Low strengths work OK now, but this patch seems to have made denoise
stronger. Maybe I am looking at the wrong material, but more than 0.2
for sharpen or denoise looks too way much.
Benchmark wise sharpen seems cheap, but denoise at full strength is
expensive, and comparing full on before and after the patch on 1080
material shows that it's doing more work.
This is with my card (HD4890) on low (239840 kHz) as for htpc it's
quiet, testing a 60 sec stream, roughly -
no options = 16 sec
full sharpen = 24 sec
full denoise before patch = 48 sec
full denoise after patch = 66 sec
This is current gits so 2D tiling is on, FWIW vdpau is by far the
biggest gainer from this of anything I've tested - in the past I could
easily compare with R600_TILING= , but I guess I can't turn it off for
textures any more.
