Just got a brand new x1650 today, and I'm having the most horrible lag on Second Life. I've tried all of the settings from Low to Ultra with no results. I've already installed the most recent Catalyst version. I've tried changing the bandwidth in SL prefs because I read someplace that might help. Nothing I'm doing is working. Are there any known issues with this card and SL? SL worked a lot better with my onboard Nvidia GEForce 4MX Integrated GPU, so I'm finding it pretty hard to believe that this card is worse than the onboard graphics controller. I think I've got a pretty decent system, but I keep going below 10fps. Can anybody please help.
