An Affinity Mask for an i97000x

Recommended Posts

Hello all

 

I have project lasso, I have - much against my better nature - overclocked my CPU very slightly, Ive monitored the way P3Dv4 utilises the i9 and there are certainly high load times when virtually all cores are employed, but also long stretches when they are not and yet there are stutters and stalls in high load areas.  Ive wondered about overclocking my card, and all to get P3D to operate smoothly, every other game I have is smooth as silk, as ever flight sims are always the most hungry. I am still not convinced that P3Dv4 utilises my hardware as fully as it should, but can only think of affinity mask as a means of getting it to do so. I am, therefore, wondering if there are any of the clever people out here, who read this post, who is able to calculate a figure for affinity mask for an i9. Ive tried to understand binary, and how to calculate it for myself, Ive tried the 'Gatwick' calculator but of course it does not go up to a 10 core processor, 20 with hyper threading. If anyone can help I would be very grateful. Thank you all.

The Gatwick calc DOES go up to 10 core.

Sorry, I should add that the performance I seek is smoothness. I remember a brief period back in P3Dv2 when I was taking off from Heathrow in a PMDG 737 with just 20-23 FPS, and it was beautifully smooth. Oh to recapture the moment.

Does the Gatwick call go up to 10? I’ll check again.

0-9 is 10---- don't be tricked by the number 9 because 0 is counted as a number.

For smoothness, locking the FPS to 20 w/ VSYNC on & Triple Buffering on, works well for me.

Thanks guys - got the figure: 1048575, Gatwick call gave me binary and calculator converter binary to decimal gave me the final figure.

No AM , no HT

Rob A has a 7900x and he had the best performance/smootness without custom AM and without HT.

Myself , I have a 7940x and the same for me : no custom AM and no HT

I too find running no Hyperthreading was the best way to achieve smoothness.  I would stop worrying about afinity masks...

Ditto - I have a 7700k and use no AM or HT - I get my best results with that setting.

Ditto.. no AM/HT off (8700K).  Stutter is not caused by clogged up CPU or frame rate, it is the result of delays doing a specific task such as loading scenery objects.   Scenery designers such as Flighbeam's Mir know how to minimize this and hopefully each new minor revision to P3D will bring better multi-threaded performance.

I don't completely agree with that.  If you load up your main core to 100%, say by progressively moving the autogen sliders to the right, it's pretty clear that stuttering sets in when the CPU starts coming up against the 95-100% ceiling.  Same for GPU performance as it (or they) approach 100%.  Stuttering happens when frame production becomes erratic for any reason, and an overtasked CPU or GPU can definitely cause it, as well as other bottlenecks.  The bottleneck itself could be excessive processor demand, waiting on memory or bulk storage, process swapping on the virtual cores, thread locking etc.

If I had to lock a $900 10-core i9 to run at only 20 fps I'd be fighting the desire to stick my head in an oven.  😉

It all depends on the sliders - I keep very high settings and run very many add-ons with PMDG, A2A, Flightbeam, Orbx, ASP4/ASCA, Envtex, GSX, UTLive @ 85%, ect. ect...

I can set unlimited to get about 30-50 FPS but I prefer a smooth and solid 20 FPS, and it looks very realistic; no unrealistic bare spots and its full of life.  

I will not lower sliders to have 24 or even 190 FPS.

I think this way because I'm an aviator first, and the appearance/immersion of my flight sim far outweighs my ability to boast about high FPS like gamers/PC gurus tend to do.

keyword...trade off
