Aces New Project

When I create new projects why would i not want to always select ACES1.0 vs No ACES support even if i have no intention to work in ACES. Is there a downside to not building all projects with ACES enabled?

No real downside, but it adds more controls that you may not need, and it also hides some of the camera controls for Red, Sony, etc, because they can’t used if you’re doing ACES work.
