As many of you know ET does not support HyperThreading and only uses 1 core of a multi core CPU.
However this can create issues w/ multicore cpus because XP does not properly managage which core to use.
This may not allow ET to fully use either core, or constantly swap it between the 2 cores.

XP trys to keeps things balaced by swapping processes from core to core.
Tho you can set processor affinity in XP task manager it does not save any changes.
Dual cores are represent by CPU 0 + CPU 1.
When I start ET I go to the task manager and set ET.exe to run on 2nd core (CPU 1)
For me the difference in FPS is 60 Fps using both 0+1 selected (Default) to 200+ FPS when using just CPU 1.

In my experience my AMD X2s have even more problems running affinity set to use both cores.
I remeber my AMD being wonderful for ET at 1st but slowing as I added other software to my PC over time.
When I forget to set affinty on this Intel e6600 its seems after awhile it get's processes sorted out better then my AMD did.

However there is a great app I found that lets you choose which programs run on which core.
They have a great article explaing and benchmarking this process.
This program is really a must have for dual core users playing ET and other demanding non hyperthreaded software.

Thanks.. I have to change ET to 1 core every time as well.

I downloaded it and added ET but do I have to keep it open the whole time? Or does it always run like that when I start up.

Looks like you need to run it before u play ET, Or add it to your XP startup folder.



Another nice thing to do is set certain apps not to use same core as ET.
Like xfire and explorer. Just run task manager to see which programs use noticable cpu usage.
Tho make sure you dont limit any demanding hyperthreaded software to only 1 core.

i dont have problems too.

but instead of setting the affinity you could enable the multiprocessor feature of ET -> /r_smp 1

It says r_smp is read only.

r_smp (set to 1 is not supported)

Google it you will see.

Vista is much better at multicore task managment.
However Vista isn't faster then XP. In most benchmarks it quiet a bit slower.

You can run et and taskassign by making a batch file.
Just do this by adding lines below to a Text file and save. Then rename abc.txt to abc.bat
Copy abc.bat into C:\Program Files\Wolfenstein - Enemy Territory
Then you can but a shortcut to abc.bat on your desktop
Will run both at once.
You could turn off taskassign then if u wanted to.

@ECHO OFF
start C:\Progra~1\TaskAssign\TaskAssign.exe
start C:\Progra~1\Wolfen~1\ET.exe
exit

does this work with quad core?
