Atomic heart rtx tech demo download11/4/2023 From an Nvidia tech demo back to in 2019 to an RTX-branded trailer released just last month, this souped-up lighting and reflection tech has been a key piston in propelling the Soviet sci-fi FPS’ hype train. Actual games obviously won't be full of mirrors/shiny surfaces like the demo, but that just shows that RT in next-gen titles is more than possible. Atomic Heart’s long development cycle has provided ample opportunities to show off the power of ray tracing. Aesthetically sure, it's not impressing, it reminds me of the very first glimpse of current generation that KZ:SF gave us, but tech wise it's on a whole new level. So with that being said, this AMD demo is basically full of mirrors, with infinite light bounces back and forth, and it just runs, in real-time. Tech-demo homepage Tech-demo Download (735MB) I tested the demo on a GeForce RTX 3060 Ti + Ryzen 7 5800X. Now reflections, this is where the hardest part starts, this if what puts BF5 or Controls on their knees, it's simply THAT demanding, the only more demanding calculation is a fully ray traced scene, but that's Hollywood stuff made on tens of thousands of CPUs. Shadows require quite moderate processing power, and as shown in CoD:MW, if all RT capabilities will go solely on that aspect, we can bet basically perfect shadows with little to o performance penaty, as a 2080Ti still runs the game at 4K60 or 200-240FPF at FHD. GI is obviously more demanding, as shown in Gears 5 or Crytec's demo, it can as well be a software solution running on shader processors, but moving thise calculations on RT cores greatly increases the performance. Going from left to right, an RT-based audio requires little-to-no processing power, literally.
