Summary0004836: Early texture loading
DescriptionCurrently textures are loaded at the end of map load even though materials that create them are loaded rather early. This way we can parse materials and images at the same time in parallel.
Options/steps to move into a background thread:
0 - pass all image load errors to console as usual
1 - parse the image program
2 - load disk file content
3 - create a OpenGL texture on a secondary GL context (unless there is a context-less way to do this)
TagsNo tags attached.

I think texture loading is dominated by pushing data into OpenGL library/driver. So I'm not sure if this idea would help much given the effort.

But as usual: if you introduce some multithreading, be sure to maintain a switch which makes everything single-threaded.
There is nothing worse than unavoidable Heisenbugs in the code.

Grayman was investigating this in 2014 here:

https://svn.thedarkmod.com/svn/darkmod_src/branches/grayman_loading

I haven't found the bug tracker about it yet.

How much of this is implemented in 0005591 ?

Most likely materials parsing takes very little time, there is no sense in overlapping materials loading and image loading.
Points 2 and 3 are now done in parallel.

I think nothing is left here.
