Update: You can find an updated and significantly improved version of this post in my book "Pro. NET Benchmarking". In the previous postwe discussed DateTime. This structure can be used in situations when you don't need a good level of precision. If you want to do high-precision time measurements, you need a better tool because DateTime has a small resolution and a big latency.

Also, time is tricky, you can create wonderful bugs if you don't understand how it works see Falsehoods programmers believe about time and More falsehoods programmers believe about time. In this post, we will briefly talk about the Stopwatch class:. If you are not a. NET developer, you can also find a lot of useful information in this post: mainly we will discuss low-level details of high-resolution timestamping probably your favorite language also uses the same API.

As usual, you can also find useful links for further reading. It is an internal bit register present on all x86 processors since the Pentium. On Windows, it can be read directly from C code with help of the following asm injection:. On modern hardware and modern operation systems, TSC works well, but it has a long history and people often consider TSC as an unreliable source of timestamps.

Let's discuss different generations of TSC and problems which we could get with TSC you can find more information about it in the manual, Vol. The first version of TSC see the list of the processors families in the manual, Vol. It's not a good way to measure time on modern hardware because the processor can dynamically change own frequency e. If a thread starts measurement on one core and ends on another core, the obtained result can't be reliable.

For example, there is a nice bug report on support.

Multi core or multiprocessor systems may encounter Time Stamp Counter TSC drift when the time between different cores is not synchronized. The operating systems which use TSC as a timekeeping resource may experience the issue.

It's a good step forward, but Constant TSC still has some issues e.Log in or Sign up. BukkakeSep 18, How do you test if its enabled in windows? HonoredShadowSep 18, Last edited: Sep 18, ProphetSep 18, IcESep 18, WhiteLightningSep 18, It is on by default on my PC but its not doing anything then?

Is it best on or off in bios and windows?

Papa ne seal toda story

Well I did try with it off in the past and what i saw happen with DPC Latency tester was that my overall latency idle was done consistently but when I did do something like load a game or open firefox etc. This was all of course without me knowing that I had to enable it in Windows which I have no clue how too!

I'm sure I already had a thread on this. I think I added to the discussion in this thread. Snake oil. NoisivSep 18, PhazeDelta1Sep 18, Not exactly placebo. When I enable it in windows and get It is smoother but everything is somewhat slower and delayed.

The difference is very noticeable for me and some other people have reported the same thing on neowin forums. And regardless of the windows configuration enabling it or not in the bios makes a slight difference in terms of DPC latency apparently windows uses different timers by default so disabling HPET in the bios means one less conflicting timer to use and lower DPC latency. Why don't you just try it for yourself? It's harmless and easy to revert the changes.Discussion in ' Player Support ' started by geiselOneMar 8, Log in or Sign up.

The game is just poorly optimized. I haven't seen any performance improvements with it on. But with this and hpet off, I'd like to think it helps smooth out the game against microstutter and reduce input lag. Even if its an inconceivable amount. I wouldn't say it's a great idea to run it for Planetside 2 though. TownCryer8Mar 8, Sounds like bloatware to me.

Suspicious in itself. The problem the crysis video in said link ,appears to be addressing is getting more actual information to the SLI system he has by speeding up how quickly the CPU processes the drivers and sends cache's of info of what to render, to said cards. Thats largely not PS2's problem when fps tanks and your CPU is limited, your CPU is just struggling to keep track of a zergs worth of player entities, and keep the game world logically coherent something its hard to mutlithread.

Thus, I'd be skeptical, certaintly too skeptical to drop 10 Auzzie bucks or whatver the price of 'click to make go faster' software is. Also, be careful. Messing around with the internal clock could potentially cause desync issues, or in fact worse frame rate.

I've seen both now with my involvement in the various 'desync' issues threads. I'm also not entirely convinced 'hypermatrix' knows a huge amount about what he's talking about.

In contrast to what is indicated on the website, the free version works on 64 bit too. I gave it a whack - no noticeable difference. ZcuronMar 8, I'll give it go.

On Redstone 4 I have 3. No modification in bcdedit on both systems, hpet off in bios. Bug or what? Please guys check this if you have new update and some time. Last edited: Oct 3, MustangOct 3, So is this a feature or bug in ?

I am seeing 10mhz with HPET enabled in bios always had it enabled. EdKieferOct 3, You can imagine that if a time sample is subject to variable network delay among other unpredictable network challenges and we immediately stepped the clock to match every time sample, the clock would likely be incorrect fairly often — it could even move backwards — a problem that would certainly make for a rainy day in the life of an IT Pro… Instead we take multiple time samples, eliminate the outliers, and discipline the clock with the goal of bringing the system closer and closer to synchronization with the time server.

Disciplining the clock entails making adjustments to gradually converge on the correct time.

Ultimately there is a natural limit to how small of a change we can make but the key is that smaller is better. Just how granular can we get? This is a complicated question but is based on the frequency of the QPC clock. For a more in-depth look at this subject including QPC, please reference this article. Previous versions of Windows allowed for a QPC granularity the smallest change we could make to the system clock of 6.

This is akin to the difference in clarity between p and 4K television. There is much finer granularity in the 4K picture! So why does all this matter? Well accuracy as measured over time is reflective of your stability; not only can we hit the bulls-eye, we can hit the bulls-eye over and over again. However, only one of the 60 measurements is saved, the one with the shortest round trip delay. This method is based on the assumption that NTP measurements with the shortest round trip delays provide the best estimate of the true time difference.

So that's it then, we're stuck on 10mhz clock? To be honest it doesn't seem to be affecting performance or anything, just a little concerned that it's locked at this speed.

That all changed today as I received input from an expert in regards to the useplatformclock tweak. IMHO it is very important to read what he has to say. The full email exchange is at the bottom of this post. I cannot reproduce results others mostly overclockers are seeing with this.

Please read the 2 email conversations at the end of this article. For me, this issue is now closed. They are: useplatformclock, tscsyncpolicy, and disabledynamictick. Opening Statement These tweaks have been mentioned in some places and to me as performance tweaks. I set out to see if they were. The commonality they share is they are setting that involve the system clock.

In general Windows will use the best timer your hardware supports and may use a mix of timers. Fastest can mean errors. These settings can harm battery life.

By default Windows 7 uses different timers in the CPU to calculate stuff.

HPET is the newest and best of these timers, but because of default combination of timers it takes longer time for CPU to keep up all the timers and sync between them.

The higher the QueryPerformanceFrequency is the better is performance. You only get high frequency with HPET. The other timers will give you significantly less frequency.

Also note that if your ratio is not 1. Online games is a good example of boost from HPET. A guy on another forum claimed that by disabling ithis DPC latency plummeted and his gaming performance improved; most notably the microstuttering. So I tried it myself, and the difference to my astonishment, was very noticeable. First off, my DPC latency dropped big time.

Not that it was high to begin with, but now it hovers below 10 for the most part. Second, I noticed that general windows performance felt snappier. I know I'm not imagining things, because like many, I scrutinize my system so I'm sensitive to even minute changes in performance.

And last but not least, gaming performance is definitely smoother. Anyone with SLi will tell you that occassionally when playing a game, you experience a bit of lag or stuttering for no apparent reason whatsoever. Most people attribute these minor discrepancies to SLi, but what if it's something else?

There's a possibility that having it on could increase the amount of microstuttering in any given game; particularly if you're running SLi. You need to force HPET only and reboot. People don't know about that Windows needs to be forced to use HPET only - that's why the bios setting alone can undergrade their performance. This "tweak" is depending on each hardware setup. Best thing to do is try it for yourself, do some benchmarks and see what happens, if your system runs fine now.

Leave it alone would be my advice. I had mouse ghosting and other nice things when doing it "your" way. It seems to have had the opposite effect here too. Without it, my clock ratio was mostly 1. After setting it my clock ratio is mostly 0. Here's the original post from the author of WinTimerTester 1.

It explains the scenario better. Seems to be related to software overclocking utilities. Funny as I don't have any problems like that. I do use CRT monitor. Disabled it because lately my computer has hard locked twice while browsing the internet hasn't done it in awhile though. Either way my system seemed more responsive on boot than usual, won't be able to tell if it helped until I get a chance to use it more or see if it freezes for no reason again. I have 5?

There is nothing else concerning this that I can 'adjust'.
