Stay In The Light Rtx
Stay in the Lite is an indie game that requires ray tracing
Ray tracing is perhaps one of the hottest and most controversial topics in gaming graphics correct now. Nvidia will tell you lot ray tracing is the time to come, and that's why information technology built support into its RTX graphics cards. AMD has been less enthusiastic, forgoing DirectX Raytracing (DXR) API support for its current generation GPUs.
Merely for indie developer Richard Cowgill, he's going all-in on DXR for his next game, Stay in the Light, which launched on Steam Early on Access today. I spoke with Richard near Stay in the Light, what he thinks about ray tracing, and the future of graphics. I besides got to try the game out for myself.
Cowgill has been working in the games industry since 2000. He started with the Desert Gainsay modernistic for Battlefield 1942, then worked with the get-go ii Borderlands games at Gearbox, as well as Battlefield 2. Then he left the big game developers behind and went independent a few years ago. Stay in the Light is his chance to get his feet wet with DXR, and it started with Nvidia'due south release of DXR drivers for GTX cards.
At the fourth dimension, Cowgill was using a GTX 1080 Ti, so those drivers allowed him to commencement working with Unreal Engine's ray tracing support. He started work on a procedurally generated horror game that would brand lighting and reflections a major part of the game. Initial epitome in hand, he went to Reddit to enquire RTX owners to requite it a shot and provide some feedback on performance, which in plow defenseless the middle of Nvidia's Indie Spotlight grouping (opens in new tab). Now, he'southward sporting a GeForce RTX 2080 Ti and continues to iterate on his game idea.
You can encounter the gears turning at Nvidia. "Hey, this game requires DXR—which currently means only GeForce RTX or GTX ten/16-serial cards piece of work. Perhaps this will help become people excited near ray tracing!" It might, but perhaps more importantly information technology shows how quickly things can exist put together with mod evolution tools.
In less than ii months, Cowgill has gone from nothing to at to the lowest degree the basic outline of the game he wants to brand. A lot of the heavy lifting comes via Unreal Engine, obviously, but that combined with ray tracing means he doesn't have to put a lot of actress fourth dimension and endeavor into figuring out lighting, shadows, and reflections. The game engine handles that in the groundwork. Information technology's however a piece of work in progress, but here's what Stay in the Light looks like right now, running on an RTX 2080 Ti:
Again, this is Early Access, and there are bugs and other mechanics that seem broken (or at least, I haven't figured them out). You're running—walking, really—around in a dungeon that floats in the sky, picking up treasure and trying to notice the exit to the adjacent level, all before some big hairy ogre named Him nabs you. He doesn't similar light, in theory, but he as well teleports around and often I'll only meet a blue sparkle. Information technology'south yet plenty to put me on border, and I may have yelped a little at the end of the in a higher place video when I died. But there's not a lot of game here just even so.
On the technical side of things, I asked Cowgill most how difficult it would exist to guess the lighting and reflections without using DXR. Theoretically, it can be done (shadows should be fine), only it would be less accurate, and it potentially wouldn't run faster. Doing the second viewport for the mirror to accurately handle reflections is particularly difficult—and with procedurally generated levels, there's no way to 'bake' the lighting in advance. Everything has to be calculated at runtime.
The electric current build of Stay in the Light feels more similar a tech demo, merely hopefully that changes over time. I've likewise seen performance bog downwardly pretty hard even with the 2080 Ti, and in that location'due south certainly room for more than optimizations as the development progresses. Not surprisingly, if you lot try to launch the game on an AMD GPU, it simply fails. I've asked AMD most DXR enabled drivers for their existing cards in the past, and the official response is:
"AMD is actively working in shut collaboration with Microsoft to enable DXR support. Nosotros volition provide more than item when nosotros're closer to releasing a productized solution."
With Stay in the Calorie-free as the most recent DXR-enabled game (fifty-fifty if information technology's still very early correct now), that brings the total number of publicly bachelor ray tracing games to half dozen (Battlefield 5, Metro Exodus, Shadow of the Tomb Raider, Justice, Convulse 2 RTX, and Stay in the Light), with Wolfenstein: Youngblood set to join the group on July 26, and several more slated to launch later this year. I'thousand yet looking for ray tracing's killer app, however, and while it's cool to run into what Cowgill was able to achieve in just a few months of work, information technology isn't going to make people run out and buy an RTX card. And that may non even be necessary, every bit Cowgill hopes to get the last release to a point where it will run okay on a GTX 1060.
By the fourth dimension the game leaves Early Admission, maybe AMD will accept DXR-enabled drivers—or mayhap fifty-fifty a Navi GPU that has hardware support for ray tracing. But after feeling more than a piffling underwhelmed by the utilise of ray tracing in Battlefield 5, Metro Exodus, and Shadow of the Tomb Raider, I'1000 more than optimistic for what the indie scene can practice with the technology. Making it a core function of the gameplay and experimenting in means that big publishers don't could exist just what DXR needs. And I withal believe at some point, perhaps five-x years from now, we'll be looking dorsum at the first generation of ray tracing hardware and recognizing it as the impetus that enabled time to come games and graphics to improve.
