Optimizing textures, is it doable?

[momafcrs]

The textures in this game seem to be very poorly compressed which makes them very heavy on VRAM. For example the game is a stuttery mess on high texture quality for me on the 4 GB VRAM GPU, and the medium texture quality looks pretty bad, so I was wondering - would it be possible to extract the .ba2 files, optimize the textures with DDSopt for example, and then repackage it? It's also been a while since i used DDSopt so I'm not sure which settings would be the best to preserve quality as much as possible while reducing the size to something acceptable.

That's an interesting idea. I've got a 8GB Video Card so i'm lucky but a bit more optimization for Vram would be good.

That's surely possible. I'm sure someone is already working on that :laugh: What is really needed now is a better way of loading mods in game, without modifying original archive.

I hope this is doable.. I'm using a GTX 970 with 4 GB of VRAM and this game just fills it right up and settles at about 4.2 GB total usage.. Makes the game turn into a lagfest. With this same computer I had no problem playing FO4 with high quality textures and high-res retexture mods.

 

The difference in medium to high texture quality is massive, and using medium texture quality is just a terrible experience that makes everything in the game look like it is covered in vaseline. I honestly lose my desire to play the game when I open my pipboy and the textures on it look like total ass.

I tried compressing the textures with Fallout 4 Texture Compressor which reduced their size by 20-30%, but once loaded in game it made every single texture purple like it was missing. It was either due to my incompetence or because the tool is not compatible with F76 texture format. Hopefully someone more experience can look into this.

 

Edit: I'm currently using ReShade to somewhat improve image clarity in general, specifically just LumaSharpen effect to make things less blurry.

Yeah im on 4gb VRAM too and High Texture setting is horrible especially in towns. I hope somebody can optimize the textures.

Guys I have the same problem, I have gtx 1060 3 gb vram version and have to run game on medium quality textures even though the card has enough power to handle 60 fps on ultra details. My recommendation is to try https://www.nexusmods.com/fallout76/mods/43?tab=description it looks almost like high textures due to the sharpening filter. Anyway we have to wait for proper optimization like in F4.

I think I have found a solution and a way to compress the textures:

 

All needed information in mod description and comments. Seems like it works perfect with F76.

Use stable release (x64) from optional files.

I've done some research on this.

 

The Texture Compressor, as-is, can't be used. Not only does the catch-all compression in the tool (BC1/BC3 by default) result in bugs (black or weird looking textures), there's probably no point in compressing them as the different textures and maps already use BC1,3,4 or 5 compression - you can't get much better than that.

 

Texture size however, is another story. Many textures are over 2048px (aka 2K) which is probably too much for my humble 970 GTX. So resizing these super-large textures and saving with the original compression could help.

 

The tool doesn't do this, but I am considering working on a batch script to semi-automate the process of shrinking down 2K and larger textures to see if it helps.

 

Although I honestly don't think this will solve the issue. I don't think it's a texture compression/size problem but rather an engine problem. Remember that Fallout 76 has a HUGE render distance compared to Fallout 4 - even with the sliders all on lowest you can still see things a long way away. Or it might be an LOD issue, I'm not an expert on this so all I can do is speculate.

did you make something like this?
