Unfortunately quite a few bugs have crept in after the rewrite that came in 1.14.0.0 . All of my currently submitted patches have been accepted by Linden Labs and should appear in a Release Candidate soon. This should bring particle possibilities to their best level yet (beating pre-1.14.0.0 too).

			''Performance profiling of Second Life viewer''<BR>
			I profile the Second Life viewer using AMD's CodeAnalyst. Once I've identified hotspots I check whether these can be improved in order to gain more performance. As particles eat a lot of CPU I'm profiling that particular area still while fixing all the particle bugs I can find.
