LAA 4GB Memory Patches released for Doom 3, Half-Life 2, Resident Evil 5 and more

Daniel Pistelli has released LAA 4GB memory patches/mods for a number of games. As such, we’ve decided to collect most of them and share them in one post.

As Pistelli noted:

“x86 applications have 2GB of virtual memory out of 4GB (the other 2GB are reserved for the system). On x64 systems these two other GB can now be accessed by 32bit applications. In order to achieve this, a flag has to be set in the file’s internal format called LA”

According to the modder, these patches should allow for smoother gameplay, faster loading times, better fps and less frequent crashes. Naturally, owners of low-tier/mid-tier PC systems will, theoretically, see benefits from these patches. After all, high-end PC systems can simply brute force through these games.

But anyway, here are the LAA 4GB patches for Doom 3, Half-Life 2, Resident Evil 5, STALKER: Call of Pripyat, The Sims 2, Resident Evil Revelations 2, Manhunt, Payday 2, and Hitman Absolution.

Have fun!

While he is a die-hard PC gamer, his gaming roots can be found on consoles. John loved - and still does - the 16-bit consoles, and considers SNES to be one of the best consoles. Still, the PC platform won him over consoles. That was mainly due to 3DFX and its iconic dedicated 3D accelerator graphics card, Voodoo 2.
