As the standard stuff happens video starting to be leaked out from gameplay videos just remember not final product so not much point complaining
I haven't noticed any graphical improvements from the 2016 game...
When you can tell all you want us to know about F1 2017.)The two alternative layouts were confirmed already:
Texas "Short" (more like shorter - cuts straight in to back straight after S'es);
Bahrain short (Paddock layout - google it)
There will be 2 more - Spoiler: One in Europe, and One in Asia. It's just current possible alternative layouts of current tracks.
Also E3 videos doesn't look good - my current Beta build looked better...
EDIT: VR - not sure fully yet, but there's something... Sadly I can't spoil yet.
