Is Rebellion "Large address aware"? If not, why?
It is not. We did look into this, but determined it would make the game too unstable during our investigation.
If I manually enable LAA, will it improve performance in late games?
For me personally the cause of lag is my CPU, not RAM. LAA would be of most use in being able to load things like more factions, ships etc. into memory (and thus helps most with large mods), however it may not help as much as you'll hope with lag from having to do movement and firing calculation for large numbers of ships and strikecraft. If it is a ram issue reducing your graphics settings from say highest ship details etc. to lower ones should help. If you don't get that improvement I don't think RAM is what is holding you back.
Its ram "speed", and CPU "speed" that are the bottlenecks. You can have 6 gigs of ram, but if its ddr 3 instead of ddr 5, of course sins will run a little slower. Same with cpu clock speeds. 4 gig cpu is better than a 3.5 gig. However the difference in sins performance is only a slight improvement.
DDR4 doesn't debut until next year with Intel's Haswell processors, so how can we get DDR5 memory?
Thats GDDR, and since hes saying 6GB hes talking about system and not video memory most likely, of which there is no DDR4+, just DDR3. Regardless, faster is better than more when it comes to Sins. So enabling LAA would only help if the game was crashing because it was hitting the 2GB limit. And while were on topic, single core game + 2GB memory limit + year 2012 = grrrrr
anyhow, the only way setting the LAA flag would help is if you have more than 4gb of ram on your system. The only way having more than 4gb of ram on your system is useful is if you have 64 bit, so all in all, you would want to have a 64 bit OS and more than 4gb of ram.
Then, it is only a small improvement, but it is helpful.
Some of us gets crashes unless we manually flag the game for LAA. A game may last 5 min or over an hour, but the crashes are inevitable. As soon as a player flags his game for LAA, he never crashes again. Not sure what's going on with the memory usage there, but apparently 2gb isn't enough on some setups.
If it helps, we all run Win7 64-bit, and have at least 8gb ram installed.
Of course me and my friends with these problems can just keep applying the LAA flag ourselves after each patch. It would be nice to have it flagged from the start, though. 
That poor horse.
I wish that dead horse becomes a ZOMBIE HORSE and beat you sick bastards back!
With the 2014 version of the game [1.82], running out of app/user address space is far from the main cause of crashes [using the stock/non-modded game]. I've loaded 10-way FFA map recording (which really just plays the game anew if you know its internals work) and the game still had plenty of address space left after 45 mins: about 700MB free and the largest continous block of that was over 300MB. And then the game crashed as it often does unfortunately during playback. I've used VMmap (http://technet.microsoft.com/en-us/sysinternals/dd535533.aspx) for this simple analysis and so can you, if you don't believe me. So the devs need to fix the crashing bugs, but those are not caused by running out of memory (most of the time).
As for enabling LAA, that's no magic pixie dust. See the more recent thread: https://forums.sinsofasolarempire.com/454494/page/2#3474077
The reason for the necro is that there was another thread ("4GB") on the same topic recently, which I linked to. Also this thread contains the semi-official response from the devs, unlike the other one.
It doesn't help that this forum isn't moderated much, so the exact same topic is discussed in N threads with no pointers to each other [prior to my necro].
I know most forums encourage using older threads (provided they are still valid) instead of starting new ones, but here necroing is looked down on even if the thread is still valid...it's just one of those quirks of the Sins community....
Here it's better to start a new thread and beat a dead horse than dig up a dead horse from years ago...
