What modern games or s/w benefits heavily on single core performance?
All the games and s/w I am running uses multiple cores, as I can clearly see on my secondary monitor, were I have
Core Temp gadget and
FPS Monitor (FPS counter on game screen) widgets to keep an eye on my CPU and my GPU (Asus AMD RX 6900 XT).
My primary monitor is a 27" 2560x1440 @165 Hz. I have limit it to 120 Hz so that I can try to maximize quality and as quiet as possible (low temp) gaming.
I would love to have an even heftier 16 core CPU, such as Ryzen 9 7950X, but the price tag for a new mobo, CPU, DDR 5 memory etc would make it hard on this side of the new year...
For example Assassins Creed Odyssey can use up to 12 cores and same goes for many other games, some can use all avaible cores.
This shows right now how Ghost Recon Breakpoint uses 8 CPU cores as well GPU load, GPU memory load and temp etc. on ultra settings - and very quiet gaming experience.
