Over the past decade, real-time graphics rendering has faced an increasingly difficult challenge: delivering higher visual fidelity while maintaining playable performance. Technologies like ray tracing and path tracing dramatically improve realism, but they also push GPUs to their limits. To address this problem, GPU vendors (NVIDIA, AMD, and Intel) have introduced neural rendering and image reconstruction technologies designed to not only improve performance — via temporal upscaling — but also improve visual smoothness — via frame generation/interpolation — and denoising of ray/path-traced effects, via machine learning-powered denoising. Three major technology suites dominate this space today: What started as simple spatial […]
