Dead Cells - Ultrawide Fix

MY MAN

Wow! And they said it was impossible because pixel perfect game and yada, yada, yada

Thanks!!

Hi, thanks for the patch! however, I cant seem to get it working with extracting the files into the game file. Has this been patched?

Don't know how much different the files are on the Xbox app but it would be nice to see this updated for that.

Can you please update this for the new castlevania dlc? its very glitchy

Would also really appreciate an update for the Castlevania DLC

Are there any plans to update this for the current version?

Adding my vote: Would greatly appreciate it if you updated for the Castlevania DLC!

pls 5120x1440

A shame this hasn't been updated in years

A shame this mod was abandoned 2 years ago, it doesn't work now

2k24 newest steam version, windows - still works

ITS WORKING Y'ALL! 🙂

As of 5/23/2025, this ultrawide fix works by editing one of the shader files used by Dead Cells. After extracting the mod (https://community.pcgamingwiki.com/files/file/2504-dead-cells-ultrawide-fix/), in each folder (only need 1 of the 4), you should have three files and one folder:

• d3d11.dll
• d3dx.ini
• nvapi64.dll
• ShaderFixes (folder)

Inside the ShaderFixes folder, there will be a file named:

• cc2a82ee0453aea8-vs_replace.txt

Open that file in a text editor and look for the following lines:

• if (o0.x > X1_OFFSET) { o0.x += X2_OFFSET; }
  else if (o0.x < -X1_OFFSET) { o0.x -= X2_OFFSET; }

Replace X1_OFFSET and X2_OFFSET (these are actual numbers in the file) with the values that match your resolution from the table below. ... anything works, this should be enough to determine your preferred ratio, just do the math if you don't see yours. 😉

Resolution === Aspect Ratio === X1_OFFSET === X2_OFFSET
2560x1080  === 21:9         === 0.799     === 0.22
3440x1440  === 21:9         === 0.789     === 0.21
3840x1600  === 21:9         === 0.747     === 0.25
3840x1080  === 32:9         === 0.494     === 0.52
5120x1440  === 32:9         === 0.494     === 0.52
3840x1200  === 32:10        === 0.622     === 0.38
5120x2160  === 64:27        === 0.494     === 0.52
5760x1080  === 48:9         === 0.329     === 0.68
7680x1440  === 48:9         === 0.329     === 0.68
6880x2880  === 43:18        === 0.399     === 0.60

These values define where the game begins stretching the scene to fill a wider aspect ratio (X1), and how far it pulls those edges outward (X2). Picking the right pair ensures you get a wider field of view without breaking the UI.

***Important***: Be sure to run the game in Maximized Windowed Mode, not Fullscreen or Borderless, to avoid HUD stretching. This setting preserves UI integrity while allowing proper ultrawide rendering.

After you edit the offset values, save. Then drag the follow files/folders into C:\Program Files (x86)\Steam\steamapps\common\Dead Cells and enjoy!

• d3d11.dll
• d3dx.ini
• nvapi64.dll
• ShaderFixes (folder)
  • cc2a82ee0453aea8-vs_replace.txt
