SpecSpoof: A fabric mod to modify the hardware string in the F3 menu!

SpecSpoof is a Fabric mod that allows you to modify the hardware string displayed in the F3 menu. With this mod, you can customize the hardware information shown in the F3 menu to your liking. Whether you want to show off your (fraud) high-end hardware or keep your specs private. Now depends on Roselib!

Compatibility

This mod should be highly compatible with other mods, but if you find any incompatibilities or bugs, just open up an issue in the GitHub repo. I'll probably try to implement a workaround.

Additional Infos:

ModMenu is recommended for easier config modification!

All options should be straightforward, so go nuts!

JSON Instructions (for legacy versions):

Quick Documentation JSON:

{
  "CPU": "your cpu name", //desired fake CPU name
  "GPU": ""your gpu name", // desired fake GPU name
  "FPS": 1000, // desired FPS to be faked as
  "disableFPSThreshold": 100 // The FPS Threshold for the fake fps to be deactivated, you see, to make it more believable, if your frames are dipping, the fps should actually reflect to that. imagine saying you have 1000 fps but your game runs like a slideshow, that just wouldn't work. (set to 999999 if you don't want this feature, set to 0 if you want to always fake your FPS)
  "GPUVendor": "the vendor", // This is what shows in the brackets right beside your resolution, you might want to change this to your desired GPU brand if you want to make it believable.
  "GPUDriver": "the driver" // This is the GPU driver string, which shows below the GPU string, you should also change this if you want to make your fake GPU believable.
}

The formatting is also your choice, you can make it actually believable or just put random nonsense on the string.

Examples:

{
  "CPU": "112x Intel(R) Xeon(R) w9-3495X",
  "GPU": "NVIDIA GeForce RTX 2080 SUPER/PCIe/SSE2",
  "FPS": 3400,
  "disableFPSThreshold": 100
  "GPUVendor": "NVIDIA Corporation",
  "GPUDriver": "3.2.0 NVIDIA 531.37"
}
{
  "CPU": "Rose Flowers",
  "GPU": "Pigeons",
  "FPS": 10,
  "disableFPSThreshold": 0
  "GPUVendor": "Eggs Inc",
  "GPUDriver": "1.2 months"
}

Small maintanance update + bugfixes



Vulkanmod support is completely dropped in this version, as vanilla already implements the vulkan renderer so i don't see the need of supporting it.

That's all, thank you for using SpecSpoof!

Small maintanance update + bugfixes

  • Updated to 26.1**
  • Fixed a bug where the text on ModMenu's options screen to be missing**
  • Made FPS spoofer a bit more beleivable for vanilla**


  • [Vulkanmod](https://modrinth.com/mod/vulkanmod) support is dropped again for this release temporarily,** as the mod is not yet updated as of writing this. it may come back as it is just a 1 line change assuming vulkanmod didn't change anything.

I also noticed that [Sodium Extra](https://modrinth.com/mod/sodium-extra) has removed their FPS counter (?), The code to alter it is still there... just in case...

That's all, thank you for using SpecSpoof!

Huge Update for Mod compatibility & Performance!

thanks to "modCompileOnly", it allowed a way for me to patch certain things from external mods easily


This is the kind of update i don't regularly do because they take a bunch of energy from me, but i just felt like it for this one so that SpecSpoof can somewhat have a better quality as a Minecraft mod. Especially after all these years of me diving into Minecraft Modding

Thanks for using SpecSpoof!

Small maintanence update

  • Support 1.21.6

### IMPORTANT NOTE:

  • Vulkanmod support is dropped**, this might be permanent im not sure. i simply do not have the required energy to maintain a mod with external dependencies.

Vulkanmod, in particular, added so much bloat to SpecSpoof’s codebase that I had to create my own abstraction layer in RoseBush just to handle reflection. At that point, things got out of hand.

If I do end up dropping Vulkanmod permanently, feel free to fork the project and maintain support yourself!

Critical fix update!

  • Fixed an issue where SpecSpoof would spam the console**, previously it would spam "Options fetched successfully" per frame, which is incredibly exhausting.
  • Removed STDOUT logging in some areas in place for LoggerFactory**, So the prints from SpecSpoof is way more concise.

Sorry this took to long to catch. have a nice day!

Massive update internally.

  • Dropped versions below 1.21**, development will only move forward.
  • Config system fully refactored**, now using [Roselib](https://modrinth.com/mod/rose-bush) as backend _(this generally means less config related errors if you experience that a lot in previous versions)_
  • Config hot reload upon saving changes from [ModMenu](https://modrinth.com/mod/modmenu)** _(no more restarting game when you have ModMenu)_
  • Removed "Open JSON File" option in the [ModMenu](https://modrinth.com/mod/modmenu) GUI
  • Added a button beside each fields to reset the field's value to default** _(The R button)_

That's it, thanks for using the mod!.
