Second Life seems to insist on writing to the screen anytime it feels like it, instead of writing only during the the vertical blank interrupt. This makes for flicker when other things are displayed on top of it. I used to be able to get it to draw only during VBI.
Any help or info available?

Since it's using OpenGL it would be up to the video card's firmware and the OpenGL driver to decide when to update, no?

emmm.
Vertical Blanking Interrupt?
If that's really what it is, then sounds like your monitor or display card is about to fail.
Its a CRT, right?
What does the screen look like? Does it Flash white? Does the image pull in suddenly from the edges, then expand back out?
Are peoples/objects in the wrong place on screen?

From: Argent Stonecutter Since it's using OpenGL it would be up to the video card's firmware and the OpenGL driver to decide when to update, no? In the OpenGL settings for the card it is set to Always ON for Wait for Vertical Sync. I'm not sure that SL is respecting this setting, or maybe SL is and something else is messing it up. Hmm, the OpenGl part of things would only deal with SL , the rest of the drawing and compositing would be done by normal Windows methods. The Direct X setting for Wait for Vertical Synch was set to always off. I'll change that and see what it does. In the file of strings extracted from the secondlife.exe file, there are lines that say "keeping vertical synch" and "disabling vertical synch". I'm pretty sure there was a place to set this for SL in the past. From: someone emmm.
