Hi Eero, I sent you the full compare test result for the Mika's patch, and base
on the each benchmark single cycle test result, we did see after applied Mika's
patch, some case did show less than 1/2 FPS vs. without apply patch.
such as: 
Half_Life 2
GLBenchmark v2.7.0 FillTestC24Z16
GLBenchmark v2.7.0 FillTestC24Z16_Offscreen
SynMark2_v6_0_OglFillTexMulti
SynMark2_v6_0_OglPSPhong
