A new update for Resolve is available. I use the free Lite version regularly, it’s easily the best free grading suite out there. The Lite version is only limited by HD resolutions, a single GPU and no noise reduction. This suits my F3 perfectly as it’s virtually noiseless in any situation. The full version is 4K and multi GPU with noise reduction.
My i7 3770K with a GTX680 4GB and 32GB of RAM plays back any amount of nodes I’ve needed in real time without a glitch.
