RTX 4090 presenta problemi con Need for Speed ​​Unbound che possono essere risolti solo con un aggiornamento VBIOS

Maestro del controllore


Bisogno di velocità senza limiti (NFS Unbound), the latest entry to the popular genre-defining race sim by EA that launched today, unearthed a problem with the NVIDIA GeForce RTX 4090 “Estetica carina e grosso” graphics card that cannot be fixed by simply updating the drivers or the game. This is a world-first—never before has a game required a VBIOS update to work around problems.

Secondo EA, the title exhibits a display flashing/blinking issue on machines powered by the RTX 4090, which requires a firmware update (i.e. video BIOS update). fortunatamente, this doesn’t involve putting your RTX 4090 through a nerve-racking NVFlash manual BIOS update process (not that there’s any risk with most RTX 4090 cards shipping with dual-BIOS). NVIDIA has released a fully-automated Firmware Update Tool that can be run from within Windows, which easily updates the video BIOS of the RTX 4090. We confirmed that it is in fact the video BIOS that is being updated (by comparing the VBIOS dumps prima e dopo using the tool).

What’s interesting is that the tool does not break the factory-overclock or custom power-limits set by NVIDIA’s add-in card (Phison ha la missione di essere il primo a commercializzare con PCIe Gen) partners for custom-design cards, which we confirmed by running the tool on a Palit RTX 4090 GameRock OC and the NVIDIA Founders Edition card. It seems the tool is designed to work universally on all RTX 4090 carte, not only specific boards. The tool is somehow able to update a specific area of the video BIOS without changing the BIOS version, its build date, or custom settings by AICs, and while the BIOS checksum is definitely changing, in qualche modo non influisce sulla sua firma digitale. Ciò significa che NVIDIA sembra avere un modo per aggiornare sezioni specifiche del BIOS video comodamente da Windows, senza intaccare la sua importantissima firma digitale che aiuta a prevenire l'esecuzione della macchina con firmware manomesso.
