There is in fact a way to disable lens flares and shadows in the ini files. I don't remember exactly which file and what the variables are called exactly. Ctrl+F in the ini files looking for lensflare and shadow should find it though.
Disabling lens flares and shadows in the advanced graphics settings does increase performance. So I don't know if lens flare and shadows are on regardless of client settings, so it might not be worth the effort solely for those things if there is already performance gain from turning off the built in settings options. There used to be a thread on the forums with a lot of changes you could do to the ini to improve performance specific to hawken but idk if it still is around in the archives. Might be worth a search.
Also if you google search ini config for UE3 you can find some general optimizations you could try. [at your own risk]
Good find on the tree stuff, I am gonna try to see if it increases fps tonight. Good chance it won't though. The sky boxes in Hawken are pretty impressive....and taxing on the pc.
