I have a tile wall, with 2d displacement (everything is default), but it brings my scene to a slow crawl when rendering. With displacement it renders in 11 hours and without it renders in 3 hours. I have a dual Xeon and I remember hearing there might be an issue. Any tips?
what are your displacement settings? what kind of texture are you using (size, format)? are you using max bitmap loader or vrayHDRI loader?
