Last month Nvidia announced it was bringing “basic ray tracing” to some of its non-RTX GPUs in April, and that update is now live on Nvidia’s website. You can download the new graphics driver from Nvidia in order to enable this functionality, but keep in mind that “basic RT” effects are limited to just Pascal GPUs, and the GTX variants of its Turing cards, such as the GTX 1660 Ti and GTX 1660 (as well as laptops with equivalent GPUs). People who own RTX cards don’t get much out of this update, other than the ability to say, “welcome to the party” to people with lesser GPUs in the comment sections of websites such as this.
