Building Unreal Engine for Ubuntu Mate 20.04

My Specs:

  • OS: Ubuntu MATE 20.04 (LTS)

  • GPU: AMD Radeon HD 6670 / 7670 (Turks XT) - OpenGL 4.4 only (No Vulkan).

  • CPU: Intel Core i3-4150 @ 3.50GHz (2 Cores, 4 Threads)

  • RAM: 10GB

Questions:

  1. Which version is the “lightest” and most stable for a non-Vulkan Linux setup? Is 4.27 the safest bet, or should I go older?

  2. Will the WebGL build tools work reliably on a machine of this age.

  3. Are there specific Editor settings I should toggle to reduce the load on an older OpenGL card?

Thank you!
