Nvidia announced at this year’s Game Developer’s Conference that it would be bringing DirectX ray tracing (DXR) support to its older Pascal-based graphics cards, so it’s time to buckle in: The drivers are now ready for download. But you may not find the tradeoff between performance and the potentially enhanced quality worth it.The Pascal-generation GTX cards supported include:The Volta-based Titan V and Turing-based GTX 1660 and 1660 TI are also supported. You’ll be able to get the Game Ready driver via GeForce Experience or on GeForce.com, along with some new whizzy demos.The new generation of RTX GPUs based on Nvidia’s Turing architecture arrived last summer, bringing two headline features: processing cores devoted to ray tracing (RT cores) — the same kind of rendering that’s used in almost every 3D animation — and Tensor cores for accelerating the neural network processing which underlies DLSS (Deep Learning Super-Sampling), Nvidia’s new AI-based scaling algorithms which more realistically simulate detail when the graphics processing load starts to punish performance.A less glamorous advance is the concurrent floating-point execution pipeline, which improves overall performance with parallel processing for the myriad calculations which underlie rendering.Ray tracing can make games look better, providing more realistic reflections and shadows, with a lot… Read full this story
