Having all files downloaded, i decided to make some different choices and modifications to the combined files pack.
I finally got Combined V3 working, after removing the Realistic Overhaul and some other unneeded mods. As i made a priority to textures and improved meshes only, it will try to avoid including mods that add tree trunks or other objects to avoid conflicts with other mods.
It ran great until i entered the cold area and encountered a snow storm. There the fps dropped massively. This was caused by the snow flake mod. Again great for screenies but ridiculous for gameplay.
Realistic overhaul consists of many upscaled and sharpened default textures (probably around 50% of them), is a very big file and probably has some errors in it as well, as it was only available through a torrent file. Even if this mod is mentioned as required, the results without it are very good indeed. I think you don't really need it to get a great result.
So now i'm packing the same files, but without the snow flakes. File has shrunk to around 5.5 gig uncompressed now and that is also more manageable with installing, packing and unpacking, etc.
Just finished the compressed file that is now only 3.5 gig. This will make installing and uninstalling go a lot quicker and will also greatly improve the game loading times.
I will try Combined V4 without texture optimizer first, but with so many 4K textures in the pack it probably will hit the memory cap again quickly, lol.
Texture optimizer will make some textures look a bit less sharp, but you will only notice that when you stand very close to the objects.
As soon® as i get a more or less stable game again i will take some screenies and post the results here.
The combined saga continues.
) from Skyrim would be a cool option too.
