max 16 sp4, win 7 sp1, RC9
with unchecked the new new direct light solver checkbox, I am still experiencing cpu usage increase to about 25 when select a coronaCamera even with a blank scene. with interior scene, heavy lag, low fps, slow IR..
compared to RC5, I guess it is the savest build for me.
1. open taskManager (always on top)
2. open blank scene
3. create coronaCamera
4. select it
5. cpu usage increased
6. deselect it / create non-corona camera
7. cpu usage 0
