Hello,
I’am new for corona test, i have a BI XEON E5 2620 V2 (12 CORES- 24 Threads) 2.1 gh, nvidia quadro 2000 and 3DSMAX 2013 but render with corona is very slow and Interactive rendering not work.
Please do not post the same mesage to multiple forums, thanks.
Regarding to you problem:
- When your entire problem description is so vague as “it is very slow”, I cannot give you better answer than “use better settings”

- Interactive rendering is not available in Alpha 5 build. You have to wait for the next alpha release.
