Also: for BW2 please check you have the latest Nvidia drivers, and that DLSS is turned on (I would recommend "balanced" setting). This will make a *massive* difference to performance and visuals.
The game is very intense of VRAM (and RAM in general) because of the huge amount of fidelity we are providing, both with foliage as well as what is called "real virtual textures" (RVT's) which allow us to do unparalled terrain blending and many other things.
The game textures should look good. If you run out of VRAM on your GPU, then textures will not load in well and you may get some bad looking textures.
In terms of drop length, there are many different lengths you will have on drops. including outpost prospects, which have unlimited times. One of the purposes for the beta is to explore what is interesting, fun, and how people play - so our team doesn't make assumptions and we can make changes to the game before it becomes solidified too much.
