For Vista-users Gothic tweaking is easy (Vista knows how to handle the LAA-Flag)

I made a hack for Gothic 3 over at WoG:
Unzip LAA_(Version2).zip to your Gothic 3 Folder and click on LAA_all_ON.cmd.
With LAA_all_OFF.cmd everything will be changed back to original.

btw. S.T.A.L.K.E.R. is doing the same - patch 1.0003 fix list:

…
Binary files are now compiled with large address aware flag that supports up to 3GB address space (relevant for Windows VistaT users).
