@Dirk98 I think I've just got what I've been looking for since 4.4. 4.4 has been running so well. Been enjoying the PMDG -8 and the NG. But not been enjoying the FSL 319 at all, to the point last week I deleted it. It did not matter what I did I could not stop the nasty FPS jumps from my Locked 26 to flashing to 7-8 FPS or more often 14-18 FPS. It was almost rhythmic to watch it, I looked out the VC at 90 degrees to the left. It was very frustrating. After all the testing above and settling on AM=85, I took a deep breath and installed the FSL A320/A319. I stopped the app from removing my AM. Now what I've seen in all my tests with the NG/-8F is with AM=85 only 3 cores work hard and core #3 (01,01,01,01) like I said above sits at 25-30%. I loaded up my test flight once more and repeated the same test I always do. But this time the FSL ran like a dream. Because I was watching all my cores at work I saw one huge difference from the countless testing with all other aircraft. Now Core 3 was working at around 75-80% constantly. Never dropped below 70 and never went over 90%. I can only conclude that having no AM was bottle necking the cores that the FSL used/needed. But with the AM it's freed it up and what a difference it makes. Am now so happy I read @SteveW finding and along with your thoughts, doing so has not only freed up a few more FPS but more importantly made the sim run so smoothly even with the FSL. Just to finish off, I took of from EGNX my home airport and the one I use for all testing. I turned south to run the sim and watch what was happening at a height of 10,000ft. I Ended up close to Aerosofts EGLL, I turned to swing by it, to the south but very close to it, then flow right over the city of London. FPS never dropped below my new LOCK 28 FPS for the Bus. If it can handle EGLL and the city of London that's as good a test as I need to do. Thank you both very much. You have made me very happy with my sim. I just wanted to express my gratitude to you both.

Hi Dirk. I just spent an hour testing AM=250, I had more cores working with AM=250 ofc but with high P3D setting the active cores were maxing out and I got texture loading problems. AM=250 was a bit smoother, but I went back to 85 as only 3 cores are working hard plus 1 around 25-30%, but unlike AM=250 the cores topped out around 85-90% with no bad texture loading. So thank you for the thought and I enjoyed testing AM=250 for myself. Cheers David.

I don't have the CS 75 but wow he has done a great job on the sounds. Topman Alex.

Am on W7 and I set all Affinity through task manager, The ones that start with P3D need changing as they show are using the same AM as P3D so I change them. So Yes I make sure everything is using what I won't. BTW you say that even when 11.11.10.10 P3D is still using the red ones, but when I fire up P3D with AM 85 01,01,01,01 only the "1" cores in task manager show are working all the "0'" show nothing. So I still dont understand how P3D can be using a core that in task manager is showing nothing happening worth talking about.

Hi Dirk, Thank you for all the above.

Hi Dirk, I would like to discuss this because I would like to understand it more. Firstly I did another flight last night with 01,01,01,01 for 4.4 and all apps on 10,10,11,10. I also did my normal FPS test and found I have gained 7-10% FPS. Very happy with this setup. My PC shows 4.4 is running really nicely with these setting. What I don't understand and would like you to explain so I understand the logic behind it, is how the setting you post work or more importantly could/should work better. Let's start with 11.11.10.10 (JobScheduler 250) This takes P3D off the first two main cores but leaves it using the first two HT LP's. I have read many times that taking P3D off the "0" is a good idea but why off "2" also? What I really don't understand is 10.10.00.00 (JobSch 160) and 01.01.00.00 (JobSch 80). This looks like a really weak way to run apps. 01.01.00.00 looks better, but when I tried cutting down chaseplane and ProATC to this kind of set up 10.10.00.00 . The sounds were broken and got mico stutters. You also say place some apps on xxxxx and some on xxxx. How would you decide what goes on what? Lastly 11.11.10.10 the two red highlighted cores are now not tasked to p3d or any apps, why? You say move apps away from the right as they're doing all the work, but they're not because the AM has cut off the two main cores "0" & "2" Please enlighten me.

4.4 was made for PR. The way PR loads in 4.4 over 4.3 is like night and day.

Yes that's all correct apart from the red. They are assigned LP's 1,2,3,5,7. Are you saying 3 is bad? so 1,2,5,7 is better? I use 2 as that's only running at 25-30%

I will have a look.

LOL 🙂 Enjoyed that 🙂 Well once anyone has learned anything it's easy. How about this, go here http://www.gatwick-fsg.org.uk/affinitymask.aspx?SubMenuItem=utilties Scroll down to Affinity Mask Calculator - [Expert Mode] Fill it in, simple? Well is it "Logical and Threads"? You understand it, so do I, but I also understand why people don't. To many terminologies and things in binary or some calling them all CPU and some calling them LP/Logical/Threads.......the list goes on. I was trying to simplify to down to 4 processes 1-4 and 4 HT A-D just an attempt to get across what happening better than writing, here you go ..........01,01,01,01 and 10,10,11,10.

Sure Mike, AM is confusing and Binary being backwards does not help. The simple way to explain is adding an AM 85 is turning off the HT on a 4 core Processor for P3D, so it just uses the main cores 1-2-3-4. The HT "cores" A-B-C-D are not used. I found P3D only really used core 1-3-4. fully, they seem to all work at the same rate mirroring each other perfectly. (Core 2 was running around 25-30%) So I made every add-on I use with P3D only use Core 2 with all the HT "cores" A-B-C-D. I cannot think of a more simple way to explain it. But I think you got it anyway Mike. So P3D uses 1-2-3-4 Add-ons use A-2B-C-D. or if you want it like this "In sequence from right to left, Logical Processors (LPs): 01,23,45,67" P3D users 7-5-3-1 All add-ons use 6-54-2-0

Eureka! I've been very happy with v4.4 and was glad to leave all this AM stuff in the pass along with moving addons off & on core etc. But! After reading SteveW finding I thought I would open up task manager and watch my 8 "processors" do there thing 4 with HT ON. Like I said I was very happy with 4.4 the only time I could not get perfect smooth flight was just after takeoff and sometimes on approaches. Looking out the VC at 90 degrees at the moment in flight was not perfect. So I added in a AM=85 and loading up 4.4 watching very carefully. I saw, Logical core 0-1-2-3 working as it should be, Thread 0-1-2-3 doing nothing. Took off and did a lap of my airport. Logical core 0-2-3 were doing all the work Logical core 1 was only running at around 30%. So I upped my setting till I saw Logical core 0-2-3 peaking out, this is with FPS set to unlimited as I wanted P3D to work as hard as it could. Then I Locked FPS to my normal 26, Logical core 0-2-3 then topped out around 90%. So I went and did a full flight with AS/ASCA/ProATC/RyanairV/UTL/Chaseplane. Since I saw Logical core 1 was not being used much, I used task manager to place all the above addons on all the Threads =0-1-2-3 and Logical core 1. Result was amazing. So smooth at the most demanding times. I thought 4.4 was running well, really well, but this has placed it on another level. O well back to AM and management cores lol, it's worth it.

Very good Yes.

I just wish Steve would do a stripped down to the very basic AM setting for. 4 core no HT = AM=xxx 4 core with HT ON =AM=xxx 6 core.....you get the picture That would be nice without all the tech, graphics etc. So people can just think " I trust this guy and simple look what AM they need or not need.

I just read this topic for the first time. "P3D running but CPU not running at max speed" to Concord ZFW.......There are some serious Chinese whispers going on, in this topic. lol
