Please give us some more information:
-what is your hardware?
-why did you change GI/AA balance to 5? Do you even know what it does?
-did you just take the scene made in Vray, used a converter and hit "render" without tuning materials manually?
this my hardware
ram 24gb
prosesor intel i7 950
-why did you change GI/AA balance to 5? Do you even know what it does? I just tried from the value of 16 to 5
The amount of GI samples per each sample antialiasing.
Higher values will increase is a sampling of Global Illumination, resulting in cleaner indirect lighting, glossy reflections, refractions and translucency. Lower values will increase is a sampling of antialiasing and therefore improve quality of fine geometry edges, Depth of Field, and Motion Blur.
Setting this value under 2 or above 64 is not recommended.
