July 10, 20187 yr 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.

July 10, 20187 yr Author 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.

July 10, 20187 yr Author Does the Gatwick call go up to 10? I’ll check again. Neil Gardner n.gardner952@btinternet,com Wisbech, Cambs
July 10, 20187 yr Commercial Member No magic to this, it's just a straight binary to decimal conversation. Just remember that Core 0 is the furthest to the right. https://www.easycalculation.com/binary-converter.php Dave Hodges System Specs: I9-13900KF, NVIDIA 4070TI, Quest 3, Multiple Displays, Lots of TERRIFIC friends, 3 cats, and a wonderfully stubborn wife.
July 10, 20187 yr For smoothness, locking the FPS to 20 w/ VSYNC on & Triple Buffering on, works well for me.
July 10, 20187 yr Author Thanks guys - got the figure: 1048575, Gatwick call gave me binary and calculator converter binary to decimal gave me the final figure. Neil Gardner n.gardner952@btinternet,com Wisbech, Cambs

July 10, 20187 yr 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. Dan Downs KCRP

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. 4 hours ago, pracines said: For smoothness, locking the FPS to 20 w/ VSYNC on & Triple Buffering on, works well for me.

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
