PFG Add-On: Multi Frame Generation for Minecraft
Minecraft has always been a game where performance matters, but with the rise of shader packs, high-resolution resource packs, and sprawling builds, even powerful PCs can struggle to hold a smooth frame rate. The PFG add-on tackles this problem head-on by introducing Multi Frame Generation to Minecraft, using motion vectors in a way that mirrors modern upscaling and frame generation technologies like DLSS and FSR. If you have ever watched your FPS counter dip below comfortable levels while running a beautiful shader setup, this mod is worth a closer look.
What Does PFG Do?
PFG is a rendering-focused add-on that generates additional frames between the ones your GPU already renders. It works by extrapolating data from the depth buffer, the color buffer, and the G-buffers, with motion vectors doing the heavy lifting. The result is an interpolated image that gets displayed on screen, effectively multiplying your perceived frame rate without asking your hardware to render every single frame from scratch.
The early numbers reported by the developer are impressive. Initial estimates sat around 100 FPS in test scenarios, with 2X mode pushing that to roughly 170 FPS, 4X mode reaching around 380 FPS, and 6X mode climbing toward 500 FPS. These figures depend heavily on your hardware, your shader configuration, and your base frame rate, but they illustrate the potential of frame generation when it is applied to a blocky sandbox world.
Frame Generation and Upscaling Explained
Starting with version 2.0, PFG also adds FSR1 upscaling alongside frame generation. That means you get two performance tools in one package: upscaling to reduce the rendering load, and frame generation to smooth out motion. One important note for shader users is that you should reload your shaders every time you change the FSR1 resolution, otherwise the image may not update correctly.
Another practical detail: the standard F3 debug screen does not count generated frames, so it will not reflect the true frame rate you are seeing. For accurate readings, it is recommended to download a compatible FPS counter that can measure the output properly.
Compatibility and Supported Versions
PFG is designed to be paired with performance mods like Oculus or Embeddium, although this pairing is entirely optional. The mod is also built to be fully compatible with shader packages, which makes it a natural fit for players who refuse to give up their lighting effects. In terms of loaders, PFG for Minecraft is aimed at the Fabric ecosystem, and it targets modern Minecraft releases where Fabric rendering mods are actively maintained. As always, check that your loader version, your performance mods, and PFG itself are all aligned before you start tweaking settings.
If you would rather skip manual file management, the foxygame.net launcher can handle the whole process for you, offering one-click installation of PFG directly into a compatible profile so you never have to touch the mods folder.
How to Install PFG
Getting the add-on running is straightforward once your environment is prepared. Follow these steps:
- Install a compatible Fabric loader for your Minecraft version and run the game once to generate the necessary folders.
- Place Fabric API and any optional performance mods such as Oculus or Embeddium into your mods folder.
- Download PFG and drop the jar file into the same mods directory.
- Launch Minecraft, then press F6 in-game to open the frame generation menu.
- Choose your multiplier, adjust FSR1 settings if desired, and reload your shaders after any resolution change.
Once configured, the difference in motion smoothness becomes obvious, particularly in busy areas like villages, redstone contraptions, or heavily decorated bases.
Using the Frame Generation Menu
The F6 menu is the control center for everything PFG offers. From there you can toggle frame generation, select your multiplier, and fine-tune the upscaling component. Because the settings interact with your shader pipeline, it pays to test each change individually rather than adjusting everything at once. A quick walk through a demanding area will tell you more than any benchmark number.
Final Thoughts
PFG brings a genuinely modern rendering technique to a game that many players assumed would never see it. Multi Frame Generation, FSR1 upscaling, and shader compatibility combine into a package that can transform how Minecraft feels on mid-range and high-end systems alike. The developer has also been refreshingly transparent about using AI assistance for parts of the GUI and a few functions, which is a detail worth appreciating in today's modding landscape. If smooth frame rates matter to you, PFG for Minecraft deserves a spot in your loadout.
