FrameGen

Pick a target FPS. FrameGen generates the frames your GPU can’t render in time.

No RTX, no DLSS, no Vulkan renderer — plain OpenGL 3.2, the same as Minecraft itself.

How it works

Every real frame is saved together with its depth. When the next frame would be late, FrameGen warps the saved one to your current camera instead of rendering the world again. Looking around stays smooth and responsive.

Features

• Target FPS from 30 to 500, or your monitor’s refresh rate. No multiplier to tune — it adjusts itself.
• Real frames come first. Generation only fills the gap, and never pushes real frames below 30 FPS (configurable), so the world keeps moving.
• Live frame-time graph: real frames green, generated cyan, spikes red, plus 1% low.
• Iris and Oculus shader packs (experimental).
• HUD caching for heavy modded HUDs.
• F9 on/off, F10 settings.

Good to know

• Frame generation multiplies performance, it doesn’t create it. Aim for 40–60 real FPS first.
• Minecraft has no motion vectors, so mobs, particles and water move at the real frame rate.
• Best with VSync off.

Requirements

• Client-side only
• Any GPU that runs Minecraft: GeForce 400+, Radeon HD 5000+, Intel HD 2500+, Apple M1+
