Myself and several of my guildmates are having an issue. We can have 10-30 mobs on the screen fine, but if we agro 5-10 or more we lag out to the point of having to fly away and having it clear within a minute or so, or in cases like the FB having the computer lock up. (not a ctd) but lockup requiring a restart. Happens in Glenn with the Chavez as well.
I downloaded monitoring software and the heat for cpu and video card are fine. Have tried adjusting the settings for video and sound, have updated video and sound drivers. Ran the game in 256/32bit/16bit color, tried different compatability modes and tried running it not in comp mode. Ran in 640/480 and not, ran windowed and not. Adjusted in game graphics as well.
AMD Athlon II x4 630 Processor 2.80ghz
ATI HD 4600 video
4gb ram
Win7 64bit
Running out of stuff to try, any further help on this would be appreciated.
