What is the most demanding game to run in Single Core mode?

[TomSea64]

I have my i5-8600k running at 5.0ghz and my goal has been to have Dolphin run as accurately as possible. I have read that single core mode is more accurate than dual code and the likelihood of their being issues is much lower. Also i believe i read something about the GPU driver can have an effect in dual core mode while it won't effect it in single core mode. Lately not only with Dolphin but with every emulator i have used i want it to be as accurate as possible. Games like Mario sunshine,Paper Mario TTYD,Double Dash,F-zero GX, And brawl run fine. Also i have another question. I have a Free sync Monitor and i want to make sure my frame pacing is consistent as possible, Should i disable Skip presenting duplicate frames and leave V sync off? I already leave V sync off because of free sync but i want to make sure that my frame pacing is as consistent as possible

Anything that hammers the CPU thread and GPU thread at the same time will be very challenging in single core mode. So I'd recommend Metroid Prime 3 and Last Story as good examples of where dual core still does a lot.

Nooot really no. The problem with dual core mode is all from the fact that we're taking an emulated single core CPU and splitting it between two host CPUs. Sure we are dividing it between CPU and GPU related tasks, which is moooostly ok, but we're still splitting a single core into two cores, and problems will always come from that. However, once we've passed everything to the video driver this distinction doesn't matter.
