<pre>Tested the effect of just this particular patch, on BDW GT2, for all
GLBenchmark / GfxBench, GpuTest, Unigine demos and SynMark test-cases (3 runs
each):
-6% Unigine Valley (fullscreen GL)
0% GLB 3.0 T-Rex (fullscreen GL)
+2% GLB 2.7 Egypt (windowed GLES)
+4% GLB 2.7 T-Rex (windowed GLES)
On other tests there was no effect that wouldn't have been within their normal
variances.
Wendy, there have been mentions of PMA issue having much larger benefits (on
HSW) in Valve games and Lightsmark. Could you mail me information about the
performance before and after the indicated Mesa commit in Lightsmark and all
the games?
NOTE: You need to do that test with the fixed X intel driver (which came after
this commit), so that that issue doesn't distort the numbers.</pre>
