The situation has somewhat improved after todays patch in that the main menu is now almost asymptomatic and the sin menu appears to be a bit faster aswell. Thank you for that :)

However, the underlying behavior remains the same. Any view with a lot of input fields will still cause, what looks like GPU "thrashing", completely tanking utilization and thus performance. For example the controls menu will still not run above 15fps (no improvement over 2.0), irrespective of graphics settings, including setting the resolution to 1024x768, with the same symptoms as before.

I just did some further testing and found that opening the controls sub-menu inside the game options reproducibly lowers the FPS into the mid-teens. This then persists, even with the menu closed, until I navigate away from the control sub-menu or close and open the options again (probably because it defaults to the graphics sub-menu).

Here is what my GPU graphs look like by that point: WftO_bug.png

And by comparison with no menus opened: WtfO_non_bug.PNG

The button to upload files is the rectangle with the pointing upwards at the top of the text editor. The default path for the log file is:

As an aside, you'll have a much better chance of getting your report looked at if you strip all the creative writing from your post. Just think of the guy/gal on the other side having to parse the bits of (maybe, maybe not) relevant info from a piece of prose just to get an idea of what the problem even is so they can do their job.
