Let's not over complicate things: HT enabled - increases the responsiveness of the system overall but leaves it wide open for problems if we are not careful. It can only affect the fps a little, the stability increases with the correct setups.

More cores = multiplying the situation - and so enhancing all aspects of enabling HT - good and bad.

"Thread affinity forces a thread to run on a specific subset of processors. Setting thread affinity should generally be avoided, because it can interfere with the scheduler's ability to schedule threads effectively across processors. This can decrease the performance gains produced by parallel processing. An appropriate use of thread affinity is testing each processor."

From the manual.

This is not speaking of the AM value we might set in P3D cfg.

This is saying in general an app would not require any worry about affinity as it might interfere with the way the jobscheduler works to keep things evened up. So what about those apps not included in General, like P3D. Those apps might allow tasks to split out particularly to obtain better throughput from another core, like P3D. In HT mode that next "core" might only be the sister LP of a core, the task is still on the same core - not what's intended. FSX and P3D go about avoiding this problem in different ways but similar approaches. In the end it's better to help them and the other apps we run or we find problems arise as often there's no logical way the jobscheduler can sort it out.

Hi everybody,

 

I've read this very interesting thread and I'd like to revive it since I'm considering an upgrade for my nearly 2 year old config.

I don't know a lot about all this stuff so please feel free to provide as much explanation as possible 🙂

I think I have a pretty decent config (see below) but I'm experiencing low FPS when I run heavy add-ons (the lot of many people I guess). But on top of that most sceneries take a lot of time to load: I get a lot of blurry pictures and black buildings when I approach my destination airport. I'm unable to fly at dawn or night with all that dynamic lighting. I'd like to solve (or at least improve) that. I've tried to tweak the cfg file and play around with the options but found no compromise that really suited me.

PC config: 7700K 4,2 GHz - ASUS Z170 Pro Gaming - 32 Gb DDR4 3200 MHz CAS16 - Asus GeForce GTX 1070 STRIX OC

After a bit of reading I zeroed in on two possible options: overclocking and PC upgrade. Apparently the 7700K is not very stable and overheats, and so Intel advises not to try overclocking it (funny for a K series designed to allow just that).

So I'm thinking of upgrading. Here again, two options:

- CPU upgrade. After reading your posts, I could upgrade to a 8700K (or a 8086K) given how well these CPUs fare on the tests (or even the new 9900K / 9700K where they are out). However I don't really know the FPS gain it would yield on P3D4.

-GPU upgrade. I could benefit from the rolling out of the new RTX 20 series to buy a 1080Ti at a discount, or even a 2080Ti if it turns out that this cards is able to make a difference in P3D4 compared to the 1080Ti.

I could also go for both solutions.

What do you think?

Thanks for your help.

Matt

my puter has none of that. furthermore, I'll bet I'm running higher settings than you are ...<as he> drops mic and walks away.

You'd gain very little by changing your 7700k for an 8700k - see https://www.guru3d.com/articles_pages/intel_core_i5_8600_processor_(65w)_review,7.html for a single thread performance comparison. For the IPC graph, the 7600k would be directly comparable to your 7700k. As long as you have a good cooler you should be able to comfortably overclock to 4.7-4.8GHz. With regards to your GTX 1070, unless you're running at 4k resolution, upgrading to a 1080ti (or an upcoming RTX card) is unlikely to make a significant difference in P3D.

You already have a good system - you probably just need to fine-tune it.

You speak to real world experience? ....meaning you can draw meaningful opinion from your existing kit (or any other source for that matter) to conclude that a tuned coffee lake is not superior (on a significant level) to a 4 core previous generation platform in the P3D v4.3 world?

Did you look at the single thread benchmarks in the link I posted? The IPC benchmarks were carried out at the same clock speed and showed virtually no difference between the 7600k (read 7700k) and the 8700k. The only advantage that the 8700k has is a slightly higher stock speed. You'll get a very slight improvement from the newer chipset but probably no more than about 5%. If you were to talk about multi-threaded applications then you'd be correct that the 8700k is the better CPU but P3D (even v4.3) is still primarily a single thread application.

gimmie a few minutes ....i'll post some meaningful real world numbers with "default" settings.

the default settings on my rig.  real performance based scores not a dummed down config - like you see with the 99.9% ''''internet hardware review/benchmark"""" posts.

My scores (the 8600k) are with cpu and memory bios presets. I have never had a blue screen, system or app fault with the mentioned bios presets (the presets are my fall back settings not benchmark settings.  the bios presets will run P3d with above average settings in the mid 70c range ...nothing in this is exotic -all hardware is readily available. note: the inked out areas are speed and timings that I feel are irrelevant ....because this a ""default""" test.

 

Right but to what extent are these scores relevant for P3D/Xplane?

I saw on AIDA64 that my GPU almost never hits 100% utilisation, whereas the CPU is nearly always at 100% with temperatures above 90°C (194°F).

If I put some watercooling in place to overclock the 7700K would I see a difference in FPS/loading time for sceneries?

Going from a 7700K to a 8600K also requires changing the motherboard... and potentially reinstalling the sim, which I'd rather avoid...

Well, you can't in any direct way. One must draw his or own parallels (or connect the dots) with P3D 4.3. Frankly, I was mocking the info that Vortex posted.

Well, that could depend the settings you use ....but, I can tell you that in a unlimited frame per second environment my system will bury the 1080ti. Imagine six cores running at 5 GHz. oh, and that's the beauty of the coffee lake ....I'm doing 5 Ghz on six cores, no delid, with spike temps in the mid 70c under a $100 cooler ....with no avx offset! ...i'll leave out the 3200 memory  running at 4133 stuff ....don't wanna rub it in.  In game settings using frame rate locked at 29 with vsync on, you ask? take few degrees C of the spike temps because my gpu temps drop from 70c to the 58c - low 60c range.

re: water cooler- I don't know what your best course of action is but,  you do need to get those temps down ....a cool cpu is a happy cpu.

yes, upgrading to the coffee lake will require a new mobo ...but don't order now ...get the coffee lake refresh, such as the 9700k, due to be released in a matter of weeks  -you wont need a water cooler. Also,  reinstalling the sim would will be a small price to pay after you realize the return on investment.

Why did you ink-out the clock and memory speeds in your benchmarks for the 8600k if it was a default test? If they were irrelevant, why not show them as you did the others?

You said in a later comment that you were "mocking the info that Vortex posted" but I have to say that I'd be much more likely to trust Guru3d than your results. They have actually tested all of the CPUs in controlled conditions and, in the case of the IPC test, at identical clock speeds. Have you? These results also closely match the single thread performance benchmarks on most review sites. The 8700k will obviously perform better in multi-threaded benchmarks as it has more cores and a higher stock speed but single thread performance is still significant for P3D.

Hi,

I posted this in another threat, but maybe ist better suited here:

I'm looking for a new pc,as my I7-5820K is aging and as I fly P3D in VR only, I need every bit of firepower I can get from my new PC.

So I'm either going the I9-9900K or the I9-7980xe/7960x route. What to you guys think will perform better, with a descent watercooling and overclocking?

I know the I9-9900K is not even out, just heard the current I9 is a great CPU and the Level3 cache and cores might play a big role...
