Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
O3DE
- Minimum hardware is a quad-core 2.5 GHz x86 CPU with SSE 4.1, 16 GB RAM and a DirectX 12 or Vulkan GPU with 2 GB VRAM and Shader Model 6.2
- Raytracing features require Shader Model 6.3
- Disk space required is 40 GB using the prebuilt installer and 100 GB or more when building from source
- Building the engine from source needs 2 GB of RAM per build thread on top of normal system requirements
- On Windows the editor requires Windows 10 version 20H2 or later plus Visual Studio 2019 16.11.x, 2022 17.3.x or 2026 18.0.x with the Game development with C++ workload
- The only primary Linux distribution for the editor is Ubuntu 22.04 LTS, and Ubuntu on 64-bit ARMv8 is experimental
- Linux builds need CMake 3.30.0 or later, which is newer than the 3.22 shipped by default with Ubuntu 22.04
- Wayland support is experimental, requires building from source, and is limited to the Game Launcher with no editor support until O3DE moves to Qt6
- Linux requires a long list of additional apt library packages to be installed before building
Quixel Mixer
- Discontinued as of February 19, 2026 with no future updates or support
- No built-in baker functionality unlike Substance 3D Painter
- Limited customization compared to industry-standard Substance Painter
- Megascans asset library now requires paid subscription instead of free access
