4gb Ram Patcher

Preliminary Oblivion Ram Optimization readme 0. 1c by R. J. R. This isn't a in depth guide (yet anyways). Just some info on what seemed to work for me that you may find helpful (even if sorely lacking in some details). All credit for the awesome 4gb patch program goes to Daniel Pistelli.  Big thank you for Daniel's permission to host here on nexusmods.com.

Oblivion is poorly optimized for modern systems. By default it is maxed out at a theoretical ram limit of 2gb (although it'll crash before reaching this limit, typically 1. 6 to 1. 8 gb max in practice). Using a nifty little utility you can raise the theoretical ram limit to 4gb although it'll never likely get close to utilizing this much in practice. Oblivion is hard coded for 32bit so larger than 4gb cannot be allocated per process (although seperate processes might allow greater than 4gb system ram to be to overall benefit). Some people may get a performance improvement. For others this patch would be useless. It all depends on your hardware setup, operating system (i.e. 32 bit or 64 bit), how many and which mods you are running, and finally what tweaks and extra utilities you use to help force oblivion to use some of this higher theoretical 4gb limit.

Bare minimum requirement to even consider using this patch is 4gb plus ram. Any less ram and this patch is pointless no matter how you look at it!!!  The first 4gb of ram on your computer is what Oblivion will want to use due to limitations in it's 32 bit code, so even with the 4gb patch applied you'll still want to optimize this memory by closing any unneeded processes in the windows task manager or automating this with a game optimizer which does this automatically (such as Razer Game Booster for Win XP, but which optimizer will work best for you will vary depending on your setup). Even then your operating system makes a big difference.

For Windows Systems with Less than 4gb ram This patcher will do you no good obviously. Best bet on optimizing ram is shutting down all unneeded processes in the taskbar or using an optimizer such a Razer Game Booster which shuts down all unneeded processes while running the game automatically.

For 64 bit Windows Operating Systems (e.g. Windows 7 or 8 64 bit) with 4gb+ ram

1st.) Use the 4gb utility downloaded here to apply the LAA patch to all .exe and .dll related to oblivion. You just open the program and select which files to patch and click open on each. The program makes backups of the original files automatically (with a ". Backup" file type you simply remove to overwrite the patched file if need be). This allows them to use greater than the default theoretically limit of 2gb. 4gb per process patched tops (less in practice). To take the fullest advantage of this patch requires 4gb of FREE ram after whatever windows and any other programs are running gobble up.
