Hi,
Just installed version 1.5 and have been doing some speed tests.
A scene that rendered at 39 Ms/sec on 1.2 and 1.1 now renders at 23 Ms/sec using direct lighting. Using path tracing the 1.2 and 1.1 versions render the scene at 13 Ms/sec, while 1.5 manages approx. 9 Ms/sec. I have loaded a wide range of scenes and 1.5 is consistently slower. I have the latest NVidia drivers installed (although the same results were present on an older driver before I updated). I have a 3GB 580 and a 1.28GB 570.
Anyone else seeing a similar drop in speed?
