Render freeze fix for forge 1.20.1
by Spiinosauro
Render freeze fix for forge 1.20.1 addresses the render thread freezes that Intel graphics devices hit on earlier Minecraft builds.
What it does
When the render thread stalls on Intel devices, the game can freeze until the player relaunches it. This mod targets that render thread bug so the window keeps responding and the world keeps updating around the player, with only a brief stutter instead of a full stop. Its author reports a clear improvement on their own machine, but the mod is aimed at this one bug and does not change general performance. Installation covers the server and each player's game. Files are published for Forge 1.20.1, with 2.3.0 as the latest beta from 2025-08-14, under All rights reserved.

What the author says
This mod fixes a render thread bug in minecraft pre 1.21.8 that on intel devices would freeze the game window without actually freezing the game (like you see one frame but you can hear the world around you working normally). With it instaled, instead of freezing the game for eternity it just lags for half a second…
