I also have issues when playing SWTOR while other 32 bits applications are consuming a lot of RAM.
In my case, I use Opera for mails, IRC and web and it uses around 1 GB of RAM, if I launch SWTOR, this one is constantly swapping so I suppose it's related to 32 bits processes virtual memory on 64 bits system.
The only things you could do :
- use 64 bits software
- close program that use a lot of RAM
In my case, I'm preferring 64 bits versions of applications but there are a few little of them
I don't understand why it's so hard to compile a game in 64 bits !
I'm a C++ developer and all my applications are compiling and working in 64 bits. I also have ported Ryzom, a science-fantasy MMORPG, to Win64 and it works like a charm.
