I edited the address space of the STALKER SoC exe files to allow up to 3.8GB of allocate-able RAM. Hopefully this should fix the "Out of Memory" errors many players encounter in a modded game.
These .EXE files are aimed towards users with a 64-Bit Operating system and >4GB of RAM. This may work with the 32-Bit 3GB switch, you may just have to find out.
Always remember to BACKUP your original .exe file.
