What I found using Google:

1) ESI - Source (32 Bit) Index registers, relative to DS,ES respectively

Data Segment (DS). Pointer to the data.
Extra Segment (ES). Pointer to extra data ('E' stands for 'Extra').

2) EAX - Accumulator (32 Bit) 
EAX,EBX,ECX,EDX - "general purpose", more or less interchangeable.

3) Code Segment (CS). Pointer to the code.
F Segment (FS). Pointer to more extra data ('F' comes after 'E').
G Segment (GS). Pointer to still more extra data ('G' comes after 'F').

4) EBP - Stack Base Pointer (32 Bit)
   ESP - Stack Pointer (32 Bit)
   EBX - Base (32 Bit)
   ECX - Counter (32 Bit)
   EDX - Data (32 Bit)
   EDI - Destination (32 Bit)
   EIP - Program counter (instruction pointer), relative to CS. Code Segment
(CS). Pointer to the code.

We have 32 bit code where we can see unhandled exception and it is the same as
EIP. So,something is wrong with counter and code segment. When you launch
Second Sight,it takes A LOT of PC resources to make memory allocation. Bela
mentioned it:"The game starts with a couple of intro videos, then comes a black
screen with a greyish loading bar at the bottom and the game freezes there.
Wineserver and secondsight.exe together are consuming 100% CPU power, so
something is happening 'under the hood', but the game never finishes
loading."It could be related with FS and GS registers,because your game,when
you launch it,freeze your PC,it takes ALL your memory resources,but I'm not
sure about it.

Any ideas?
