It looks like v595 finally got the “exploding meshes” (bug 5649065) in Second Life fixed: I’m still stress-testing it, but so far could not reproduce this bug on my two most powerful PCs (RTX 5070 Ti and RTX 3070).
However, the Performance mode idle clocks are still broken (see the last paragraph in this post): by the way, do you have a ticket number for that bug ?
