Bryan Catanzaro, NVIDIA Vice President of Applied Deep Learning Research gives you the rundown on Ray Reconstruction in his DLSS Tech Talk
Ray Reconstruction enhances every second of gameplay, while also increasing your performance. This free upgrade is the latest in a long list of AI enhancements that make GeForce RTX GPUs the only option for gamers wanting the very best experiences at the highest resolutions, with cutting-edge features like full ray tracing.
Battling the supernatural at the absolute highest settings will demand the very best hardware, and DLSS’ AI acceleration.
To enable DLSS, head to Options > Graphics, scroll to Resolution Upscaling, select DLSS, and then pick the performance mode you want to use under “Render Resolution”. We recommend Quality for 1080p, Balanced or Quality for 1440p, and Performance for 4K.
At 4K, with every setting maxed and full ray tracing enabled, activating Frame Generation, Ray Reconstruction and Super Resolution sees frame rates multiply astronomically. On the GeForce RTX 4090, performance multiplies by 4.1X, enabling owners to play Alan Wake 2 at its very best at over 120 FPS at 4K. And the GeForce RTX 4080 and GeForce RTX 4070 Ti see their performance multiplied by 4.7X, for max setting 4K gameplay at 100 FPS and 80 FPS, respectively.
