I am noticing that the lag is happening in association with some programs more than others. Firefox 22.0 seems to slow the system down more than most other software I commonly use. This happens even when it doesn't appear to be loading anything or doing any significant work. The mouse pointer lags most when it is over the FF window. However, some lag happens also with LibreOffice 18.104.22.168. I use these programs more than any others. It could be that it would happen with nearly any software open. These are just my most used apps, so I notice it more.
It seems like my system should be able to handle these better. Is there something I could do to make this better? I don't have a large amount of effects toggled on.
I am not a hardware guru (obviously). What would be most likely at fault with these issues. My Intel(R) Core(TM) i7-3770 CPU @ 3.40GHz1600.00MHz, low RAM (8GB), my NVIDIA GeForce GTX 650 card, or software?
UPDATE: OK, my whole system is definitely laggy with almost any program at all open -- even Dolphin! When I try to actually do anything with several programs open, I either can't, or it is extraordinarily slow. Why would this be?
