i7-8700 System Stutter Still, Setting needed

[nicboyGS]

Hi

I have a a i7-8700 GTX 1070 system,  my setting including Affnixmask = 3028 and TEXTURE_BANDWIDTH_MULT=120 following suggestions from the forum. But I got stutter whenever I look around and some AI aircrfats tend to have black texture and took long time to appear. Can anyone please suggest what's the setting for i7-8700 six cores to get ride of these issues.

I'm not an PC expert so not sure about how to figure out which cores/threads to use, please jsut give me a number which you feel it is the best under AM.

Thanks a lot.

If your having problems with such a good processor, I’d be removing the affinity mask altogether. Whilst you’ll find some affinity mask fans around avsim, there’s very little evidence that they help and as far as I know, LM doesn’t specifically recommend there use.

whilst I tinker with affinity masks from time to time, I current fly with all cores and threads active.

What happens when you rebuild the P3D.cfg (i.e., go back to the default settings)?  When tweaks and extremely high settings in the P3D.cfg are causing stutters and black textures, that's what I would do.  I would want to find out if it were the settings I used.

Microsoft Windows 10 uses all cores at 100%.  Can't get better than that!

You should remove all of your tweaks out of your .cfg file.  

I have a similar i7-8700k system and AffinityMask does my new rig more harm than good (I have tested).  Yes, I used that (and other) tweaks on my old system, but this 8700k seems to work best without them.

Since you are not a PC expert, you are in luck.  P3Dv4 + 8700K + 1080ti requires no tweaking at all.

So I removed the Affinitymask setting and cleared the Pre3dv4.cfg. seems much better in fluidity but the graphic is not that good. I will try other settings hopefully to make it better.

So looks like Affinitymask is a big drag on the performance.

Same here I have a 8700k I removed the affinity mask. Are you running 4k monitor??

Tooting I just noticed your profile picture LAMAO!

Disable hyper threading. It is useless with this number of cores and you can go higher in overclocking with moderate temps. And also, don't think that more threads means better performance in such a case.

Affinity mask may be useful to reserve one core for the system and services.

I've tried running my 8700K with HT both on and off and I am currently running with it left on.  My 8700K is running at the stock 4.7 GHz turbo mode and my temps run up to 80C, which I find quite acceptable in that those are peaks not norms. The OP did not mention the GPU being used and I am finding that P3Dv4 will load both CPU and GPU if the capacity is available.  I am very happy with my latest build:  8700K 4.7GHz 3600 MHz DDR4 2x1080Ti and I'm using the tried and true H115i cooler with aftermarket fans for it and the case.

Agree Patrice that HT off will allow you to run a faster overclock, but be careful that you do not take this to mean that running with half the number of logical cores is better if it is cooler.  Of course it is cooler, each physical core is working much less harder.  The measure of work done cannot be directly measured by the heat produced but it is a pretty good secondary indicator.

Intel Cpus do approx 25% more work with HT on, think AMD Ryzen is close to 30% but they have not as good IPC and overclock poor compared to Intel.

Are you using the paste that came with the cooler?  I would recommend getting a high quality 3rd party paste.  I did that and the temps went down quite dramatically, similar setup to this.

HT off for me if the way to go with the 8600k and P3Dv4.  With it on, the main FS process takes 100% of it's first logical processor for the core and only a small % spills into the second logical processor for that core.  With it off, the main FS process doesn't take the whole core.   Interested to hear if others have different results.

I can't test it now, my GPU is dead, i should get the new one next week. I tested this with FSX only a couple of years ago, and i belive i had much better texture loading with HT on, especially terrain. I can't remember why i decided to use HT off, maybe stutters or something i've read about - maybe about single core performance being most important for FS. 

I like your expertise, so my question is - In your opinion, is there a benefit for P3Dv4 from this 25% more work? If so, maybe even lower OC with HT on could be the better option for P3D?

I'm asking this becouse the the main argument against HT ON is the heat an lower clock. Interestingly, i saw only a 2-4C increase in temp with HT ON, and OC remained stable

The H115i comes with a layer of stuff, which one needs to promptly clean off using a surface cleaner or acetone.  This last time I used Arctic Silver Ceramique, but a review by Puget Sound Systems found negligible differences between products, and how applied seemed more important.

There is nothing wrong with core 0 appearing to have 100% loading and rest of cores not as busy. Test it yourself, use something like Process Explorer to turn off core 0 for a minute then turn it back on and all cores will be more equally loaded; however, there will be no difference in performance.  When my CPU is heavily loaded all my logical cores except core 1 are pretty much equally loaded, but the load has to be above about 80%.

I don't have the same credentials as westman but I only see a marked increase in temperatures on the 8700K when pushing 5.0GHz, which is in agreement with the various tests and reviews I've seen on this chip.  I've run at 5.0 and 4.7 GHz and I cannot subjectively see a difference, I'm sure it might be measured but it's not noticeable.

Thanks, but i'm not sure from your response, i actually asked if it's worth for P3Dv4 to go for lower overclock with hyperthreading ON.

BTW, i see better smoothness with higher OC, even with 100MHz increase. But this can be subjective - i'm sure, but cannot provide evidence. Like with better terrain loading with HT ON

Are you sure?  The information I had on this cooler was the the heat transfer material was pre-applied and all you had to do was install it.  My temps are very low (stock 4.7 overclock).
