Post as a guest Name. Email Required, but never shown. The Overflow Blog. Socializing with co-workers while social distancing. Podcast Programming tutorials can be a real drag. Featured on Meta.With increasingly demanding games and streaming needs, many people struggle with the constraints of slow hardware. Hyperthreading is there to help in these situations.
It increases the speed of your CPU, but there are some downsides you have to take into account. There has been some speculation that hyperthreading on Intel CPU can make your system vulnerable to hacks. Intel claims that this is not the case.
On the other hand, there are some models that are hyperthreaded by default and you need to disable the feature from the BIOS. The exact steps for disabling this feature may vary depending on the system you are using and the CPU in question.
The following section provides some basic steps that apply in most cases. As mentioned, first you need to enter the BIOS. This depends on the machine you are using. On some models, you just need to press the Delete key on boot up.
Once inside the BIOS, you need to navigate to the right host for the given system. The label you are looking for is Processor and it might be located in one of the sub-menus. Take your time until you find Processor and then hit Enter to access the settings. When you get to the Processor menu, select Properties. In most cases, a dialogue box will appear, allowing you to choose to turn hyperthreading off or on.Is cesium nitride ionic or covalent
After you disable the feature, go to the Exit menu and select Exit Saving Changes. The name or layout may differ on your computer. For example, you navigate to Logical Processor instead of just Processor.
Simply put, hyperthreading creates more room for your data to travel. Once you enable the feature, you allow the data to move along two tracks instead of one. The data gets separated and then processed by the computing depot, which makes your computer run faster. Without hyperthreading, your processor gets one program per core at the time. Hyperthreading means you can get multiple programs per CPU, which allows you to basically turn each core into two processors.
The system that provides this is called parallel computing or superscalar architecture. This means your computer is able to cope with several instructions from multiple threads or tracks. Having more cores on your CPU means faster processing.
The more cores there are, the less likely you are to need hyperthreading. But make sure you know the real facts about the hardware you have. For example, Intel hints at the number of cores by labeling its processors i3, i5, i7, etc.
But in reality, you only get four cores on some i7 processors, and i7 Core processors from the Extreme series may come with up to eight cores. For gaming and streaming purposes, hyperthreading usually does the trick. However, the speed might not improve in other applications. In part, this is because certain programs cannot efficiently send multiple data strings into a threaded core.
This article should provide you with enough information to avoid trial-and-error when disabling hyperthreading. You can easily turn the feature on using the same steps. The important thing to note is not to rush things with the BIOS, especially if you are using it for the first time.Please share your forum-specific feedback and bug reports in the Forum Feedback community.Wiley chapter 6 answers

Even though the original video has been removed for some reason, some of the other posts could be helpful. Also, I wouldn't doubt that it's the game itself in Early Access and not fully released with full optimization.
I'm just assuming that when more optimization comes out and the game is in full release, it will be much better. For example, meeting the minimum requirements and running at 4k is not going to work out very well.Emilio cartoni
The screenshot above is my settings. And they run pretty well for my computer. It still would be helpful to know what hardware you are using to make a good assessment. Like stated by franca, this game is still in early access and they are still working on it. Most of us have high hopes for when they implement unity Unity will be an updated version of the engine and might run a lot smoother than it does now.
If you watch streamers like Kotton who has decent hardware has the same problems. His fps doesn't go far above mine and he has better hardware than I do. I dont know what Kragar said is true because my cpu doesn't have HT on it i5 k so i cant confirm nor deny this.
I've done a few things like the DPI scaling trick and the thing that was linked above with changing Nvidia Control Panel settings. It's mostly just the game. Running on Unity and not being optimized yet is the biggest issues that I've seen. If you have more lmk I can send you the correct. FilteringZ-Bur, Chromatic aberrations and noise.

Posted June 23, Share this post Link to post Share on other sites.Back in a day, most computers were desktop machines with the main goal for the hardware, to offer absolute best performance and there was no real need for technologies such as SpeedStep, Turbo Boost etc. However, in the modern world, power consumption sometimes takes a higher priority than performance output.
Even though these are all positive changes, it sometimes creates a situation where an end user is not getting top performance when it is required delayed performance boostboost.

This can be caused by many hard to predict factors, such as system state, availability, CPU state, heat and many many more. This application was made to provide help in controlling such factors and reduce the effect of degrading performance when possible. Many features mentioned above will be described in greater details in the description below, so if you are interested read on The processor power management PPM engine and the scheduler work together to dynamically adjust the number of cores that are available to run threads.
The PPM engine chooses a minimum number of cores for the threads that will be scheduled. Cores that are parked generally do not have any threads scheduled, and they will drop into very low power states when they are not processing interrupts, DPCs, or other strictly affinitized work. The remaining cores are responsible for the remainder of the workload. Core parking can potentially increase energy efficiency during lower usage.
The problem with Windows way of core parking is lack of flexibility since by default you are given very few options for setting Core parking index on your machine. Here's an example of how core parking actually works and the meaning of an index number:. Now for example we would like that 4 cores out of 6 to never be parked by the OS regardless of the load.
This will tell the OS that it can only park 2 cores out of 6. I hope this'll help explaining how it works. Latest version: 3.

Get Quick CPU.Intel clarified that it's not recommending everyone to disable Hyper-Threading, but that some of its customers should consider the option depending on their security needs:. This includes customers who cannot guarantee that trusted software is running on their system s and are using Simultaneous Multi-Threading SMT.
In these cases, customers should consider how they utilize SMT for their particular workload sguidance from their OS and VMM software providers, and the security threat model for their particular environment.
Google seems to be one of those select customers which considers the risk of keeping HT enabled just too big. For the majority of our users, whose workflows are primarily interactive, this mitigates the security risk of MDS without a noticeable loss of responsiveness.
Chrome OS 75 will contain additional mitigations. Intel unveiled yet another speculative execution side-channel flaw in its processors.
Intel believes that in order to protect users against this speculative execution issue, Microsoft and other operating system vendors, hypervisor vendors, as well as Intel itself will need to implement significant changes in their software.
The solution will involve clearing microarchitectural buffers when switching to software that is not trusted by the previous software.(11.7) TARKOV FPS BOOST OUTDATED! 0.12 GUIDE IN DESCRIPTION - Escape From Tarkov
For instance, every time a processor would switch from one third-party app to another, from a Windows process to a third-party app, or even from less trusted Windows processes to more trusted ones, the buffers would have to be cleared or overwritten. Adding such a significant step in the processing software will most likely lead to a performance loss. How large or small, it remains to be seen, but chances are it could be on the significant side.
The company admitted in its white paper that the software mitigations will have a significant effect on how HT works. The threads will need a higher level of isolation between each other, and they will not be able to run processes from different security domains anymore.
Threads from different security domains will simply become idle thus turning into wasted processing power. Intel itself seems to be moving away from Hyper Threading lately on some of its best CPUs, even in the face of AMD competition with both higher number of cores and simultaneous multithreading SMT support at similar price points.
Intel has also been publicly reluctant to agree with the disabling of HT when others have called for it with the discovery of some previous CPU flaws, but in its paper, the company stated that disabling HT altogether may be warranted as protection against MDS attacks. Despite all of these drawbacks, Intel did mention in the white paper that these software mitigations are highly recommended, despite the vulnerabilities being classified only low to medium severity. Intel noted that future processors will have data sampling methods mitigated in hardware.
Motherboard and laptop OEMs tend to update only their most recent products, so the majority of systems sold in the past 11 years will likely remain vulnerable. Those who buy the new Intel chips starting with Whiskey Lake refresh and later should see a much lower performance loss as well as the security protection from the built-in hardware mitigations, at least until a new speculative execution attack appears that can bypass the new mitigation appears.
Intel has provided more information about the MDS flaws, including about how to get the software patches, on its website. Intel Recommends Disabling Hyper Threading The company admitted in its white paper that the software mitigations will have a significant effect on how HT works. See all comments So those with 8th and 9th Generation CPU's are fine.
Another day another Intel security flaw in Hyper Threading. It is really amazing how insecure HT is. Coffee lake is 8th gen. All the more reason to buy AMD Very likely. Our attacks affect all modern Intel CPUs in servers, desktops and laptops. This includes the latest 9th-generation processors, despite their in-silicon mitigations for Meltdown. Ironically, 9th-generation CPUs are more vulnerable to some of our attacks compared to older generation hardware. Wow, core i7 people will now have core i5's and core i5's on older laptops will now have dual core i3 computers since they were dual core hyperthreaded parts.
