In this video I’m showing you three simple methods to improve DaVinci Resolve Fusion performance, especially when your comp starts feeling heavy and playback gets painful. First, I disable a few viewer-only settings so Fusion stops wasting time drawing stuff I don’t need while I’m working. I right-click the playback bar and untick High Quality and Motion Blur—your final render won’t lose quality, because this only affects the viewer. I also disable “Updates on Node” (right-click a node → Mode → untick Updates) so nodes don’t keep updating during playback; they’ll freeze, but the viewer updates when I actually change something. Second, I use Proxy mode from the playback bar. Proxy basically reduces the amount of pixels Fusion renders for the same viewer resolution, so performance jumps up. You can control proxy quality in Fusion Settings → General → Proxy, and I usually pair this with disabling High Quality and Motion Blur to fully enjoy the speed. Third, I lean on caching. You can cache to disk or save/cache specific nodes to make Fusion play smoother. The key takeaway is: organize your node tree—don’t hesitate to use Merge nodes and split your comp into parts so caching is easy and doesn’t become a mess.
