Revision cd6129d by Sergey Sharybin (master) October 6, 2014, 10:36 (GMT) |
Cycles: Workaround dead-slow expf() on 64bit linux Single precision exponent on 64bit linux tends to be order of magnitude slower than double precision version even with single<->double precision conversion. Some feedback in the mailing lists also suggests that logf() is also slow, but this i didn't confirm here in the studio yet. Depending on the shader setup it gives ~3% with the secret agent shot and up to around 15% with the bmw scene here. |
