Dual Core - selecting startup Affinity

[Prophet]

So having a dual core, and with Lockon I prefer to have Lockon run on 1 CPU and everything else run on the other.

 

Now we know about procaff for Lockon string, but I have been wondering how to make the other application startup with the other.

 

If you open msconfig, and go to startup you will see the registry key that is used for the startup. It is usually;

 

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run

 

In there is listed most of your startups. You then select the key, right click and select modify.

 

I run D:\WINDOWS\procaff.exe /run 2 D:\Program Files\Lock On\lockon.exe for Lockon.

 

So I added D:\WINDOWS\procaff.exe /run 1 to the beginning of everything in the registry section above.

 

Then if you go to startup folder in the start menu, you usually have a few more things, just add D:\WINDOWS\procaff.exe /run 1 to there Target field like you do for the Lockon shortcut.

 

Currently researching on how to make explorer (the shell) startup on the core you want.

[Prophet]

There are more startup keys under;

 

HKEY_LOCAL_USER\Software\microsoft\windows\currentversion\run

[Prophet]

Ok so to get explorer to start up under the CPU you want

 

in regedit, go to;

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\System

 

In there add a new string value, name it Shell. Then right click and choose modify. Add;

 

D:\WINDOWS\procaff.exe /run 1 explorer.exe

 

of course choose the CPU you want for procaff 1 or 2.

So far its a decent increase, about what you would expect if you killed all your other apps.

Very nice thread, Prophet! Thx a lot!:thumbup:

[Pilotasso]

we would need this as a sticky.

Nice work mate... I was thinking of how to make all windows applications and servcies start up on only 1 core but never got to it :D

 

Much appreciated for this thread... I'll try it later tonight on my machine.

[Prophet]

Its not services though, I am still trying to figure that out.

[Kuky]

ah... well please let us/me know when and if you figure that one out ;) I'd very much like to have services on single core also... if possible at all :D

[Prophet]

Well its hard to tell. I am unable to even see what processor the services run on.

[Kuky]

On my one, when I look into the Task Manager, all processes that were started by the OS are marked as running on both cores, but the box that is to check/uncheck CPU is greyed out.

[Prophet]

I can only see the affinity of processes started by the user. Everything else gives me an error access denied.

 

But all processes under the user are on core 1, and only Lockon is assigned to core 2.

 

I am sure there is some way of to assign affinity to the services, but I am not that much of a computer guru.

[G3]

yes a good thread and perfect timing, i have done the manual affinity thing after things are running, some things let you and some don't.

and i see prophet is onto a way to go in a change reg entries.

so its a one off permanent fix?

 

=Prophet= So far its a decent increase, about what you would expect if you killed all your other apps.

thats sounding good, when you think about it there's a fair bit going on other than the lockon game itself.

 

would be nice to have a simple option to somehow select a "gaming mode", and then only the game would be on one core, all the other background stuff on the other core.

 

1, is there a way to specify an app to get sole access to use one core exclusively, as in force it to reserve the full core for the game?

 

2, is it best to set lockon to core 2?

[Prophet]

1. I dont know. There has to be something I would think but I havent found nothing yet.

 

2. I use core 2, because when I was overclocking, it would handle higher overclocks better (Prime95). So even though I have it clocked to where both cores are stable, I just figure why chance it.

Yeah you're right, my previous post is an unintentional "lie" :smartass: I can't access any SYSTEM run process either.

This also works in IL-2FB. When I assign the affinity in config.ini:

 

[rts]

ProcessAffinityMask=2

 

I get a major increase in FPS.

[Prophet]

Nice.

 

Yeah since its a windows mod, it should show improvement for any game that doesnt use dual-core.

if thats an ingame setting, the question is does lockon have a similar setting anywhere???

 

prophet, i am unsure of your meaning "windows mod", is this file found ingame or is it in windows?

 

cheers, ggg

[Prophet]

What file do you speak of? The config.ini? I am sure thats an IL2 file.

 

But all the reg edits.... thats windows.

[G3]

try to clear the mud:smilewink:

 

in il2's config it has:

 

[rts]

ProcessAffinityMask=2

 

i was hoping there might be a similar entry we could add to lockon's config...

[Prophet]

Not that I know of. And since I am using Procaff to sort everything else out, since windows wont for me, its no big deal.

is this core necessary for people with duo core 2? Because it seems to run pretty nice on a duo core 2 since i believe the other core is being used for trackir and other joystick resources.

Can anyone confirm whether this brings a performance advantage?

This will not increase performance... but can reduce/eliminate stuters.
