Techy here, and i worry on the latest version for the safety of peoples computers when i see extreme abnormalities in the way the game utilizes the CPU to such an egregious extent.

I hope that sooner rather than later, the game can become safer for people to play, as it currently burns peoples CPU's like a constant stress test would. I urge the Fun Pimps, to please reduce the weight put on CPU usage. You need to optimize CPU usage, before the latest version can be safe enough for release.

Below i will compare CPU temperature performance compared to other games, to show you the extent of the effect you are putting on peoples hardware.

Im running a H80i V2 Liquid cooler on high performance settings. (faster fan rates, faster pump)

Processor is a Ryzen 7 1800x (2 months old)

Graphics Card is a GTX 1060 6gb (palit dual fan)

Cpu Temperatures: (United Kingdom in Winter, ambient temp = 5'c)

GTA5 1080p Ultra settings: Max temp reached 38'c

Supreme Commander 5,000 Unit stress test: Max temp reached 43'c

Warframe max settings: Max temp reached 35'c

Witcher 3 high settings: Max temp reached 44c

Black Desert Online, max settings: Max temp reached 45'c

>7 Days to Die, lowest settings: Max temp reached 72'c constantly remaining in the high 60's. (75'c is the default emergency shutdown temperature for this CPU)

>7 Days to Die, lowest settings, CPU hugely underclocked by 50%: Max temp reached: 46'c with suprisingly no effect on framerate.

It is interesting to me that with a 50% downclock, on the latest processors...reveals that performance doesnt take a hit, and temperatures cool down to safe levels. This only confirms to me that there are large glaring problems with the way 7 Days to Die currently handles the processor. Drastic optimization needed. If that 50% of my CPU isnt needed, why does 7 Days to Die insist on constantly burning it at full throttle?

Please address this as a major issue. Whilst we do want to see the new build ready for release, we also want it to be safe to play on our hardware.

 
This post doesn't really make sense.

I expected to look at your data and see temperatures in the high 90s but instead your highest temperature listed was 72c. These operating temperatures are COMPLETELY safe and would remain so up into the high 80's and even low 90s if only for short periods of time.

Not to be rude but this leads me to believe that you're confused or misinformed.

The Ryzen 7 1800x has a max safe running temperature of 95c.

Some sources claim 95c is the max running temperature period before incurring thermal shutdown, but innumerable user reports record stress testing at 95c and 96c with no thermal shutdown. One (unconfirmed) theory for this is that the chips were supposedly designed to intentionally give a temperature +20 above the actual temperature to motherboards to trick them into a more aggressive fan curve. This is just hearsay though, and I do not claim it to be true or false.

1. I don't know of a modern CPU in existence that throttles below 90c, and I've never seen a modern CPU thermal shutdown below 95c.

2. Stress tests regularly run CPUs well into the low 90s, without inducing thermal throttle or thermal shutdown. This temperature would only be concerning if a typical gaming load reaches these temperatures consistently. Short spikes to it are fine, this is generally explained by a sudden increase in utilization, and therefore voltage, which results in a short spike in temperature while the fans catch up in RPM in response.

3. Most people not running water cooling run under load anywhere between the low 60's to high 80's depending on the chassis size and form factor, chosen cooling configuration and software based solutions (RPM to temperature curves), CPU model, overclocking, state of cleanliness within the build, and a myriad of other such factors. These operating temperatures are almost always COMPLETELY safe, with some but very few exceptions.

In my entire life experience with building computers and gaming, I have NEVER had a CPU go through a thermal shutdown at less than 99c.

For some anecdotal evidence let me tell you about my CPU.

I have an i7 8700k. It's default turboboost is 4.8GHz at an obnoxious 1.42v, which means the chip will run really hot when turboboosting by default. Couple that with a manufacturing defect in this line of chips where there is a tiny air gap between the CPU die and the IHS or Integrated Heat Spreader (which incurs serious thermal ramifications) and you can safely say it's one of the hottest out-of-box chips around. This chip line runs so hot many reputable sources actually suggest you choose a comparable alternative that lacks this issue unless you're willing to A.) underclock it or B.) delid (a serious and expensive decision) and apply Conductonaut to the die to combat the issue!

My ambient temps are consistently around 24c (75f, we have central air). My 8700k is running downclocked to 4.6GHz @1.2v with an Enermax ETS T40 air cooler, with one of the fans (the pull fan) removed because it's broken. Under the absolute heaviest of CPU gaming loads it runs consistently between 80c - 89c across 6 - 8 hour sessions with no performance throttling. It rarely ever reaches the higher side of that distribution, when it does it's due to the sudden escalation of utilization, during the second or so it takes the fans to catch up in RPM after recognizing the temperature spike. So what's my point?.

Despite all of the factors in place to make my CPU a prime choice to potentially suffer from this issue, 7 Days to Die struggles to push it into the high 70s.

Also, temperatures and utilization have not changed in any meaningful way since 16.4. I am quite dilligent in monitoring temperatures while gaming. My secondary screen is has the sole purpose of showing diagnostics while gaming.

Therefore, I posit that your assertions are incorrect. Perhaps you are having issues but they are on your end and not the fault of the game.

Just going to throw this out here....

What is the difference between a Voxel game, and all the other games I play?

So basically, 7 Days to Die is more CPU-intensive than any other game you used in your comparison. So you're comparing apples to oranges.

I really think something is wrong with your setup there.

I'm running an i7-3930k overclocked form 3.2GHz to 4.2GHz with a Evo 212 Air cooler, and I rarely get above 55C.

Also, your supposed 50% downclocking actually would impact performance of the client quite severely. Here's some testing I did that shows clock speeds make quite a difference.

 
@KingMigi There are two sensors for the Ryzen 7, and the proper sensor (the tdie) is actually 20' lower than is being recorded.

This makes the 'actual' temperature limit on the proper sensor, 75, not 95.

There is a lot of confusion over the Ryzen 7's sensors.

Do not be so quick as to presume a person posting isnt knowledgable about something you have not fully researched yourself. I mean that in the greatest respects, the default sensor for the Ryzen 7's, falsely record at 20' above their true values.

XD Don't be so stuck up. I specifically pointed out that I don't know if that particular point is true or not.

But that begs the question, if you were aware of such a thing, then explain to me why you wouldn't point that out in your original post so that people weren't confused as to why you'd be complaining about 72c?

Especially since the Ryzen models that do use an offset give multiple temperature readouts (Tdie and Tctl), one of them being the actual readout, which would've read "92c" for you.

Wouldn't one knowledgeable of such a thing make sure to denote that it's actually running @95c and that 75c is only the thermal shutdown for a model with a -20 offset? Especially considering most benchmarking and user discussions use the actual temperature readout rather than the offset one? They sure would... Speaking of diagnostics!

The overwhelming majority of popular diagnostics programs today (and honestly since early/mid 2017) have since compensated for the 20c offset, even Ryzen Master has done this, and read back at the proper temperature (i.e. the higher temperature). What diagnostics program are you using?

Sounds like a "I totally already knew that" situation to me! lol

Regardless, your issue is on your end, and not with the game.

I use HWINFO64. I used to use Open Hardware Monitor but it hasn't been updated with Ryzen support. I am reading and recording my temperatures properly discluding the false 20' overhead.

Are you here just to cause drama? You seem to not be interested in talking about the actual topic, and are more interested in trying to cause an arguement about CPU's or discredit someone at random, which has nothing to do with the point of the topic. If you have nothing on-topic to contribute, please move along. Further posts on this pointless arguement you are trying to create will be seen as attacking a thread/trolling/attempting to cause drama.

I've repeatedly directly addressed the topic, you just don't like the answer. The answer is: It's a problem on your end, not with the way the game utilizes CPU. I've ended both of my previous posts with that exact assertion and my reasoning for believing that.

However, you're obviously not as interested in the topic as you are in defending your credibility, given that the only person you've addressed is me and you are of the belief that I've only talked about your credibility. SylenThunder up there posted something and didn't mention your obvious lack of knowledge at all.

Kind of interesting that you'd ignore my points about your topic, then chastise me as if I hadn't talked about it, but then ignore the person up there ONLY talking about the topic. XD

AIO's are crap. Replace it with a good air cooler.

7 Days doesnt care if you have 2 core, 4 core or 8 core. All it cares about is how fast a single core can go.

Its always going to be CPU bound. Such is Voxel life.
