What is gpu scaling
Since its launch on Gamescom in 2018, ray tracing technology has been evolving in the video game industry. However, because this demanding feature puts additional requirements on the graphics performance of your PC, it is used more frequently by games. Developers.
Nvidia is the first to announce the launch of a GPU with RTX (real-time ray tracing) function, and its impressive (but completely irrelevant) 20 series Turing cards are coming.
Thus, a new era of graphics performance began. The 20 series graphics cards are the most powerful graphics cards we have seen, and finally allow real-time rendering of frames using ray tracing effects. However, while this is good news for visual realism, the lack of game compatibility means that users will not be able to enjoy these advanced lighting features for some time.
Fast forward to modern times, and RTX is most often used in industry leading AAA games. Now there are new GPUs available and their performance can not only generate ray tracing effects in real time, but also has a high standard, although it has a great impact on the performance of the game. Although there are now many games that use the RTX function, the big question that we are still asked is: What is ray tracing?
So in the next article, we'll take a deep look at the lighting characteristics that have completely changed the fidelity of graphics, explaining everything you need to know about real-time ray tracing.
So what exactly is ray tracing? Well, in computer graphics, ray tracing is a rendering technique used to create a more realistic representation of lighting and shadows. It focuses on the way light (and shadow) interact with physical objects, creating a deeper level of realism in video games and movies. Ultimately, ray tracing uses an algorithm to trace the path of light rays (such as pixels) and simulate the effect of the light rays when they finally encounter virtual objects.
Now, unlike the scan line rendering method, ray tracing can produce a higher level of visual realism. Allows light to interact with objects and reflect around them in a natural and realistic way. Ray tracing can also produce a host of other optical effects, including reflection, scattering, scattering, and refraction. Additionally, it can also be used to track sound waves in a similar way, allowing game developers to create a more immersive listening experience through reverb and echo.
While this all sounds great to gamers, keep in mind that real-time ray tracing requires a huge price-performance cost. Although ray tracing has been used in film production for some time, we are only now seeing it really appear in modern games, primarily due to its huge performance requirements for PC graphics processing power. If you often watch our YouTube benchmark channel, you will know the huge impact of ray tracing on frame rate output. We tested several different games to understand how ray tracing affects performance, and the results were eye-opening. On average, gamers using the latest 30 or 6000 series GPUs will see a drop in frame rate output of about 30%. For inherently better lighting, the FPS drop is very large. .
Having said that, ray tracing is still in its early stages in video games. Over time, the technology behind ray tracing (and the hardware that powers it) will almost certainly become more advanced.
When RTX first entered the game field, Nvidia made a fuss about how their proprietary card became the only choice for people who wanted to enjoy ray-traced content. However, since then, AMD has released an impressive 6000 series GPU lineup, bringing first-class performance and ray tracing support to red team consumers.
Having said that, there are many different factors to consider when choosing a GPU for ray tracing performance. Here are some of the most important:
Although real-time ray tracing has only been around for a few years, both Sony and Microsoft have promised to provide ray tracing support for their latest game consoles (PlayStation 5 / XBOX Series X). In addition, in an interview with Wired, Cerny specifically stated that there will be "ray tracing acceleration in GPU hardware" on his latest console.
AMD will manufacture parts for the XBOX series X and PS5, and it may use some kind of ray tracing accelerator core, similar to the RT and Tensor cores on Nvidia RTX GPUs. This should provide excellent ray tracing performance for the two consoles separately.
Historically, ray tracing has been used in the film industry for some time, and Monsters University (2013) is the first animated film to use ray tracing for all lighting and shadows. In other words, we have to wait longer to get video game support.
With the advent of RTX support, there are only a few games that truly support ray tracing, and only a few of them have been rated as AAA.
was not much for gamers at the time. Fast forward to Gamescom 2019, a large number of different games have launched ray tracing support, many of which are considered the biggest games of the year. Nvidia also made it clear in the keynote speech that as a company, they will not hinder game developers in any way, allowing them to fully integrate this technology into the latest games.
The following is an up-to-date list of all games that currently provide ray tracing support in one form or another. Keep in mind that not all games on this list will be compatible with AMD graphics cards:
