Nvidia has made a significant shift in its support for legacy technologies with the announcement that 32-bit implementations of PhysX<\/strong> will no longer be supported on its new RTX 50 series graphics cards<\/strong>. This decision effectively removes 32-bit CUDA application support<\/strong> on the latest GPUs, marking the end of an era for some older games that rely on this technology.<\/p>\n\n\n\n

For gamers who enjoy titles from the 2000s and early 2010s, this change means losing some of the advanced particle and clothing effects<\/strong> that were originally powered by PhysX. Iconic games like Mirror’s Edge, Mafia II<\/strong>, and Batman: Arkham City<\/strong> will be affected, and while there’s a quick workaround, the move has left many wondering about the future of older game performance on modern hardware.<\/p>\n\n\n\n

What Does This Mean for PhysX?<\/h2>\n\n\n\n

PhysX is Nvidia’s physics engine, responsible for creating dynamic, realistic effects like cloth simulation and particle systems in games. When 32-bit CUDA applications were phased out on the RTX 50 series cards<\/strong>, users immediately noticed the effects in classic games that depend on this engine.<\/p>\n\n\n\n

As highlighted on Nvidia\u2019s forums (via PCGamesN<\/strong>), one user encountered issues when trying to run PhysX with their RTX 5090<\/strong>. PhysX attempted to use hardware acceleration through the CPU<\/strong> instead of the GPU, significantly impacting performance. Nvidia staff responded, confirming that the issue stemmed from the deprecation of 32-bit CUDA<\/strong> support on the new RTX 50 series<\/strong> GPUs.<\/p>\n\n\n\n

The performance loss can be seen in some older titles like Borderlands 2<\/strong>, where the implementation of PhysX is used to enhance environmental dynamics, such as adding cloth textures<\/strong> and dust particles<\/strong>. One Reddit user shared their experience, reporting a significant drop in frame rates<\/strong> when trying to run PhysX on their RTX 5090 FE<\/strong> paired with an AMD Ryzen 7 9800X3D<\/strong> processor. The frame rate dipped to around 60 fps<\/strong>, showcasing the impact of this change.<\/p>\n\n\n\n

While turning off PhysX<\/strong> does make the game feel more static and less immersive, it does not render the game unplayable. However, for some games, like Borderlands 2<\/strong>, there currently isn’t an easy way to disable PhysX, forcing users to rely on CPU-based physics acceleration.<\/p>\n\n\n\n

A List of Affected Games<\/h2>\n\n\n\n

A major list of games that rely on 32-bit PhysX support was posted on ResetEra<\/strong>, with several popular titles<\/strong> on the list. These include Metro: Last Light<\/strong>, Assassin’s Creed: Black Flag<\/strong>, and Tom Clancy\u2019s Ghost Recon Advanced Warfighter 2<\/strong>. While the technology had some notable implementations, such as in Batman: Arkham City<\/strong> and Mirror’s Edge<\/strong>, its performance was often criticized. The reliance on Nvidia-only PhysX<\/strong> cards and the significant work required to make it run meant that it was always a niche feature, rather than a standard.<\/p>\n\n\n\n

What Can You Do About It?<\/h2>\n\n\n\n

If you’re one of the lucky few with an RTX 5080<\/strong> or RTX 5090<\/strong>, there are three major ways to work around the lack of 32-bit PhysX support:<\/p>\n\n\n\n

    \n
  1. Use a secondary PhysX-supported card<\/strong>: You can plug in an older Nvidia GPU specifically for PhysX support.<\/li>\n\n\n\n
  2. Turn off PhysX<\/strong>\u00a0in 32-bit games: This might cause the game to feel a bit more static, but it can improve performance.<\/li>\n\n\n\n
  3. Wait for a community solution<\/strong>: Given the backlash, it\u2019s possible that the community may create workarounds to enable support for older games.<\/li>\n<\/ol>\n\n\n\n

    The removal of support for 32-bit applications on Nvidia cards<\/strong> has been a long time coming. While this is one of the bigger losses for gamers who enjoy classic titles with advanced PhysX features, it\u2019s part of a broader trend toward more modern, efficient architectures. Nvidia has been gradually phasing out legacy support as it moves towards more cutting-edge technologies.<\/p>\n\n\n\n

    Despite the transition, the community is often quick to come up with solutions. So, while official support is ending, there\u2019s hope that third-party fixes will surface to keep older games running smoothly on new hardware.<\/p>\n","protected":false},"excerpt":{"rendered":"
