The Need for Speed Unbound game, which went on sale today, revealed a previously hidden bug in the flagship GeForce RTX 4090 video card. And you can’t fix it with a regular video driver update – you have to update the vBIOS firmware graphics of the accelerator. This is probably the first time in history that a game requires a graphics card firmware update to fix any issues.

According to the data Support for electronic arts, flickering may occur in Need for Speed Unbound on systems equipped with GeForce RTX 4090. You can only fix the problem by updating the firmware of the video card itself. Fortunately, this doesn’t require the rather risky process of manually updating the BIOS with NVFlash. NVIDIA has already released a special updater Firmware update toolwhich will do everything automatically. At the same time, updating the video card BIOS can be done in the Windows environment. This is confirmed by TechPowerUp, which has already updated its editorial GeForce RTX 4090.

Curiously, the GeForce RTX 4090 BIOS Auto Update Tool does not factory overclock GPUs or change TDP limit settings for non-reference versions of NVIDIA partner video cards. TechPowerUp resource made sure of this by updating Palit GeForce RTX 4090 GameRock OC and NVIDIA using NVIDIA Firmware Update Tool. GeForce RTX 4090 Founders Edition.

It seems that the update tool is universal for all versions of the GeForce RTX 4090. It somehow updates only a part of the vBIOS code without changing its version, build date and custom manufacturer settings. And while the vBIOS checksum changes dramatically, this process doesn’t change the digital signature of the firmware. It seems that NVIDIA engineers have found a way to update not the entire vBIOS, but only its individual sections, without affecting the digital signature, which prevents the use of unauthorized firmware.
