As todays commit 7b4276d7acf2e0f77044cb50caa6ad936fa78786, "r600g,radeonsi: Always use GTT again for PIPE_USAGE_STREAM buffers", refers to this bug: The patch helps tremendously against stuttering (~0.5s pause irregularly about twice a minute) in Borderlands 2. Kernel is an unmodified agd5f 3.18-next, hardware r9 290x.
Thanks !
That mesa patch also reduced my stutter in BL2. Right now (I have just tested 5 minutes) I only get short lags when the game must load new areas/models (e.g. making a turn or entering new map zones). I'm on 3.17 rc7 (Radeon HD 7870).
The stutter was also very noticeable in EuroTruck Simulator 2, making the game almost unplayable. There still a few stutters in this game, so I would say the stutter is not completely gone (even though my BL2 experience is good).
