Good AA solution for TLJ on nvidia cards has been a sort of Holy Grail for the past couple of years. And it is nowhere to be seen, which means that getting AA to work on current nvidia cards and windows version is very difficult, if not impossible.
I would gladly test that modified DX_module.dll file, but from what I understand it disappeared along with the site.
Releasing 2CD/DVD version also broke some previously working community fixes, so that's another issue.
I am still counting on Funcom releasing remastered TLJ for iOS on Android and/or PC. I'm afraid that's the only option of getting decently running TLJ on modern machines.
EDIT: I read the thread and from what I understood, the DX_module.dll file was not modified, but it was from a different version of the game. People were experimenting by trial and error, trying different versions of dll and exe (patched, unpatched, from the demo) file in various combinations and one of these combinations worked. But that was almost 10 years ago, so like I said, there is no guarantee that the same fixes would work today. I am almost certain nvidia made changes to their drivers which made AA in TLJ an impossibility.
EDIT2: There is a solution but only for ATI cards: http://steamcommunit...80278002576177/
Perhaps if enough people badgered nvidia about it, they would fix it. Start creating those support tickets http://nvidia.custhelp.com/
