CPU Affinity Shortcut for a Program - Create in Windows

[wykydtronik]

Has anyone got this working with OBS Studio 64 bit? I got mine to work, I wanted to contribute to this thread.

This forum is frustrating... I can't post to this thread without Cloudflare blocking it! I get

"Oops! We ran into some problems.

It's blocking he command that OP is talking about. Below is a screenshot of how I got OBS running with this command.

I 've never seen it do that before, are you trying to attach something?

No, I think it has to do with the lines where quotes and .exe is. In the screenshot the second line seems to trigger the Cloudflare error.

One thing to note: I changed my hexadecimal to F to utilize 4 CPU's. OBS didn't like being limited to 2.

Hi Brink,
Excellent post and valuable information. However, I currently have AMD Ryzen 3700x CPU 8 cores, but in task manager I see 16 cores, see snip below. Could you please let me know which of them I have to choose in order to allocate my last core (8)? Do I have to take into consideration 2 cores (I assume one of them is virtual core?). Or do I just allocate one of them? I am running a game which is designed to run on just one core therefore I wanted to allocate my last core which is used the least by my PC and would not interfere with other processes. I tried to allocate myself and noticed that the 14th is the 8th core but then I am left with the 15th core as per task manager. So what do I do with this - should I allocate it together with the 14th core assuming that 2x cores per task manager = 1 real core?

Your input would be much appreciated.

Hello @SweetPapaya, and welcome to Eight Forums.

AMD has multithreading like Intel's Hyper Threading.

It doubles your physical 8 cores to effectively be 16 (0 to 15) instead.

You could use core 15 for the last one.

Thank you, Brink

What about core 14 then? Do they not work in a pair?

They will behave as single cores, but you could select more than one if wanted.

Hi, i am having a few custom Programs that i use with Microsoft Access Runtime 32bit in Windows 10 64 bit and i want them to only use CPU 0.
Some reports in my programs give me in random cases the error message "System Resource Exceeded" and the only solution that works is if manually set the affinity to CPU 0. I am confused on how to make the shortcut to set the affinity from the start at CPU0.
Ms Access is installed in location below:
C:\Program Files (x86)\Microsoft Office\OFFICE11\MSACCESS.EXE
And my Programs are in C:\Apps\.. For example:
C:\Apps\Orders.mde or C:\Apps\Support.mde

i tried the following but with no success!!
C:\Windows\System32\cmd.exe /c start "MSACCESS.EXE" /affinity 1 "C:\Apps\Orders.mde"
C:\Windows\System32\cmd.exe /c start "Orders.mde" /affinity 1 "C:\Apps\Orders.mde"
C:\Windows\System32\cmd.exe /c start "C:\Program Files (x86)\Microsoft Office\OFFICE11" /affinity 1 "C:\Apps\Orders.mde"
C:\Windows\System32\cmd.exe /c start "OFFICE11" /affinity 1 "C:\Apps\Orders.mde"
C:\Windows\System32\cmd.exe /c start "Microsoft Office Access" /affinity 1 "C:\Apps\Orders.mde"
C:\Windows\System32\cmd.exe /c start "Microsoft Office Access (32 bit)" /affinity 1 "C:\Apps\Orders.mde"

Any ideas?

Hello Fuzzee, and welcome to Eight Forums.

You should be able to use this below for the shortcut.

You would have wanted to use the full path of the executable file in the part in red below.

cmd.exe /c start "Microsoft Access" /affinity 1 "C:\Program Files (x86)\Microsoft Office\OFFICE11\MSACCESS.EXE" "C:\Apps\Orders.mde"

Thanks Brink it works fine!

Many thanks to OP, this worked great for setting cores on my 3900x, 12c/24T sitting at 10-30% usage under load and running neither program effectively at all.
I was trying to stream on twitch and I was getting stuttering, lag and dropped frames in game and in OBS.
For apex legends I set the affinity in the launcher app-Orgine. Which let all programs it started run with inherited settings, especially helpful since apex didn't allow for easy setting of affinity because of the anti cheat blocked the change.

Using: C:\Windows\System32\cmd.exe /c start "Orgin.exe" /affinity FFF "C:\Program Files (x86)\Origin\Origin.exe"
This set the game to just use the first and fastest CCD0 leaving the slightly slower CCD1 for OBS

Setting up OBS I was greeted with "failed to find locale/en-US.ini" same as wykydtronik above

Using:C:\Windows\System32\cmd.exe /c start "OBS Studio (64bit).Ink" /affinity FFF000 "C:\Program Files\obs-studio\bin\64bit\obs64.exe"


I fixed it by just opening up the shortcut and changing where it started in from C:\Windows\system32 to "C:\Program Files\obs-studio\bin\64bit"
Hopes this helps someone!

The 3900x is a beast I basically dedicated a 3600x to each program. I'm able to run apex legends at 1080p 144hz buttery smooth and run OBS medium 1080p at 6000Kbs with no lag or dropped frames

I'm glad it could help @Dracoflame, and welcome to Eight Forums.
