Entire PC locks up in various mesh compatible viewers

Recommended Posts

Encountering a problem where my entire PC freezes while in Second Life. I can log in at certain areas, move around for a while, then at  various places, it will Freeze up. It seems to be a problem with Mesh, as the places this problem occured were at The Mesh HQ, and Mesh Sandbox areas. I can see meshes just fine before the crash. It freezes up instantly during login if I login in my last location instead of a new one.

Problem reproduced on:

Firestorm Beta 3.0.1.22566

Second Life Viewer 3.1.0 (243176)
Second Life Beta Viewer 3.2.0 (243350)

Second Life 3.2.1 (243698)  (Project Viewer - Mesh)

Problem not occuring with Phoenix Viewer 1.5.2 (1185), which doesnt support mesh - another reason I think it might be mesh causing the problem. However, before the official mesh launch, I was able to use the project mesh beta viewer just fine.

Graphics drivers fully updated.

Tried various graphics settings, including unchecking "Enable OpenGL Vertex Buffer Objects", problem still occurs.

The current LL SL Viewer and Singularity 1.6 are both ocasionally crashing on startup, or BSODing my PC here. ITs becoming a bit of a problem for Mesh development.

 

CPU: Intel® Core2 Quad CPU    Q8400  @ 2.66GHz (2666.69 MHz)
Memory: 3583 MB (i.e. 4 GB under a 32-bit OS)
OS Version: Microsoft Windows XP Service Pack 3 (Build 2600)
Graphics Card Vendor: NVIDIA Corporation
Graphics Card: GeForce GTX 460/PCI/SSE2
Windows Graphics Driver Version: 6.14.0012.8558
OpenGL Version: 4.2.0

It did it under both this version and a previous release of the NVIDIA drivers. The only common factor i can see between our systems is that we both have GTX 460 graphics cards.

It's not been well-publicised, but the LL Viewer, in its current implementation, has been having problems with nVidia graphics cards. There are JIRA entries on the subject, and the last report I saw claimed that a fix was going through QA testing, but the timing was wrong for it to be in the current download.

It's not quite a bug: the Viewer code uses some OpenGL calls which are terribly old and recent drivers don't handle them well.

I wouldn't myself class Mesh as being out of beta, because of these problems. It was interesting to see, when Kirsten's was still available, that the Linden Viewer 3 was much slower than the Kirsten's Mesh beta, based on an earlier version of the code. This occurred even when no Mesh objects were around. Similarly, Cool VL Viewer retains quite stunning speed in its Mesh-compatible version.

All of this might have nothing at all to do with your system crashing, but it's a good starting point for a fix. Stepping bacl to the version of the nVidia driver from about a year ago--I don't recall the number--has been recommended by some, and there's also a very recent new driver. nVidia has had reports of problems with a lot of older software.

I suppose that Second Life is an unusual game for getting the updates it does, but, necause it does keep gtting updated, it's a little worrying that this ancient problem surfaced.

Thanks, I hadn't come across this when looking for a solution before, all fixed now.

Note for anyone else trying to fix it this way - the 266.58 drivers from Jan 2011 did not fix the problem, but the oldest available drivers, 260, from Oct 2010 did fix it. Didn't bother trying anything inbetween the two.
