I found that even people with hi-end have the same problem in MONTHS old post. They don't seem to give a damn about it.I'm not sure if your computer is just awful but I'm pretty sure they'll be adding it as an option later on.
The UI is bad anyway, it's kind of the one which force you to do walk through everything to actually find out what you want to do. I'm not sure if there is any tutorial at the moment, but for me it was fairly difficult to navigate even with experienced user telling me what to do.
I can understand lack of any help to minority, but I find this game just as another example how retarded valve hype is. They can't do anything right.
