Copy and paste this into a .bat file and watch the fps increasing magic unfold!
Edit: FAIL/oops
START "Morrowind" /high /affinity 6 "%MORROWINDFOLDERHERE%\Morrowind.exe"

Note:
To use with fps optimiser just open the program then run the .bat file, fps optimiser detects when Morrowind is launched, so it will work as normal.
I also reccomend (If you have Vista or 7) to set dwm.exe or any other cpu using .exe (except explorer. Beleive me you don't want to know what that does...) affinity to your last cpu.

I suppose I do not need it with a 6-core?

Neat. Couldn't you also just add this to the end of a .lnk pointed at MW.exe?

What's wrong with stopping Explorer, by the way? You know you can just restart it by opening taskman (CTRL + SHIFT + ESC) and then starting it as a new task (click new task, enter "Explorer", hit enter, you're done).

It is probably possible with a hexacore just as well, and just because you have six cores doesn't mean Morrowind will use them all, duh. So if you want a decent framerate, even with a hexacore, you should do that.

I have a .bat to do that...
It will work on 6 core, in fact any amount of cores 3 or above.
What the .bat does is uses core 2 and 3, these cores will not have as much load as core 1, it definitely gives me better fps.

Any method on how to create the .bat file coz in win7 adding .bat at end doesnt work it remains a .txt file.
Could u explain it with a little more detail about what to do with dwn.exe and other exe`s?

EDIT: Got it to start but it doesnt work for me i get the same fps for dual core processor i have a Intel Core™ 2 CPu 2.0Ghz each

Next step decyphering.....

Doesnt do anything for me either, Q6600 @ 3.2 and i still get around 25 fps, in my .ini the FPS is limited to 60, same as in MGE

It gave me about 5 more fps, probably because I told everything using cpu to go onto the 4th thread and maybe the fact that I have a Hyperthreaded i5 (dual core)
Anyhow.
To make a .bat file on Windows 7 (In fact, any windows NT version 2000 or later)
you go into a folder (any folder), press alt and a bar will appear mysteriously near the top of the screen/window.
In this bar click tools, then folder options.
When folder options appears click the view tab at the top of the window and deselect hide extensions for known file types.
You can now make a .bat file by writing the commands of the .bat in notepad and:
1. saving as a .bat in "All files"
2. saving as a .txt then renaming to a .bat

I hope I have helped some people.
This works for me and if necessary I will give proof that it increases fps.

You could, but it wouldn't quite point to MW.exe anymore (those aren't Morrowind command arguments).

Bad practice. Explorer likes to try and restart itself and some apps like to depend on it (which is also arguably bad practice).

Exact increase will vary tremendously over a variety of factors. in particular, what's already running on your system and where. If you have apps that the OS has shunted to core 2/3/4, you won't get much/any increase. Same if core 1 isn't used much (although that's less likely). Which cores you should send it to is very system- and run-specific.

Hyperthreading is extremely unlikely to give any statistically significant increase, but it's completely plausible cores will (even pushing to the second in a dual core could, if that core is less used). This is also not MGE (XE) specific, it will apply to the vanilla game as well and probably net some increase there.

I'm having trouble getting this to work. I pasted START "Morrowind" /high /affinity 6 "C:\Program Files\Bethesda Softworks\Morrowind\Morrowind.exe" into a txt file and changed it to a .bat and when i run the batch file nothing happens. I'm using xp 32bit.

Oh, duh, about the command arguments. Doh

I used to have to close explorer to play a lot of games at decent FPS way back when my computer svcked. Never seemed to be a problem.

For those asking about hexcore, or even quad, the affinity argument uses a bitmask in hexadecimal form so far as I can tell. The full table is something like:

core 0 = 01
core 1 = 02
core 2 = 04
core 3 = 08
core 4 = 10
core 5 = 20

Sum the affinities you want set (6 for 2&3). Note that these are hex, so 2 and 3 is B, not 12. Unfortunately, proper docs on the command neglect this argument, so this is primarily hearsay.

To explain it in simpler terms
it basically works like this:
Look at core list above
core 1 (2)
+
core 2 (4)
=
6
So
/affinity 6

This is not working for me too.

Are you sure you have Morrowind installed in that location?

It doesn't work on XP, only Vista or 7.

Neither work for me. I think there's a program ... ProcessLasso, or something similar to handle this in Windows XP.

When I try this, I get an MGE GUI.exe is not configured message, or if I try to run the launcher instead of the exe, I get a message stating that the launcher can't find the morrowind.exe

ProcessLasso will work on Vista too. I tried it for a while. Seemed to make things run a bit more smooth during launch, but otherwise didnt do much else; unless it is what did something to effect internet explorer.(seemed like load times increased for that after I installed it but I dont see any obvious evidence something changed)

Though I dont get any fps increase(probably coz i dont run simultaneous prgrams or much files running) but as far as your problem is concerned i also experienced it
To fix it just copy that .bat file to your morrowind root directory and try again it should work.
