How Well Modern Linux Games Scale To Multiple CPU Cores

With all the discussions about AMD's Ryzen 7 processors that boast eight cores plus SMT, there has been much discussion in our forums and elsewhere the past few days about how many cores most modern Linux games actually utilize... That plus with looking at how well Ryzen's CPU cores scale, I have carried out some fresh Linux CPU core scaling benchmarks with an Intel Core i7 6800K Broadwell-E to see if most Linux games can end up using 4+ cores right now.
