Hello,

I saw somewhere that we could decompress bsa to increase performance. But I also saw that it was not advisable to use bsa files larger than 2GB. Now my file is 2.02 GB textures, what should I do?

What is the exact filesize of your textures bsa in bytes? (from properties)

Basically are you sure it isn't 1.92 gb?

Edit: Apparently, I was confusing Virtual Storage and disk storage. The conversion we're talking about (disk storage) is a 1000:1 MB:GB ratio. Either way, check GB in the file properties, or if you're on Windows 7, when you select it, the GB size is shown in the bottom of the explorer window.

If you right-click on the file to look at the properties, you'll see the size: 1.92 GB (2,069,465,123 bytes)


Happy gaming!

Has it ever been "proven" that re-packing the textures bsa uncompressed improves performance? I did it but I was never able to notice a difference.

Your uncompressed textures should be 2,069,377,573 bytes.

I've never had any problem running the textures uncompressed. And as said, the file is 1.92 gibibytes uncompressed. Running the files uncompressed helps with load times. In my case, with FCOM installed it saves around 15-20 seconds on initial load.

Speaking of, the proper use of prefixes when dealing with multiples of 1024 involves -bi-, according to the International Electrotechnical Commision when dealing with binary storage. For example: kibibyte (KiB), mebibyte (MiB), gibibyte (GiB), or tebibyte (TiB).

The performance increase isn't about a boost in FPS, although a really strapped system may see an increase of 1 or 2, it's to reduced loading time of the data files, which ultimately reduces stuttering/lag.

Edit: FYI, there are two sizes that may be seen because there is a two-file difference depending on whether you used the Oblivion 1.2.0416 patch and the SI version.
