The other bug was done. Th
Is this fixed now? I've had the same or a similar problem and it's fixed now. I thought it wasn't fixed for a while until I discovered that limiting the frame rate to 60 is really bad for performance in Borderlands 2...
The stalls were reduced a lot in February 2016, but they didn't disappear completely.
radeonsi now has an end-to-end shader cache and glthreading which is enabled by default for Borderlands 2. These issues should now be mostly gone, there is not too much more that can be done. Closing.
