The past 3 days, SL has been almost unplayable for me. I have no idea if I need to do something other than clear cache, which is normally everyone's first suggestion (tried that in the first moment of difficulties). I have uninstalled, re-installed, tried the updated game, tried Windlight, nothing. In fact, Windlight just gave me a game of all black/white textures and I couldn't see a darn thing, so it was uninstalled pretty darn quickly.
I log in, I render/rez as usual and then when I try to walk around, everything starts to stammer, my Av gets turned around and I have zero control of her. I basically call it "her getting electrocuted". It's a major struggle to get from one location to another.
I can carry on conversations - clothing changes take longer than normal - TPing is about the same time. It's the movement/walking/dancing/etc. that is causing me to have "electrocution fits" and in turn, giving me so much RL grief I want to scream.
I haven't changed any hardware in my system. The only "new thing" is that I added a fish tank beside my computer. At first, I think the motor of the aerator was making my monitor shake a bit on the far left, but I separated the two further apart and now the monitor isn't shaking/being affected.
My son has been playing World of Warcraft on my computer with no problems, so I can't pinpoint what else might be going wrong for SL to giving me problems. HELP!
