I know this is an old thread, but here's the easy answer that didn't come up. WinXP (and also Vista, I believe) has a utility included called start. This utility can be used to run a program with a specified cpu affinity. the command would look like this:

start /affinity xx myprogram.exe

Use the actual name of the program you want to run, of course, and substitute xx for a hex number representing the affinity you want as follows:

01 - 1st CPU
02 - 2nd CPU
03 - 1st and 2nd CPU
04 - 3rd CPU
05 - 1st and 3rd CPU
...
etc

no /affinity parameter for the start command in XP, and also I'm hoping to find a way (program,w hatever) to set affinities just as they launch rather than manually. Thaks though sir, and nice to see you again!

I went back to Processor Lasso, which works alright. I thought it had been causing my computer to freeze, but it happened a couple times without it running. I think it's massive disk IO in my new raid device causing it to freeze (happens with utorrent running @ full network speed and sometimes when transferring files)--not sure why yet.

yup i'm still alive and doing good!

i'll do more research when i can and let you know if i find anything, i'll probably post it here one the forum because i don't seem to see you online on steam friends very often

and i do miss cs1.6, the server we had, the comunnity we had it was tons of fun, talking about it bring back so much memories

This was an interesting read:
http://www.techenclave.com/topic/392508-cpu-affinity-made-easy/

What I'm getting from it, despite them not really talking about this particularly, is that some processors/drivers/versions of xp may have affinity as an option on multicores, but others seem to be missing it.

Meanwhile, here was my batch file attempt. I was SUPER dirty, and literally copy the cmd.exe into the folder of my target program before calling the target .exe with the /C options.

echo off
copy c:\windows\system32\cmd.exe C:\Program Files\TextPad 5\
"C:\Program Files\TextPad 5\cmd.exe" /C start /affinity 1 TextPad.exe
pause

looking at the results, /affinity isn't a valid switch.

Also, sup Lethal?

goddamn the more I mess with affinity settings in Process Lasso, the more pissed off I am towards Windows. I was streaming CS (hltv.org has pro players streaming pugs now), and it was taking up ~20% of my cpu, which for just flash streaming is ridiculous (I'm on a Phenom x4 965 be). I tried switching Chrome to one core from all cores, and it dropped to around 8%. Let me repeat that: 20% across four cores vs. 8% on a single one.

In CS using all cores means constant fps drops to 50 or lower, down and up and down and up and down and up, etc., etc., even with all settings at minimum. With everything on max and restricting it to one core I'm at a constant 99fps.

Everything I've tried so far has worked as well or better when restricted to a single core.

I'm curious if Windows 7 is any better, but I had installed it, and I can't run the mouse acceleration fix (dll injection into hl.exe to get direct mouse input passed into CS) along with EAX sound.

Oddly enough, I was poking around last night in my task manager and happened to see the manual option for Affinity. Which pops a list of my cores. And checkboxes. My proc/driver/OS/MoBo combo is capable, but it doesn't seem to be a valid cmd switch.

I'm actually very interested in what the hell might make it show in some people's systems and not in others.

/Also, that's ridiculous, dude... sheeeit.

Mine has the option to set it manually from Task Manager. I was hoping for a way to have Windows memorize those choices so I wouldn't have to do it every time. It's fine for something I keep open all the time, but cs for example I do not. Process LAsso has been working out alright. It has some additional features that I'd rather not use (like changing priority when it somewhat arbitrarily decides a process is using too much cpu), but it memorizes affinity choices at least.

Yeah, that was more or less my experience as well. But that means there's a switch somewhere. Registry doesn't feel right. MsConfig doesn't feel right. CMD isn't right, apparently. What's Process LAsso written in? I have a code explorer that works pretty well at dissecting things in VB.Net and C#, so I could at least see what APIs it's calling to set affinity.

It's a fucking computer. If you can set something manually, you damn well better be able to set it automatically. I don't like mysteries inside my devil-box.

It's in c++ http://bitsum.com/prolasso_why_native.php

" We [...] used the lowest level API available for process management - the largely undocumented NT Native APIs. "

gotta love undocumented api's

HA! Good work. Probably the NTDLL.dll library then. Just based on it's being the biggest meanest Native API in NT.

Woer i am not sure if it could help but if i remember correctly cs had launch options you could set on steam to fix mouse accelleration with those commands -noforcemspd -noforcemaccel -noforcemparms

there is also other commands for which directx you want to use, set how much memory you want cs to use, disable certain options to gain fps and such it might not fix your problems but it might help who knows

This link has a lot of launch options

I remember using those commands while playing cs as launch options : -noforcemspd -noforcemaccel -noforcemparms -heapsize -noip -noipx -nojoy -dxlevel


@Nunes Like i meontioned in a previous post i'm doing well and fine, how about you

Every day's a party. At least that's the best explanation I have for the number of clowns I deal with every day.

You can make it so when you right click the .exe, you can click "run on CPU1".

And here's an open source program that seems to be able to do it also. http://www.adsciengineering.com/StartAffinity/

Yeah, that's probably a trap.
