With the announcement of the new Snapdragon 8 Gen 2 chipset, Ray Tracing was mentioned a lot by Qualcomm and its potential for immersive mobile gaming. To see how it really works, OPPO just released a video about its Mobile Ray Tracing Demo Gameplay.
Apparently, OPPO has been working with Qualcomm on real-time hardware-accelerated ray tracing for some time. To simulate a real 3A mobile game, OPPO made a first-person shooter game scene called “Camp Guard” with over 2,000 physical models, 800,000 triangles, and close to 100 textures. You can check out the gameplay video below.
In the video, the Camp Guard mobile game ran at 720p@60fps for half an hour on a room-temperature device powered by the Snapdragon 8 Gen 2. The lights and shades of the characters and objects in the game react realistically according to the model’s movement and the player’s camera angle, just like from PCs and consoles.
To make it happen, PhysRay Engine 2.0 drivers were optimized to render different Ray Tracing effects and textures smoothly. To improve the graphics and handle the power consumption at the same time, Qualcomm's Variable Rate Sharing (VRS) technology was involved to sure the PhysRay Engine 2.0 runs efficiently.
By the way, the PhysRay Engine is a fully open Ray Tracing solution for its global developers and creators. It's also said that game developers can add OPPO’s mobile ray tracing pipeline directly without making drastic changes and being restricted.
