Earlier this week, Qualcomm introduced the Snapdragon 8 Gen 2 mobile platform to the general public, which will be the hardware basis for future flagship smartphones from various manufacturers. One of the new features is support for hardware accelerated ray tracing in games. Now Oppo has clearly shown how this innovation works in practice.
To demonstrate the capabilities of the Snapdragon 8 Gen 2 chip, Oppo took a full-fledged game scene from the first-person shooter Camp Guard, which includes more than 2,000 physical models, 800,000 triangles and about 100 textures. Oppo and Qualcomm collaborated to test drivers, tweak shaders and create a game scene compiler.
As a result of these activities, the new mobile platform is able to display various ray tracing effects while supporting high frame rates.
The use of Variable Rate Shading technology allows you to make the gameplay smooth. The demonstration of the game scene in 720p resolution at 60 frames per second provides high-precision lighting of objects in the picture and realistic shadow changes.
One of the challenges of ray tracing is how to realistically represent the surface of the water. In the Oppo demo you can see ripples on the water surface, reflections of sunlight and even traces of waves on the ground.
