I don't like My computer... My 8 year old computer gets the same FPS as my 1 year old computer. Oddly, while playing graphicaly demanding games the computer seems to be a super computer. (maybe it has something to do with dual core... I have 2 cores, both are dual cores)
I think my lowness may have something to do with dual core-ness I have two cores/processors (whatever you want to call them) and each are dual core. I would imagine TPT only uses one core or even half of the core. I say that because when I flood fill the screen, It lags heaps, but my cpu usage ranges from 20-50 % at that point.
At the moment I have two games open, and on an empty screen I have 30-40 FPS
