NVIDIA’s New GeForce RTX 50-Series Cards to Phase Out PhysX Support for 32-Bit Games

NVIDIA has announced that the upcoming GeForce RTX 50-series video cards will no longer support PhysX for 32-bit games. PhysX is a software development kit (SDK) that enables the real-time simulation of specific physics-related objects within games. This technology has been a staple in the gaming industry since its introduction in 2007, enhancing the visual and interactive experiences in numerous prominent titles.

NVIDIA officially revealed this change on its support page at the end of January, stating that the RTX 50-series would no longer support 32-bit CUDA applications. While the initial announcement did not specifically mention PhysX, it became clear that the support for 32-bit applications was deprecated. Reflecting on historical gaming advancements by Physx, one user pointed out on the NVIDIA forum in mid-February that the technology was indeed not functioning on the RTX 50-series cards due to their lack of support for 32-bit CUDA applications. Consequently, an NVIDIA employee confirmed this deprecation, signaling the end of an era for 32-bit PhysX simulations. According to PCGAMESNK,”With the disappearance of PhysX support for the newest generation of video cards, NVIDIA essentially halts the continuing support for simulation technology.”

For gamers and developers in the U.S., this means that the GTX 9, GTX 10, GTX 16, RTX 20, RTX 30, and RTX 40 series cards will maintain support for 32-bit PhysX calculations. The latest RTX 50-series, however, will primarily support games built on 64-bit architectures, which still leverage Physx technology. Games that utilize 64-bit architecture and incorporate PhysX will continue to run seamlessly on the new series. PhysX allows developers to utilize an NVIDIA GPU with CUDA cores to render specific physics aspects of a game in real time. Theoretically, a system equipped with an RTX 5090 or an AMD video card could still play 32-bit games with PhysX technology, but the physics calculations would be handled by the CPU, leading to significant performance drops as noted in various comparison videos below.

Only a handful of major games have implemented PhysX technology, with notable titles including:

• Mirror’s Edge
• Batman: Arkham Asylum
• Metro 2033
• Borderlands 2
• Assassin’s Creed IV: Black Flag.

Additionally, the game utilized the technology for realistic simulations such as dynamic smoke effects and changing cloth materials. Since 2014, there have been no new games developed utilizing 32-bit PhysX, transitioning almost entirely to 64-bit architectures. Recent titles like Project Cars 2, The Witcher 3: Wild Hunt, and Star Citizen have showcased the advancements in PhysX technology, utilizing it for more intricate and realistic physics simulations.

The shift away from 32-bit PhysX support has raised concerns about the future of legacy games and the potential impact on gaming experiences as seen below:

While this transition effectively marks the end of support for legacy 32-bit PhysX games, it also highlights NVIDIA’s focus on advancing 64-bit technologies, ensuring more robust and immersive gaming experiences. For hardcore gamers and enthusiasts who cherish classic titles like Mirror’s Edge and Batman: Arkham Asylum, running these games on modern hardware without the dedicated GPU-accelerated PhysX could be a significant trade-off. The performance hits observed in comparative videos demonstrate the critical role GPU-accelerated simulations did play, enhancing overall game quality and immersion.

If you are looking to archive such a game to play with a future machine, one advise is to get the unaltered, original, or de-drmed version as well as a legal previous generation of NVIDIA hardware with a driver meeting manufacturer’s requirements. Games designed for a 32-bit architecture or no longer officially supported by games’ original publisher could be problematic for gaming in the future.

The technology is intended to use GPU-accelerated calculations.

For PC hardware enthusiasts like me, this move from NVIDIA is a clear shift in the business strategy towards stepping up GPU-accelerated applications for end-users and commercial real-world applications.

The interpreter for the article “NVIDIA officially announced the depreciation in support of and removal of PhysX SDK for 32-bit app” highlighted that Physx was terrific for physically accurate simulations which were harnessed by quite well-known games from before 2014 and up until now physiologically and also NVIDIAs likely strategy can change in the future but as per “development kits being few and very fuera” it indicates the obsolescence of using tech from up to 16 years ago may be endangered.

Conclusion: For gamers worldwide, NVIDIA’s decision to discontinue 32-bit PhysX support on the upcoming RTX 50-series video cards marks a pivotal shift. Players and the gaming industry focusing on enhancing gaming experiences and advancing technology can’t disregard the nostalgic value and visionary role 32-bit games and technologies hold for the industry. As the sector evolves, gaming hardware, and software trends will continue to challenge both developers and consumers. As hard-core faunos and tech junkies we are taking the considerations into not only the future of these games but also their environments. How much decoder available will there be. It’d benefit to think about all these topics and more about education and training on gaming devices. Therefore, there is what responsible gamers and forward-looking organizations can do.
