I have been having lag on all my games including WoW and Team fortress 2. I used to be able to run them smoothly on high settings but now on WoW I lag on the lowest settings. WoW is a very easy game to run. This doesn't make any sense at all considering I have windows vista with an nvidia geforce 9100 video card, an amd phenom quad core processor, and 5.7gb RAM
The lag seems kind of strange. For example, WoW will say I am getting 30fps, but it will feel like 3fps. It seems to slow down and speed up rapidly.
I got a new modem and had my isp check my internet connection. So it is not my internet. I reformatted my harddrive and restored my computer to its factory settings so I don't think it is a software problem.
I don't know a lot abbout computers so I would like to know why I could once run games well but then suddenly stop running them well.
It must be a hardware problem, but I'm not sure if it is my video card. your thoughts?
Hard to believe "ON BOARD" video can play some games at all. If you think they played good before you may have maggot ware on your computer. Run AVG anti virus or go to Trend Micro House Calls and do a scan. Clean up your hard drive and do a defragg. Check your virtual ram settings. What opsys ?
