Basically, the lag started around the time when Runescapes Graphics were totally revamped. (Around July last year) It was in the first few weeks of the update, and for some reason High Detail stopped working, so I tried to upgrade my ATI Radeon X1200. The installation didn't work, it just eventually said:
ATI Catalyst Install Manager has stopped working.
Note: The HD not working thing was just a Runescape bug, which was fixed the next day.
This was also around the time that I went from 2GB of RAM to 4GB. I MIGHT have bought it because I was experiencing the lag, but I really can't remember.
I've tried cleaning up my laptop in various ways, reinstalling Java, upgrading my Graphics card (which I found a fix for), scanned with SUPER Anti Spyware, Malwarebytes' Anti Malware, and I have Kaspersky Internet security 2008, which I have scanned with. All threats from those scans have been quarantined.
I'm out of ideas and still lagging.
On a brighter side, I've got the scan results
Thanks much, Pteri
