How Well Modern Linux Games Scale To Multiple CPU Cores

Valve's older Portal game didn't make greater use of the system past three CPU cores.

Civilization VI was recently brought to Linux by Aspyr Media. With this game it wouldn't run on one CPU core, but beyond that it scaled quite poorly. There was large variations in the performance when at two to three cores but at four and above its performance was consistently flat.

The Talos Principle with its OpenGL renderer was the most odd result with next to no scaling but in some core configurations actually saw wild swings in the frame-rate.

Or with The Talos Principle's Vulkan renderer, the performance remained flat across the board.
