Im just trying to get a 100% silk smooth fs and am curious about what the major system bottlenecks are that really hinder fs performance.

Most say FS is CPU dependent than anything else. So as a very general answer it would be the CPU. But what the bottleneck is depends on what the config is on a computer. For example if you only have 256MB ram that's your bottleneck right there.With in FS9 what hits my performance most is texture loading and cloud rendering. But that's just how the FS engine is. Nothing we can do about it.Jason
