Nvidia’s GeForce RTX 5090, 5080, and 5070 Ti are among the most in-demand GPUs immediately, however when you suppose they’ll make it easier to play your Steam account’s again catalog at blistering FPS, chances are you’ll be higher sticking together with your previous RTX 30- or 40-series. Nvidia dropped its hardware-accelerated physics system assist for among the finest video games from the early 2010s. It’s simply one other means fashionable {hardware} builders are failing to protect previous titles of their prime.
Earlier this week, Nvidia confirmed in its official boards that “32-bit CUDA functions are deprecated on GeForce RTX 50 sequence GPUS.” The corporate’s assist web page for its “Help plan for 32-bit CUDA” notes that some 32-bit capabilities have been faraway from CUDA 12.0 however doesn’t point out PhysX. Successfully, the 50 sequence playing cards can’t run any recreation with PhysX as builders initially supposed. That’s ironic, contemplating Nvidia initially pushed this tech again within the early 2010s to promote its early GTX vary of GPUs.
PhysX is a GPU-accelerated physics system that enables for extra practical physics simulations in video games with out placing strain on the CPU. This included small particle results like fog or smoke and fabric motion. Nvidia developed it and promoted 32-bit PhysX as a physics engine, although they solely managed to deploy 32-bit PhysX in a couple of dozen video games in engines starting from Unreal to Unity to Gamebryo. These relied on the CUDA cores for GeForce graphics playing cards, which is why it’s so unusual to see the capabilities deprecated now. Fashionable video games depend on a variety of physics methods that don’t rely on CUDA.
Fashionable PC players can really feel the identical sting as AMD patrons from a decade in the past. Customers on the Resetera boards compiled a listing of all video games that received’t work with GPU-accelerated PhysX, together with classics like Borderlands 2, Mirror’s Edge, Batman: Arkham Metropolis, Metro 2033, Metro Final Mild, and Murderer’s Creed IV: Black Flag. These video games could also be playable with the physics enabled, however you’ll undergo from huge framerate drops. Gizmodo examined some video games and located that efficiency influence could be vital.
The Nvidia GeForce RTX 5090 can push a large variety of frames. As an experiment, I loaded up Deep Rock Galactic and pushed sufficient settings to realize over 800 FPS with 4x body gen. It’s foolish and pointless, however in some ways, so is any FPS rely above 240 (particularly when there’s little level in proudly owning a show above 240 Hz refresh charges).
However examine that to a recreation like Batman: Arkham Metropolis. Rocksteady launched its semi-open world Darkish Knight simulator in 2011, and in some ways, it’s a contemporary basic. Nonetheless, you received’t discover it on Microsoft’s Recreation Move or some other fashionable system besides the Nintendo Change. One of the simplest ways to play it’s on PC, or it might be when you’re utilizing a non-50-series RTX graphics card. I loaded it up on a system with an Nvidia RTX 5070 Ti, and whenever you attempt to allow hardware-accelerated physics in settings, you’ll obtain a word studying, “Your {hardware} doesn’t assist Nvidia {Hardware} Accelerated PhysX. Efficiency will likely be diminished with out devoted {hardware}.”

The in-game benchmark exhibits that with the {hardware} accelerated physics setting enabled on the RTX 5070 Ti, I noticed successful of 65 common FPS in comparison with the setting off, from 164 to 99. The distinction is putting. Within the part the place you battle Mr. Freeze, ice crystals now not bathe the ground as they do with the setting enabled. Smoke now not swimming pools on the bottom, and banners now not flutter within the breeze. These are nonetheless playable framerates, however the CPU should do much more work than it ought to to deal with the physics results, resulting in stuttering and dips that make it a ache to play. My PC included an Intel Core Extremely 9 285K, which—whereas notoriously not as succesful because the 14th-gen high-end Intel chip—could also be higher-end than players who angle towards the mid-range RTX GPUS. I think about some gamers might expertise even worse framerates than I did when making an attempt to drive PhysX to work.
In different video games, like Borderlands 2, the sport merely refuses to permit the PhysX choice. As one Reddit consumer discovered, you possibly can drive it by modifying the sport information, however that may lead to horrible framerate drops. It’s not what the sport makers supposed. The most suitable choice is to plug a separate, older GeForce GPU into the system and run 32-bit PhysX video games solely on that card.
When gaming console makers transfer on, publishers are too eager to neglect about video games from yesteryear. PC gaming is the place most individuals land in the event that they need to attempt to become older titles working, however even then, it’s by no means simple. {Hardware} has to alter, sure, however there’s some legacy software program that ought to stay enabled for the sake of recreation preservation. With its newest RTX 50-series playing cards, Nvidia has did not protect video games in a means that might assist them run as properly immediately as they did again then.
Once we see Nvidia deprecating its personal {hardware} capabilities, hurting video games which can be little greater than a decade previous, we’re reminded simply how tough a activity is recreation preservation. There’s solely a lot firms like GOG can do to make video games run as they have been supposed. Mirror’s Edge used PhysX to create extra thrilling moments, corresponding to in its helicopter chase scene. Batman: Arkham Metropolis used it for the sake of ambiance for its most memorable fights and sections. You might want an RTX 50-series card to get multi-frame gen and over 200 FPS on Cyberpunk 2077 with ray tracing, however you’ll need a 40-series card if you wish to play probably the most stunning video games from 2011.
