Officially the requirements haven\'t changed.
That said, on an average poll, people seems to enjoy a better performance with this version compared to .12
If you were able to use .12 but experienced some lag, you\'d definitively try .13 to see if for you there\'s an improvement too.
NOTE: Currently .13 has memory leaks that are being solved, specially related with the new sound renderer. Just try it anyway, and if it keeps not working, await the fixes to those memleaks (that will be the ones bugging you since you\'re low in RAM) to try it again.
Recommendation: Don\'t touch sound using the setup. To try to minimize the sound impact on performance, go to options when ingame, and disable background music, effects, etc. Good luck with it.
