Game Issues With Multiprocessor/Hyperthreading Systems
If you're reading this you probably already know that Thief, Thief Gold, Thief 2, System Shock 2, as well as Grim Fandango don't like multiprocessor/hyperthreading systems.
The non-permanent way to fix this problem is to:
1. Start the game(go only as far as the menu).
2. Alt-Tab out of it.
3. Bring up the task manager(Ctrl-Alt-Del then T).
4. Click on the processes tab.
5. Find thief.exe / thief2.exe as well as thief2.icd for thief 2 / grimfandango.exe for Grim Fandango.
6. Right click on it/them and go to set affinity.
7. Uncheck one of the cpus.
8. Alt-Tab back into the game and play.
This will need to be done every time you start the game as this is not a permanent solution.
The permanent way to fix this problem(without turning off Hyperthreading) is this:
1. Download imagecfg.
2. Unzip it to Windows\system32\ as well as Windows\system32\dllcache\.
3. Make a backup copy of your exe and icd(for Thief 2 and System Shock 2) files.
4. Open notepad and enter the following for Thief/G:
imagecfg -u thief.exe
imagecfg -a 0x1 thief.exe
pause
For Thief 2 it's:
imagecfg -u thief2.exe
imagecfg -u thief2.icd
imagecfg -a 0x1 thief2.exe
imagecfg -a 0x1 thief2.icd
pause
For System Shock 2 it's:
imagecfg -u shock2.exe
imagecfg -u shock2.icd
imagecfg -a 0x1 shock2.exe
imagecfg -a 0x1 shock2.icd
pause
For Grim Fandango it's:
imagecfg -u GRIMFANDANGO.EXE
imagecfg -a 0x1 GRIMFANDANGO.EXE
pause
5. Save the file in the game directory as "processor.bat" including the quotes.
6. Double click the file processor.bat (must be in the game directory). You will see something similar to the following:
D:\Games\Thief2>imagecfg -u thief2.exe
thief2.exe contains contains no configuration information
thief2.exe contains a Subsystem Version of 4.0
