Nvidia Brings Ray Tracing to GTX Cards - But There's a Catch

Nvidia to enable ray tracing for non-RTX GPUs

Control Gets New Footage From GDC 2019 Featuring Impressive Ray Tracing Effects

As NVIDIA noted, GeForce GTX gamers will have an opportunity to use ray tracing at lower RT quality settings and resolutions, while GeForce RTX users will experience up to 2-3x faster performance.

We'll just have to wait and see if this encourages more game developers to support ray tracing, which is what Nvidia is doubtlessly hoping for.

Unity announced that it is working closely with NVIDIA to offer production-focused early-access for real-time ray tracing in the High Definition Render Pipeline (HDRP) starting, with an optimised preview solution available for customers in the second half of 2019.

Nvidia has announced that Pascal GPUs beginning with the GTX 1060 all the way up to the Titan XP will support ray tracing following the release of an official driver update due out in April.

"Until Nvidia RTX, real-time ray tracing was perpetually on the horizon". "The integration of real-time ray tracing by the two dominant game engines illustrates the game industry's belief that real-time ray tracing is the future of gaming graphics". That's support for Microsoft's DXR API which will enable real-time raytracing capabilities in existing and upcoming gaming titles.

With this driver, GeForce GTX GPUs will execute ray traced effects on shader cores. Today, the company introduced the GameWorks RTX toolkit in an attempt to encourage developers to incorporate the graphics technology in their games.

Come GDC 2019, NVIDIA is now enabling another feature which was previously locked down to the newly released Turing GPU based graphics cards. "Now millions of developers working in Unity can achieve unbelievable graphics with lightning speed", Nvidia vice president of Professional Visualization Bob Pette said.

GTX cards will be able to handle basic single effects such as shadows or reflections. The classic Quake II game was modified in the open source community to support ray tracing and NVIDIA's engineering team further enhanced it with improved graphics and physics.

It includes the RTX Denoiser SDK that enables real-time ray tracing through techniques that reduce the required ray count and number of samples per pixel.
