📋 About This Mod
This tool can upgrade previous texture BA2 to newer high-performance textures BA2 (Version 3).
Starfield uses the new format BA2(version 2, and version 3)
BA2 version 1:
Fallout4, Fallout76, etc. BA2 created by Archive2.exe.
BA2 version 2:
Same compression/decompression as Version 1. used for Textures not requiring performance, non-texture datas, etc.
BA2 Version 3:
Faster decompression when texture transfering to video memory.
since the tool to create new BA2 (Ver. 2 and 3) is not yet available, I have created a tool to upgrade the previous BA2 (Ver. 1) to the new Ver. 2 and Ver. 3.
please use it as a stopgaps until Bethesda releases a new archiver or someone else creates. 🙂
BA2 Version 7,8: ( optional support)
used by Fallout 4 Next-Gen.
Possible convert:
Upgrade Ver. 1 to Ver. 2
Upgrade Ver. 1 to Ver. 3 (texture BA2 only)
Upgrade Ver. 2 to Ver. 3 (texture BA2 only)
Upgrade Ver. 1 to Ver. 7 optional support for Fallout4 Next-Gen BA2 Upgrader 1. 3. 0
Upgrade ver. 1 to Ver. 8 optional support for Fallout4 Next-Gen BA2 Upgrader 1. 3. 0
Downgrade Ver. 3 to Ver. 2 (texture BA2 only) BA2 Upgrader 1. 1. 0
How to use this tool effectively.
There are many texture mods available in Nexus, but at this time they are all BA2(Version 1) packed.
Upgrade to Version 3 that texture mod's BA2. Perfectly fits the Starfield. 🙂
not recommend to use lot of texture loose files. texture should be used in BA2 packs.
non-textures datas (swf, meshes, sound, etc.), upgrade to Version 2.
FAQ:
> Will this reduce video memory usage?
> No, it neither decreases nor increases.
>Will this improve FPS?
> Depends on the case. this would be effective in scenes where a large amount of texture loading occurs.
> Change the graphic quality?
> No changes, It neither improves nor deteriorates.
> Does this contribute to higher overall performance?
> Probably... I think Bethesda introduced a new version of BA2 because it's effective.
> maybe the area change will be faster, or the stutting will be gone.
NOTE:
only Texture BA2(Ver. 1 or Ver. 2) can be upgraded to Version 3.
Not recommend Upgrading Starfield's stock BA2(version 2). Bethesda has good reason to choose version 2.
* BA2 file size will be larger when upgrading to Version 3, because of the emphasis on decompression speed in tuning.
