I think everybody should just chill out, try to download new drivers, and stop complaining about it. Thats not going to do anything.
It would be a sad day if that were true. "Complaining" is a way of letting HTC know there is a problem. Read the boards over the last month or so and it's pretty clear there is a problem for a good number of players.
The question that is still up in the air after a few long weeks of rotten framerates is if HTC values its improvements in eye candy over the playing needs of a portion of its customer base.
I would think removing some excess trees would be an easy, temporary fix, although I have to honestly say that I'm not sure of this. Maybe it takes time to chop some virtual trees from a mountain top or a field miles from any vehicle spawn point. Would it solve the problem? I don't know. But if the problem isn't caused by the trees it would go a long way toward convincing people.
Or maybe HTC is letting it's silence on the whole too many trees issues speak for itself. Then maybe we had better "all just chill out" or look for greener, albeit treeless, virtual pastures.
