NVIDIA Driver 581.57 Causes AP204 Error in Forza Motorsport and Horizon on RTX 5090

Video card users NVIDIA RTX 5090 encountered a serious problem when launching games Forza Motorsport 6 Apex, Forza Motorsport 7 и Forza Horizon 3After installing the driver GeForce 581.57 (and earlier 581.47) games throw an error AP204 (GPU not compatible), not recognizing the video card. This error makes launching impossible.

As one user noted, downgrading the driver to version 576.88 completely resolves the issue, confirming that it is indeed a matter of incompatibility between new drivers and outdated games. A second user confirmed a similar situation, and NVIDIA representative, Manuel Guzman, reported that the situation is reproduced in laboratory conditions and is already being tested within the company.

However, there's an important caveat: according to an NVIDIA representative, it's unlikely that this bug will be fixed at the driver level. This is because these games are no longer receiving patches, and the verification system GPU in them, most likely, it is rigidly tied to old video card IDs that do not include new models. This creates compatibility issue, which cannot be resolved without the participation of game developers - and such patches are no longer expected.

Thus, the owners RTX 5090 and new drivers may leave you without access to a number of classic Forza titles unless you use older driver versions. A temporary solution is downgrade to 576.88, but it comes with the risk of losing support for new games and patches.
