I'm new to serious editing and the free version of Resolve just threw this at me:

GPU Memory Full
Your GPU memory is full.
Try reducing the timeline resolution or the number
of correctors and effects applied to this clip.
The timeline is 6K RAW clips, and I used a heavy color grade a lot. I don't really understand where all the GPU memory goes. Any advice?
Any tips on settings or workflow changes are welcome. i want to finish this project now and learn how to avoid the error next time.
