On my system I get the following just SE of KSFO facing the city at ~155 degrees): - No buildings: 27fps - Random buildings (density 1.6 though it doesn't make any difference on my system): 27fps - Urban Shader (Quality 2): 22fps Skydome switched on (apologies if this != Lighfield): - Random buildings: 20fps - No buildings: 21fps (Note that I'm see a lot of variability when I start changing values in the Rendering Options menu and then reloading the tiles. On startup with Random Buildings switched on, I get 35fps) So, it looks like there's a lot of variability in performance impact depending on people's specific systems. -Stuart ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
