As I mentioned in bug 68235, with 69e0b57a91adca2e3eb56ed4db39ab90f3ae1043 the
driver did not enable dynamic performance level adjustments since it caused
hangs. With that commit the GPU always stays in the lowest performance level
which is why it's stable.  The hangs were fixed by
4da18e26e0cc2387597ff57ac33df1bc6369fbed,
7a80c2c9a957b1ab056fac235140ebd6c43d9831, and
779187f2c3e69b8c06488538e0fd9fd02163359e and dynamic performance levels were
enabled in commit 7ad8d0687bb5030c3328bc7229a3183ce179ab25.
