Yesterday afternoon, Epic announced that a hotfix for Unreal Engine 4.1 is available, patching the engine to 4.1.1.

This hotfix addresses crashing and unnecessary shader compilation in Unreal Engine 4.1.


– Fixed shader material instances not being saved to DDC, causing many shaders to be rebuilt when loading the editor.
– Fixed crash on iOS/Android reading blueprint assets with certain unaligned opcodes.
– Fixed handling of volume buttons on Android.
– Fixed sporadic crash caused by race condition in the XboxOne texture compressor.
– Fixed engine compiling more shaders than necessary in the material editor.
– Fixed severe performance regression for some GPU combos on Windows, where the engine would fall back to the software renderer.
– Fixed crash when pressing the news feed refresh button multiple times.
– Updated .gitignore to include SDL2
– Addressed an analytics error
