Ok I built my PC 2-3 days ago. Got Ubuntu 12.04 LTS up and running.
Got my nVidia GT220 card finally working and now when I play TF2 it plays fine but after about 15 mins of gameplay it pretty much came to a standstill on a loading screen.
My mouse started to lag and barely move after a while. This also happened on DOTA 2. I believe it's my RAM. I have a Mushkin 2GB DDR3 installed. When I look at the hardware, though, it shows it as 1.4GB.
Is lack of RAM problem? Also my other parts are a AMD A4 Llano APU, MSI a55m-p33 mobo, and the OS and games are on a Toshiba 500GB laptop HDD. Can anyone give any insight to this?
