Thank you guys for the answers!
I downloaded the newest Viewer from LL earlier and I noticed a huge difference in how slow things were. I tweaked the settings lower and things seemed fine. However, I opened up Task Manager and found that in the Memory column, instead of what it normally might have been (200,000-300,000k at most on a bad day), it is now over 1millionK under Memory. I exited and opened a new instance and encountered the same numbers. Anyone else having this problem? Or, is it actually a problem? x3
