After a successful exploration of unity earlier, I though I would test-drive Unreal Engine 4 to see what that is all about. Here are some random observations I made:

  • For linux, the engine and editor have to be built from source. Which is fine, but it does take an hour, and 60Gbyte of disk space.
  • First time starting the editor takes a very long time, and comes with scary warnings to boot.
  • Once you actually try to launch a sample, everything is very slow. Thousands of shaders need to be compiled.
  • Be careful with that quality slider. If you change it from "High" to "Medium" be prepared for another lengthy shader recompilation step.
  • The vulkan renderer would crash at startup with an out-of-memory error. But switching to OpenGL renderer, helped.
  • Out of box performance when launching the "Advanced Vehicle" template was dreadful. I estimate the FPS well below 10 for that. I need to figure out if this is a GPU or CPU bottleneck. Although performance is a lot better if I first quit the editor, and then start the demo application by itself.
