Bug: Game uses excessive CPU and GPU due to unlimited FPS trying to run as fast as possible.
Workaround: If possible use your GFX driver to limit the game FPS to 60 or lower eg. film/TV speed of 30 FPS.
For ATI/AMD owners this is the function named "Radeon Chill".
Due to the type of game this is there is no benefit of high frame rates, as the game still runs smooth, and your fans are quieter.
This game is really very nice and polished, and I highly recommend it, but lacks a few polished-package touches like screen size and mode (Unity can offer the default config window at the start. No shame in using that). A minor gripe but does affect the amount of users that can play it.
The lack of being able to set the volume in the game is my most frustrating issue due to how ear burstingly loud it is compared to the rest of the desktop audio (eg. people in voice chat).
It is lovely audio and production but I'm not sure the people living next door appreciate it as much.
However, again there is a workaround by locating the game in the volume mixer for your operating system and set it there.
Dev Tip: From a game dev point of view, it is very common for people to overlook the menu page being as resource hungry as the actual game.
Unless there is a good reason not to, it is always worth using a stricter FPS limit on the menu pages or when paused (this is sort of what Radeon Chill does).
