Unfortunately, I have 660gtx onboard. It cannot render this scene realtime in good quality.
Last file (test3) was exported without AA 1280720. It was “draft quality”
Previous scene (test2) was exported with 25601440. And antialiased each image. Resulting 1280*720. There is no flickering.
.exr sounds good
Sorry for late answer. I was very busy at work. And almost forgot about thread.
