I'm having an issue on a system with an AMD Radeon HD7850 running on Windows 7 64-bit. With anything but the 13.4 official drivers and anything prior, which are 4 months out of date now, SL loads into the world, some parts of the world load, but my AV does not. Within about 5 seconds, my viewer crashes without warning. This happens on Niran's, Exodus, Catznip, and both the current and beta LL viewers. This has been happening for months with anything beyond the 13.4 AMD release. Up til now, I've had no pressing reasons to update, but as of 13.8 beta 2, there are significant performance and latency improvements across a number of new games, and it's forced my hand to update my drivers, meaning now I can't run SL. No other programs have this issue, and some quick googling points to updates to OpenGL in the latest AMD drivers having to do with it, with SL failing several OpenGL calls when crashing on the new drivers. I have no idea how to see this issue addressed, as no other programs running their rendering off of OpenGL (such as Awesomenauts, which I play), have these crashes, and I feel that contacting SL support will push nothing along. I'm primarily concerned with finding a viewer that might run with the latest drivers and seeing if I can find others having the same issues. I don't expect this to be fixed, of course, as judging by Linden Lab's usual response time, I imagine this might be fixed in 2-3 years, assuming the drivers don't sort themselves out eventually.
