Nvidia RTX Expertise Now Working In Some Basic PC Video games
Valve’s basic Portal was not too long ago re-released on Steam with some very fancy new visuals, together with ray-tracing and DLSS help. That was nice information for Portal followers, nevertheless it’s additionally nice information for followers of all types of outdated PC video games.
Earlier than we go any additional, I’ll clarify the tech we’re speaking about. RTX is the identify given to a set of applied sciences utilized by graphics card firm Nvidia that makes use of “ray tracing and AI applied sciences” to, very merely, make PC video games look unbelievable. Right here’s a trailer for Portal With RTX, the re-release of the sport made with this tech, displaying the enhancements made to a sport that the majority of us keep in mind wanting very 2007:
Now, the factor with RTX is that whereas on this case (and with Quake and Minecraft) it needed to be put into the sport by builders, Nvidia are additionally releasing a model of the tech with modders in thoughts. It’s known as RTX Remix:
With RTX Remix, the sport runs within the background and we exchange the outdated rendering APIs and methods with RTX Remix’s 64-bit Vulkan renderer. This allows the addition of ray-tracing to basic video games and all of it updates in real-time as lights and objects transfer. Mild will be forged from behind the participant, or from one other room, and in Portal with RTX, gentle even travels via portals. Glass refracts gentle, surfaces replicate element based mostly on their glossiness, reflections will be forged into the scene from behind the participant, objects can self-reflect, and oblique gentle from off-screen illuminates and impacts what you see.
In comparison with Quake II RTX and Minecraft with RTX, the path-traced ray tracing launched by RTX Remix is much more superior, bouncing gentle 4 occasions as an alternative of as soon as, enhancing high quality, immersion, and the simulation of real-world gentle. Moreover, we’ve additionally launched a number of new ray tracing methods that additional enhance high quality whereas additionally being extra performant.
Nvidia says that RTX Remix is “a modding platform” that can enable “modders of all skill ranges to carry ray tracing and NVIDIA applied sciences to basic video games”. Given it’s not out till 2023 I used to be anticipating we have been nonetheless months away from seeing what advantages it may carry to older video games, however nope!
Modders like LordVulcan have discovered you’ll be able to add RTX juice to some basic titles, proper now, and normally it’s accomplished simply by…dropping some recordsdata from one folder to a different in your laborious drive and enabling some developer stuff within the console. That’s it. And it’s engaged on video games like SWAT 4 and the unique Max Payne.
G/O Media could get a fee
Whereas the outcomes aren’t good, at least compared to the professional jobs done over months on games like Minecraft, they nonetheless look implausible! Right here’s Max Payne, for instance, courtesy of Alex Coulter:
That lighting. These shadows. That is magic.
Right here’s some footage of SWAT 4 taken by EiermannTelevision, which was launched in 2005 and most positively didn’t appear like this on the time:
And right here’s Half-Life 1, together with somewhat explainer on the way it was accomplished:
None of these examples are good, nevertheless it’s unbelievable they work this nicely given how fast their implementation was. That is going to be so good when the precise RTX Remix is launched in 2023, however till then it’s going to be cool seeing what different basic titles this slapdash workaround is suitable with!
