Guild Wars 2

I don’t remember if I set it or it’s linked with it by ANet and -repair doesn’t change my GW2.exe, so someone else check if the Large Address Aware bit is set. If it’s not, might give 4.0GHz+ Sandy’s and Ivy’s a boost in LA and WvW.

Its already LAA enabled, no worries.

Well tested on mine original was set for LAA and it’s already set to LAA as well.

Yea, figured as much. Had a little hope

“LAA” is the reason why changing from a 32bit OS to a 64Bit will solve those pesky out of memory errors. GW2 uses around 2GB memory on longer WvW sessions, which unfortunately is exact the maximum amount a 32bit OS will allow per process. With LAA on 64bit this is lifted, therefor no crash.

The only problem i have is: WHY the heck is the application crashing? There is a “out of memory” error return code for every memory allocation function u call. If your memory malloc fails, do a D3D texture memory flush, this normally frees up the managed system memory, which will allow to prevent this kind of error.

This is lazy beginners coding and memory handling only PC company’s can get away with. If u run out of memory on a PC and have no fallback or error handling in place, your memory management system simply sucks!

On a 64-bit OS, 32-bit programs with LAA are still limited to a maximum of 4GB of mem usage.

For unlimited maximum mem usage, the executable needs to be 64-bit.

the LAA flag is ultimately ignored in 32bit operating systems by default, however you can get it to have “some” effect by enabling whats called the “3GB flag”

If you google “3GB Flag your operating system 32bit” so for example “3GB Flag Windows XP 32bit” it will tell you how to enable it.

Nothing to lose in trying :P

Here is some more information on it: http://www.zhihua-lai.com/acm/large-address-aware/

“On a 64-bit OS, 32-bit programs with LAA are still limited to a maximum of 4GB of mem usage.”

While true, most games only use 1.5-3GB available memory. So fixing the 2GB process limit is what helps those memory hungry games. So while a 64bit executable would be optimal, a 32bit + LAA is a working compromise.

@Refraction.1892, thx i tried this once, but did forget about this! Now i already have switched from a 32 to 64bit OS, but others may try this first, since u can just “upgrade” from a 32 to 64bit OS, which means lots of reinstalls.

Bottom line is, if you have 4GB of RAM, there’s no valid reason for not running a 64-bit OS, especially since when you buy any version of windows, your license entitles you to both the 32-bit and 64-bit versions of the OS.

Not if it’s Windows XP :P

Just noticed the OP topic: “LAA bit (might increase FPS on high-end rigs)”

Why does everyone assume more available memory has anything to-do with FPS? At best it reduces loading times and prevents “hick-ups” from page swapping on HDD and in GW2 case prevents this out of memory crash.

“Bottom line is, if you have 4GB of RAM, there’s no valid reason for not running a 64-bit OS,”

I know a very good reason: my tv-card (PVR-150) does not work with a 64-bit windows version with 4GB or more memory installed

@Fu Ling U.6918, there you go!
