As I wait to give the biased engine a good run this week, I have accumulated a bunch of scenes ready to test.
I decided to test one with Thea's unbiased engine while I wait, but only running for 10 minutes (I get bored of watching a render after that).
I post the original render size, the render was run with only sun and an alpha channel, the desert is post added, all else is mesh.
I used an i7, 12Gb ddr3 RAM, set on low priority (if that even effects speed I dunno)
Forget about the...
