches for the first few minutes. Install the game on an SSD if you can. Close background apps, update your GPU driver and use the best performance power mode on a laptop.
What frame rate cap should I use for Valor Mortis?
Set the frame rate cap to 60. If your PC can't hold 60 frames per second, set it to 30 instead. Turn V-Sync off, and pick borderless windowed mode if you switch between apps often.
