While some gains can be had from further optimization I doubt we can significantly improve the loading times. In the case you have grass enabled and texture quality set to Ultra there's a lot of stuff to load especially in the case of newer tracks that have a lot of foliage variation and use multiple terrain blend maps. If you're running low on memory will cause a further slowdown to loading due to swapping (having your page files on SSDs will help somewhat in that case).
We'll check out whether it would be feasible to add a 60 second safe margin before timing out.
Thanks for the reply Janne.
I paid $240 for my 960 to have my eye candy, hate have to give it up online. I even drop grass setting to High before I tried loading Mixed 3 and the guys still got time out because track loaded to slow. I would hate to have to turn off grass, like a lot of players I am finding out, have!
I don't do much offline except for some modding. Must my time is spent racing and derbying online with Wreckfest.
