A few posts back, I mentioned that something had happened to increase my frame rate, the "smoothness" with which Second Life performs. My frames per second (fps) had gone way up, from an average of maybe 15-20 to 50, 60, or even more. The improvement was so significant that it even enabled me to use Shadows for the first time ever (barring the occasional photograph). Just what it is that caused this, I have no idea.
Now a new factor has reared its head. In my home region of Masocado, at ground level, I'm seeing some terrible lag...but ONLY when I face a particular direction. Face one way, fps = 50. Face the other way, fps = 2. The problem does not occur if I'm under the water, or high up in the sky.
From that, I suspect that there is some texture out there, or some object, that is really hammering my graphics card. But where is the darn thing? I've moved to various parts of the sim, and tried to "triangulate". The problem seems to be coming from somewhere on the docks, or the condo tower building, or the new beach house by the towers.
(Although my partner Cindi reports a different result. She gets a change in fps with the direction she's facing too, but for her it's a different direction!)
I started de-rendering things in the hope of finding the culprit. When I temporarily erased the boats at the docks from my sight, my fps took a jump up, and I rejoiced briefly. But then, back it plummeted again.
So far, I have no idea how to find or fix the problem, but it's making life at Masocado less than pleasant. If anyone reading this has some ideas, please post a comment here or IM me in world.
