If a game isn't on Nvidia's list, ReBAR won't actually be used even if BIOS and Nvidia Control Panel both show it as enabled. The open-source Nvidia Profile Inspector tool lets you check and override these per-game driver settings. Starfield is cited as an example where manually enabling ReBAR before Nvidia's official support yielded a 5–10% FPS improvement. The advice is to benchmark before and after enabling ReBAR manually, since results vary by game and forcing it isn't always beneficial. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### Why is Resizable BAR enabled in BIOS but not actually working in my games on Nvidia? Enabling ReBAR in BIOS only satisfies the first requirement. Nvidia's driver profiles act as a second layer, enabling or disabling ReBAR on a per-game basis via a whitelist. Even if Nvidia Control Panel shows 'Resizable BAR: Yes', that only confirms system-level support — the driver must also whitelist the specific game before it actually uses ReBAR. _Developers and enthusiasts tracking Nvidia driver profile changes for specific games follow those updates on daily.dev._ ### How do I force Resizable BAR for a game that Nvidia hasn't whitelisted yet? Use Nvidia Profile Inspector, an open-source tool that lets you override Nvidia's default driver profile settings on a per-game basis. Select the game from the drop-down menu and enable ReBAR for it specifically. Benchmark the same section before and after the change to verify whether it actually improves performance, since results vary by title. _PC builders experimenting with GPU performance settings find relevant driver and hardware coverage on daily.dev._ ### Did manually enabling Resizable BAR in Starfield before official Nvidia support actually help performance? Yes, players who manually enabled Resizable BAR in Starfield using Nvidia Profile Inspector before Nvidia added official support saw a 5–10% improvement in FPS. Nvidia later added official ReBAR support for Starfield through a driver update, but the manual override worked in the interim. _Keeping up with Nvidia driver updates and game-specific optimizations is easier when the relevant news surfaces on daily.dev._ ## Similar posts on daily.dev -
