Key Questions Answered
What improvements does the custom branch of Unreal Engine 4.27 offer?
The custom branch of Unreal Engine 4.27 (NvRTX) enhances Deep Learning Super Sampling (DLSS), RTX Global Illumination (RTXGI), RTX Direct Illumination (RTXDI), and NVIDIA Real-Time Denoisers (NRD). It also improves support for Metahuman hair and increases the number of volumes supported in indirect lighting from 6 to 12.
How does NVIDIA Reflex reduce latency in games?
NVIDIA Reflex aligns game engine work to complete just-in-time for rendering, which eliminates the GPU render queue and reduces CPU back pressure in GPU-bound scenarios. This allows developers to optimize System Latency (click-to-display) effectively, enhancing overall game responsiveness.
What are the key features of the updated RTXGI plugin?
The updated RTXGI plugin doubles the number of volumes supported in the indirect lighting pass, allows developers to adjust screen-space indirect lighting resolution, and supports blending of more than 2 volumes. This enhances the capability to compute multi-bounce indirect lighting without bake times.
