FAQ

Can Swapper do RTX 4090 setup in Subnautica?

Yes. Community runtime unlock with 24 GB VRAM headroom. Install the route, test borderless, tune F8 where supported, and keep the backup.

Do I need native DLSS in Subnautica?

No. Native builds upgrade in place; otherwise the Feeder route supplies neural inputs.

How do I undo everything?

Select the game and click Restore originals. Uninstalling the app alone does not touch game folders.

What does the F8 overlay do?

It opens Swapper's own panel over 64-bit DX11/DX12 Feeder and RenoDX games so you can move Style, Intensity, Structure, Skin and stabiliser sliders live.
