           Summary: [Regression] [Bisected] Slow performance on R9 270X
                    (pitcairn) on mesa 11.1
           Product: Mesa
           Version: git
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: critical
          Priority: medium

I get very slow performance in games with my graphics card (R9 270X) since mesa
11.1. In mesa 11.0.8 everything was running fast as usual.

I tested dota 2 and Saints Row 4. Both work fine with 11.0.8 and are unplayably
slow (<=1fps) with 11.1.

I bisected this issue to commit 525921ed51176255474c73adacfc6801a7bf2783.

If you need more information, please tell me.
