Your laptop has a powerful graphics card, but Resolve edits like it is running on a calculator. The reason is often simple: on Auto, Resolve picked the integrated GPU. Here is how to point it at the right card - permanently.
Most modern processors carry a small built-in GPU for everyday display work, and many laptops and desktops add a second, dedicated graphics card for heavy lifting. DaVinci Resolve on Auto is supposed to choose the strong one, but its detection regularly goes wrong - after driver updates, on machines where the monitor is plugged into the motherboard, and on laptops that hide the big card until an app asks for it. The result: laggy playback, GPU memory complaints and the configuration warning. The fix is to stop asking and start telling.
If your dedicated card is not in this list at all, Resolve cannot see it - that is a driver or hardware-visibility problem, not a selection problem. Install the current driver for the card first, then come back here.
Leaving the integrated GPU ticked alongside the card invites Resolve to split work onto the weaker chip. One card, clearly chosen, behaves better than two cards sharing.
Close DaVinci Resolve completely and open it again. GPU mode and selection are read once, at startup; changing them mid-session and continuing to edit proves nothing. After the restart, return to Memory and GPU and confirm your manual settings survived - they should now show exactly what you ticked, with Auto off.
Open a project that used to stutter and play the busiest part of the timeline. On Windows you can also open Task Manager, go to the Performance tab and watch which GPU climbs when Resolve plays - it should be the dedicated card, while the integrated GPU stays near idle. Smooth playback plus the right GPU graph is the real confirmation; the settings page alone is only a promise.
Watch the video to see the GPU list inside Resolve, which entry is the integrated chip, and the before-and-after playback difference on the same timeline.

No. The free version of Resolve uses a single GPU for processing on Windows and Linux anyway, and mixing a strong card with a weak integrated GPU does not add their power together - it usually causes the warning and uneven performance. Tick the dedicated card only.
Resolve only lists GPUs it can initialise. Update the card's driver from NVIDIA or AMD directly, restart the computer, and check again. If it still does not appear, verify the card shows up in Device Manager (Windows) - if the system itself cannot see it, that is a hardware or seating issue, not a Resolve setting.
