With a decent PC, I seem to have less-than-optimal graphics performance in Second Life -- looking for experienced advice. Using the most current SL browser (1.23). Client is an Intel, dual core 2.13 GHz, 4 Mb RAM, on-board S965 chip (Intel Extreme Graphics) (current drivers) (yes, I know the chip has gotten bad reviews).
Per "older" KB advice I set the processor affinity down to one. Hard drive is new, relatively empty, and kept defragmented. Unnecessary processes have been killed. Network is cable but business-class (telecommute grade upload). I suspect I don't have the openGL optimized, in my ignorance of what to do. The game graphics are set to to minimal load, with minimum draw distance, etc.
Symptoms basically that the av responds in a jerking manner, or freeze framed. In worst-case lag, the image refresh appears to be no better than once a second. Clearing group cache doesn't seem to provide relief. Seen using either Ubuntu LINUX or XP Home.
Thanks in advance, fellow gurus.
