Hi, I've had p5 since it came out... works fine now.. haven't had a crash in months.. very stable... but .. last night I was bored and decided to play with p4.. loaded up v3 and some global ilimunitation.. and hit render.. to my suprise.. the thing flew.. it generated shadows for about 20 light in under 30 seconds.. so then i said to my self... hold on a sec.. let's try the same scene in p5.. (latest release).. guess what twice as long.. tool over a minute to render the same 20 lights.. (using the p4 renderer in p5).. the favour I need... is could some one who has p4.. and p5 do a quick render in both... with multiple lights and shadows.. and see if there's a diffrence between p5 and p4.. maybe it's just my setup... thanks in advance...
