Question Single Core Gaming - work load

[thrashers123]

Just want to know why when playing a single core game, in the cpu performance graphs, none of the graphs are running at full.

Windows is using thread migration/juggling,it is sending workloads around all available cores and threads to keep temps lower and prevent the first core from deteriorating faster then the rest.
You can use task manager to pin a process to a single core,in the detail tab by using right click affinity.

Just because an old game is only capable of utilizing one core does not mean that a single core would necessarily need to be maxed, as what GPU you have will certainly still come into play as well...(i.e, a hypothetical non-SMP capable Quake 2 game might still get 1000 fps with both a 7700K and a 9900K using a GTX1070, but, only 800 fps using a GT710; also, the 9900K's 500 MHz higher clock speed might generate less than max usage on a non-CPU intensive task, but, CPU higher usage when using the very best GPUs at lower res/details...)
