I have noticed an odd viewer 'freeze' a moment or two after crossing into a new region. I don't often fly region to region but with the new improvements, I have been taxing the viewer. The new Linden Home regions are particularly 'heavy' and where I have been testing. Object and texture loads, are speedy but this freeze stops the viewer for about a second. I have tried with GLWorkerThreads on and off. I have noted that tailing the log this is the line logged during the pause:

After crossing a region border (or after a far TP, or after login), the viewer auto-refreshes the objects visibility to fight "missing" (or disappearing) objects and objects near the border that get moved out of place (and therefore appear in a wrong place on the screen). Viewers not doing it simply suffer from these well known "glitches" (likely due to a race condition in the objects list refresh and the sending of the "interest list" data by the sim). This incurs a short freeze (normally, well below one second: around 250ms or so, at 256m draw distance), but the more objects in the object list and the slower your CPU, the longer it takes... You may control the delay after the login/TP/sim border crossing via the "ObjectsVisibilityAutoRefreshDelay" (setting it to 0 disables the auto-refresh), which defaults to 2 seconds (if objects are still missing after the auto-refresh, you may want to try and increase that delay to 3 or 4s). Note: I split this into a new FAQ thread, since it had nothing to do with the experimental viewer. |

No problem on the new topic. I have always noticed the 'blip' with region crossing, it just seems a bit more severe (longer/full hang) in 1.29.0. This could be due to the regions I'm in having a large number of objects and complexity. It could also be that I'm transitioning regions too fast as the effect seems to get worse the more regions I cross. |
