Bad performance on Intel Comet Lake i5 CPU (10th Gen)

Hello,
I'm playing WoW on an Intel Core i5-10600 (6x4,8 GHz) paired with an Radeon Pro 5300 (about 30-40% usage only) and 16GB RAM. My CPU seems to be using only 1 core at 100% and the others sitting at 1-5%. The frustrating thing is that on my older PC's WoW ran just fine with constant 144 FPS (escpecially with 4 core/ 4 thread CPUS) and with the powerful new CPU WoW is barely running with 60 FPS and drops below 30 FPS in some situations. Even on the current retail patch (with far higher graphics settings) I get constant 144 FPS because all cores are used in parallel. I know for sure that WoW 3.3.5a is able to use more than 1 core.

Things I tried without success:
- SET processAffinityMask "X" (not working at all, with different numbers for X
- Set CPU affinity in Taskmanager (says that WoW is using multiple cores but situation stays the same)
- Disbale cores via msconfig to get a 4 Core CPU (disables Hyperthreading)
- Reinstall WoW / different version than warmane
- Reinstall drivers
- Disbaled power savings / windows features like DVR and so on
- Disabled all addons

Is there anyone who's using a Intel 10th gen processor with good CPU utilization?

Wotlk can use more cores but it's only able to use a single core efficiently. UI and addon functionality is almost entirely single-threaded and some of it runs before every frame. Only when that's done, rendering the next frame can start and with DirectX 9, that's also mostly single-threaded process.

Still the performance should not be worse on a newer CPU. Maybe you got higher resolution monitor too? Resolution can still affect performance when the rest of graphics settings are the same. You could also try lowering multisampling.

The monitor and therefore resolution is the same (1440p @ 144 Hz). Only GPU load is affected when I change multisampling. For me it's clearly a problem with core affinity but I couldn't find a way to solve it yet.

Out of curiosity what was the old CPU you had?

I switched from an i5-7500 (4 cores / 4 threads). In the past I played on an old i5-3570k which reached far better performance than the 6 cores / 12 threads i5-10600 (with a lot higher single thread performance) in WoW 3.3.5a aswell.

I you think it's cpu matter > go to intel website, they have some cpu checker. Take the one for you cpu.
You should check if your uefi setting are correct, an update.

futhermore if you use the last gen of motherboard with z490, good luck. These motherboards sucks they have so many problems, intel said about it do no use it or be careful.

p.s: intel cpu 9 -10 gen suck (they are some execptions) but for i5 most of them suck because they are not like before a branch of cpu by itself. They are i7 with block perf
