Abstract

Real-time rendering techniques developed for computer games combined with the improved algorithms and advanced hardware such as the Nvidia Geforce RTX 3000 series of graphic cards improve the quality of the rendered images in CGI. In this paper, our goal is to test the performance of RTX architecture in Virtual Production and graphics processing. We conducted a series of tests for rendering of a scene in Unreal game engine in a Virtual Production studio. Images are rendered in 4K and output to a network distribution system where the image is broken down into a series of smaller images each rendered onto LED screens. The comparison of render times between two graphics workstations using Nvidia RTX A6000 GPU and Nvidia RTX A3090 GPU show that whilst RTX architecture produces better image quality, the gains might not be worth the additional hardware cost required by the high-end graphic cards. It might also be optimal to split the rendering of the scene across multiple computers.
