Possible solution to Intel 12k e-core issues (Without using the BIOS).

[Cronofear]

If you have an Intel 12000k with e-cores, and specially if you aren't on Windows 11. Then you'll likely having stutter/slowmo issues with the game due to the game process using the e-cores. One solution is to disable the e-cores in the BIOS of your system.

But there may be another solution that doesn't require restarting the computer you can try and if it helps, confirm it so you can help the community:
- Open the game, then go to the desktop.
- Open the windows task manager (CTRL+SHIFT+ESC)
- In the task manager, go to the "details tab". If this is the first time you opened the task manager, click on "more details" so you can see the tabs.
- In the details tab, search for the game process ("WoLong.exe"), right click it and select "set affinity".
- You'll see that you have 4/8/16 CPUs to select, depending on what CPU you have. E-cores should be at most half of the highest CPU listed. So for example if you see "CPU 0, 1, 2, 3, 4, 5, 6, 7". Then the e-cores will be at most "CPU 4, 5, 6, 7". You can disable the e-cores here and make sure that the game is only using "CPU 0, 1, 2, 3".

You can make sure how many physical cores you have exactly by looking at your CPU specs. And as the general rule, the higher CPUs listed should be the E-Cores.

I *think* this helped a bit. I have an i7-10875H cpu (it's also a laptop) and I was having cpu usage issues (meanwhile the rtx 2060 didn't seem to be used at all). One thing is I had to of course exit/restart the game otherwise it was just chugging.

After disabling the virtual/logical cores the cpu seemed to reduce quite a bit and my gpu started being used more (though it was through Desktop Window Manager, but I assume because my laptop screen is integrated into my intel graphics and I can't change that, it's calculating thru my rtx and piping it to the intel screen. Don't know why it's going thru dwm tho lol). While testing some things I also noticed wo long kept switching between using my intel and rtx gpus so idk what the whole dwm thing was about. Still can't get it to use my gpu fully though, can't go past 70fps even on low settings but that just might be a me thing. Testing further it seems that the "usage" tracking for my gpu in the task manager isn't exactly accurate. When I turn up graphics, the card temp goes up but the "usage" is almost 0%.

I'm gonna continue doing some testing and hopefully disabling those cores helps fix some of my crashing issues. Thanks for the advice.

Thanks for the testing and reporting, OP.

For those who have hyper-threading enabled on their CPUs, don't forget that this doubles the number of performance cores that appear in the task manager affinity list. (So, a 12700 with 8 p-cores and 4 e-cores will appear to have 20 total cores running, for example.)

What a bloody mess this port is! I pray that TN & KT fix this soon, I really want to play this game.

I think people reported that the Resource Monitor gives a more accurate report of the hardware usage in this game.
You can open the Resource Monitor in Task Manager->Performance Tab->"Resource Monitor" in the bottom.
