95% CPU Usage
So why is this game pushing my processor almost to the max? I'm reading 95% usage with temperatures at 81 degrees while playing the game. Insane.

I'm on Ryzen 5 3600 stock, cooled by Noctua NH-D15s with RTX 2070 in a well-ventilated case. Definitely not a hardware or cooling problem.

Are you running anything else in the background? Streaming, antivirus, download programs, browsers, overclockers?

If yes to any of those, that could be your problem. You might also want to check your settings and see if its are CPU or GPU controlled in the graphics options and change it, that could help things.

MK is sucks

Changing these options didn't help. I'm also not running anything substantial or unnecessary in the background while playing.
81 degrees means something is wrong with your cooling system. Personally, I keep my CPU always below 70 degrees with Prime95 stress test for 12 hours straight, reaching 70 degrees or more, then I improve/change my cooling system, or change/adapt my overclocking. Maybe you can have read about temperature issues with Ryzen 5 3600 https://community.amd.com/thread/241707

Back to topic, MK11 seems to have strange behaviour with some CPUs, I do not have this issue for example.

I do suspect now that there's something wrong with temps. Maybe I didn't install the cooler properly and that the thermal paste isn't evenly spread or something. But this is beside the issue, which is abnormal CPU usage going all the way up to 95%. No game right now should be capable of pushing this processor that far.

aslong as its not throttling your cpu back, 81 degrees is fine, your running an air cooler thats like 5 years old.

the 3600s have always ran hot under load.
they natually run silly voltages, people have fixed high temps by offsetting the voltages slightly and it drops by about 10 degrees.

When the game starts it does some kind of big scans. Just wait till it is done and it wont eat up your cpus anymore. I have a ton of cores/threads, and it occupies exactly 16 threads 100% until the scans are done. Which could be a minute.

Check your bios settings. Ryzen 3000 series tend to put too much voltage than what the cpu needs. Mk 11 should not push your cpu that hard even the temps should much lower.

Core voltage is 1.45v at stock. That seems excessive. I did consider undervolting but if I remember correctly AMD said that's normal for Ryzen 3000 processors and advised against reducing voltages since that would compromise performance.

Temps are better now. It turned out I had been underestimating things when setting up the fan curve.

I do want to find out exactly when the game does overload the CPU. I will be fine with it the this 95% load is not constant.

cpu vcore is too high. there was jayz 2 cents guid that he posted about those values. drop your cpu vcore to around 1.25v or max 1.28v

It appears that this abnormal CPU usage happens only when the game is in the loading screen. This is not good for the processor in the long-term given how often the player has to go through this loading process. It's like running a CPU stress test every time the game loads something. Ridiculous how they haven't yet fixed this poor optimization issue.

Dropping vcore will degrade performance. I'm reading 1.35v to 1.46v when gaming.

You need to learn a thing or two about computers. bud. 1.46v is very high for 4.2ghz. The secondly high cpu usage does not dot degrade cpu lifespan. They are meant to run at max load 24/7

AMD is always pretty generous with their voltage.

The CPU spikes are anti-cheats on top of the already-present DRM.

It seems like the complaints about this always coincide with older Intel chips or AMD chips. The anti-cheat crap is probably tailored for more recent Intel silicon. As that aforementioned anti-cheat/DRM ♥♥♥♥ is not being made by either or QLOC or NRS, there's probably a different process/standards for what constitutes good hardware support practices.

I just hope one day they take the ♥♥♥♥ off so people can have back the game before that May patch that ♥♥♥♥♥♥ it up.

And you need to learn a thing or two about Ryzen 3000 processors. Undervolting this thing will compromise performance. Either AMD likes it that way or this is an early adopter's problem whose only solution is more time for the BIOS/drivers to mature. Besides, high temps caused by overloading the CPU is what might degrade the processor overtime. I mean there are people talking about their CPUs getting literally burned by this game.

Update.

I've just dropped the vcore from 1.45v to 1.25v. As expected, performance has taken a hit. Cinebench score is reduced by roughly 300. It seems like the Ryzen 3600 is indeed meant to run on 1.45v by default for some reason. On the other hand, temps have improved significantly. Max temp at 100% load has dropped 21 degrees. Strangely, MK 11 appears to have stopped putting a 95% load on the processor. Now it doesn't push beyond 60%.

No idea what is going on here.
