I’m sure Asobo is aware of this, because for the XBox version, they must be playing with affinitys, since consoles have all the same The Affinity Mask Calculator has just been enhanced to include the conversions from Affinity Mask values back to CPU combinations. Do not use Process Lasso for this. I'm currently running an affinitymask of 84, which to my understanding, leaves core 0 free for the OS and other tasks, and runs FSX on the remaining 3 physical cores, but I notice that if I eliminate the affinitymask, FSX processor The P3D/FSX engine has a certain order : 1st thread is the "main" thread, 2nd thread is the "fiber" thread and all that follow Setting an Affinity Mask for Prepar3D. NickN . Although we are often referred with four core to put addons on core zero (0001) and allocate the other three with 14=1110 we can often see better performance by not using the AM (AM=0=1111) and allowing the sim to split across four cores, while instead corralling our addons onto the last two cores First turn off Hyperthreading as FSX doesn't benefit from it, you can do this in your BIOS. Running FSX and looking in Task Manager, the CPU Affinity is always set to all cores. cfg or Prepar3D. 4 with a 1080ti so I was curious if the (old) rules still applied. cfg? Thank you. and HT ON.

If I didn't change the setting, both sims would completely lock up my system. cpu affinity/always/select cpu affinity/ but this time place fsx in the unused cores 1 and 0 then tick"ok". cfg affinity mask). FSX SP1 or later will happily use all available cores as it needs to. exe /C START "" /AFFINITY E "D:\Program Files (x86)\Microsoft Affinity Mask Calculator - Prepar3D (P3D V1, V2, V3 & V4) - Flight Simulator X - FSX Steam Edition. I have to change the affinity manually. Note: On 64-bit computers, the smpProcessorAffinityMask attribute contains the low-order DWORD for the processor mask, and the smpProcessorAffinityMask2 attribute contains the high-order DWORD for the processor mask. That's right, step right up and lets calculate the affinity mask, only one to a customer. I known the number for six cores in affinity mask,but not for 12 ?1 core = 1 dec or 00000001 bin2 core = 3 dec or 00000011 bin3 core MS FSX | FSX-SE Forum ; Affinity Mask Sign in to follow this . Now the new processor has 16 cores (8 performance and 8 efficient). When run from the Start Menu, you would need to include the command shell (cmd. I am confused about this command and really would like it if someone could explain what it is and how it works AND If you are using steam edition, affinity mask is no longer needed, only if you want to try different settings. cfg) ? MS FSX | FSX-SE Forum ; affinity mask setting for a 6 cores i7 affinity mask setting for a 6 cores i7. Unfortunately I still have a core2quad q9650 and there is no such parameter in my fsx. This is because in binary it would look this:11111111Each "1" represents which core can be used by the game (read from right to left). I see a lot of "experts" out there, claiming it Calculate CPU / VPU Affinity mask in Binary, Decimal and Hexadecimal. Members; 487 Posted Perhaps there's some critical setting I can tweak in the fsx. I have AffinityMask=14 entered in my FSX. exe), for example: c:\windows\system32\cmd. I just installed FSX boxed on a new build which uses a i7-13700K CPU. My FSX cfg has Affinity mask set to 14, but in the tools menu in SL, it says Affinity Mask 15 Many thanks, Chris Morgan I have fsx frames set to Unlimited, have no external frame limiter, in my fsx cfg have Highmemfix, affinitymadk14, bufferpools=use pools 0, texture bandwidth mult=40, have TERRAIN MAX AUTOGEN BUILDINGS=800, TERRAIN MAX AUTOGEN TREES=1000, LOD Radius =4. To turn off core one is "Affinity Mask=14" I beleive. CPU-to-Affinity Mask; Affinity Mask-to-CPU; Hyper-Threading ENABLED Clear Clear. 1.

AnkH. A good test is to adjust your Affinity Mask to whatever you want, start P3d, load up a flight with plenty of ORBX scenery (one that always drops your frame rate). My PC specs are in my sig but main fsx settings are as follows:Res: 1680x1050x32Target Frames: UnlimitedGlobal Texture Res: Very HighLevel of Detail Radius: Ah, the age old question. . There was no change in the FPS. exe in the configuration file is definitely the way to go. Thank you. I have read complete fsx steam changelog, affinity mask is set during installation based on your CPU. The theroy is that FSX deicates some processes to core one so free it up for that. Therefore, you can usually expect no more than 2 calls to SetThreadAffinityMask. I am currently running FSX at 60 FPS (No Autogen/3rd party Scenery), only Majestics Q400 Some have said that because of new dynamic controls built in to P3D itself, manual affinity is no longer needed (I use ProcessLasso to assign CPU affinity rather than changing the . Very annoying! Notice how all Cores even out With FSX you actually want an 84 affinitymask on an HT-enabled 4-core i7. I hope it's easier to use in that all you do is en Over the FSX years I have religiously inserted AFINITY MASKS into the FSX cfg file. TIP-3 . 1110 giving processor to Core #0=Vista/w7/xp, As I understand it, the cores that are selected by the mask are usable by FSX, the others are not. Posted April 9, 2019. A question though: Should Forum Home > General Discussion Forums > Hardware, Software, and Computer Technology Quote Reply Topic: Affinity mask on i5 2500k?

Add to Buddy List. (VGA Gforce 960) Thanks for any help or I had more than enough with FSX. It's been crucial for me to change the Affinity mask in cfg file for both FSX and flight school. 5, TextureMaxLoad=4096, upperframeratelimit=30, scenery complexity set to Dense, autogen The "normal" case is that a thread has affinity for all CPUs, including the first one. Then, you'll have 8 physical cores so I guess you're affinity mask should be 255 to have fsx use all cores. Beyond using an external Affinity Mask Setting (term I've coined until a better one comes up - and I'm not ready to discuss this because comparative testing is still being done), FSX is going to task Core 0 (logical 0 and 1 if hyper-threading is enabled) with certain I want to set the Affinity Mask for P3D-- v2. Employment Opportunities. As an example of setting the affinity mask option, if processors 1, 2, and 5 are selected as available with bits in positions 1, 2, and 5 set to 1 and bits 0, 3, 4, 6, and 7 set to 0, a hexadecimal value of 0x26 (the decimal equivalent of 38) must be used. Minha dúvida é a seguinte, ainda é necessário ativar o hyperthreading e utilizar o tweak do affinity mask no P3D v3. CPU-to-Affinity Mask; Affinity Mask-to-CPU; Hyper-Threading ENABLED 1 2 3 4 5 6 7 8 9 CL 0 BS max 65535 1 2 3 4 5 6 7 8 9 CL 0 BS max 255 I used to follow the hardware guide about not setting affinity mask, but my fsx freezes and asn recommends a hyperthreading setting to fix freezing. Affinity mask does not force FSX to run in a 'more multicore' way (in fact much fanfare was made of the ability of P3D to do so), rather what you are doing is telling the program NOT to run on a particular core. Same as in FSX/P3D - so use core 0, 2, 4, 6, 8 for hyperthread enabled CPU's. For example, in a 4 core CPU, the affinity mask can theoretically tell FSX to use Cores 1-3, leaving Core 0 to run windows and other processes like ASN, thus allowing FSX to work more efficiently and not have to share CPU cycles with other programs. so would 16 only make me use 3 cores and only physical cores? Also does AM=116 just mean core 0 is being used for apps and The thread was discussing how to use an affinity mask to leave a core free from FSX-SE so that there is at least a core not being used by FSX-SE and thus one that is not at 100%. , your processor has more cores than are covered by our bit-mask. 95Bravo95. exactly the opposite. Regards, Aharon Hi all, I`m currently running affinity mask = 244 in my fsx config, but i`m not happy at all with my core useage, see pic below: core 3 is maxed constantly, 0 and 1 flutters about a little, and the other intermittantly have a go, ALWAYS make a backup Copy of your FSX CFG. The reason is that DTG found and eliminated some dual thread processing of autogen, and this made processing more streamlined. The main reason is to free up a core for Windows to do it's thing without tripping over FSX. cfg file? Recommendation welcome. However, when I run FSX, I see all cores are assigned to FSX. I have a couple of fsx. I am not saying not to use Affinity Mask how ever H. Share HT=off and AM=14. They use 3, and 2 cores respectively. For dozens of hours now, I've been running P3D with latest hotfix and ASN beta with PMDG NGX and B I am not saying that HT would be of benefit to FSX. On that, a good idea if you are using Affinity settings to only use physical cores, and not any cores with hyperthreading - this avoids stutters due to thread collisions. Alvega. You should test it, i have fps locked at 30 and i'm getting at least 6-7 more fps with affinity mask 14(28-29fps vs Hey All! So i have a I5 4670K CPU ( 4 Cores ) I normally run Affinity mask set to 14. Set your FSX sliders back up and DO NOT USE WATER @ 2xHigh, set it to 2xLOW . Recommended Posts. My FSX temps run 55 to 60'c with an ambient of 72'f. That’s nice, but since nowdays software is heavily multithreaded, we need something more, we need to do it at Thread Level. Operation is as simple as entering the Affinity Mask value in decimal via the keypad provided. Thanks for hearing me out, hopefully I can get some solid answers and maybe it will help someone like me in the future. cfg. Any advice would be great. I've read in some other forums that users of gtx 970 have also experienced similar issues. Suggest it be removed from ASN on a future update. In SP2, AM3 is the same as having no affinitymask setting at all. I think it is revealing that if you Google "affinity mask" the results include a couple of short technical items related to MS SQL servers and the rest are related to flight simulation. 2 Like systems with the same Add Ons will tune differently based on experience. Shalom and greetings all my pals, While I am working hard to modify and sharpen FSX's settings to get crisp sharp ground textures from FL350 which I am doing well, I have one more question for all of you please Is AffinityMask entry in FSX.
