What Is Ray Tracing? (And What It Means for PC Gaming). What does rtx do

The latest installment of Watch Dogs is to include real-time ray tracing, which should definitely make London look a bit more impressive. Just be sure to take it all down as you run around the streets trying to save the capital and recruiting an army of hackers and resistance fighters.

How to Turn RTX on

You have the best RTX 2060 money can buy, and your RGB setup is as eye-catching as it gets. But what if you are new to all of this and don’t even know how to turn RTX on? Do you have to do anything at all to activate all these fancy new ray tracing effects in your games?

We can help you answer these questions and discuss the setup procedure. We’ll also cover a list of games that support it, and some common misconceptions. Let’s start from the very beginning.

What Is GeForce RTX?

RTX technology is only available with GeForce graphics cards. Here we are talking about the 20 and 30 series GeForce GPUs. You’d be wrong to think you were turning on RTX just by having one of these powerful graphics cards on your PC. You also need to enable one extremely game-changing visual effect in the supported games – real-time ray tracing.

Lighting is one of the most important elements in video games. Until recently, manufacturers have relied on multiple techniques to enhance their appearance. But it was almost impossible to create sufficiently convincing reflections and shadows. The arrival of RTX graphics cards has been hailed as the beginning of a new era. This is the holy grail of computer graphics. It is available to everyone, and what’s more, it works in real time.

Ray tracing is a complex algorithm that computes the behavior of light in a virtual world. When you turn on RTX, you’ll immediately see some significant visual improvements. Reflections on glossy surfaces become more detailed, shadows softer, and the mood of each scene is improved.

However, there is a caveat. Ray tracing in games is a very hardware-intensive process. That’s why Nvidia puts separate RTX cores in its GPUs, and for the best results and optimal performance, you’ll want the best RTX 2080 graphics card or even more powerful. Even with DLSS, another part of Nvidia’s technology designed to improve performance and resolution, enabling ray tracing has a serious impact on performance. FPS drop is always noticeable, so it’s a matter of deciding between performance and graphics.

Which Games Support RTX?

The catalog of RTX-enabled games is growing day by day. Nvidia maintains an up-to-date list of current and upcoming games on its website, and some upcoming titles such as Dying Light 2 have already confirmed ray tracing support.

Gamers began to wonder how to enable ray tracing in Battlefield 5. The 2018 multiplayer FPS was the benchmark for this new technology. This was followed by adventure action control, in which we noticed a greater impact of RTX on the game’s graphics. Set in an office space, Remedy’s Control featured lots of reflective surfaces and lots of translucent glass. Even without RTX, it’s a visually impressive game. But when you turn the effects on, it’s absolutely stunning.

We also cannot forget about the two huge RTX games from 2020, Cyberpunk 2077 and Call of Duty Black Ops: Cold War. Both games relied heavily on ray tracing for an atmospheric effect, especially the former. The inclusion of RTX in Cyberpunk 2077 turns Night City, a huge playground you’ll spend hours on, into a vibrant neon wonderland. You could even say that the game was designed with the RTX in mind, as many streets are filled with glass skyscrapers and giant neon lights.

Several games were created specifically for the ray tracing show. There are also Minecraft RTX and Quake 2 RTX, which are prime examples of how you can improve the atmosphere with better lighting. And since Quake 2 RTX is completely free on Steam, there’s no reason to skip it.

When ray tracing was first announced, it was only available to players with the latest Nvidia graphics cards in their slot machines. Only RTX 20 series cards were able to handle ray tracing and DLSS. While this list included the Nvidia Geforce RTX 2060/2070/2080 and 2080Ti cards, it was not a very extensive list.

The Basics of Ray Tracing

Ray tracing is a technique that works well for illuminating a computer generated scene. The concept is not new; The novelty is having computational power within reach, which enables its effective execution.

Imagine you shoot a beam of light at an object and track it bouncing off the surface, almost as if you are walking into a dark room and pointing a flashlight. Then imagine firing multiple rays, using those that keep coming back (and not coming back) to get an idea of ​​what the scene should look like. For example, rays that did not return were likely blocked by the object, thus creating a shadow. (To think of a concept in the same way as it is to think about how radar works is not far off.)
