Even if you have the most powerful gaming mobile on the market, you have to accept that some games do not display at the highest resolution or with the most realistic graphics; In the mobile phone industry, there are significant limits in terms of how much power can be used, after all.
How Super Resolution Will Improve Graphics
Qualcomm has just presented what could be the solution that fans have been waiting for; his name is Snapdragon game super resolution (GSR), and it is the implementation of a technology that is already successful in the field of computers and video game consoles.
The big problem with having such realistic video games is that current hardware is not capable of running them at maximum resolution and smoothly; some sacrifices we have to make, either by lowering the resolution, or by accepting lower frames per second. To avoid this, the two main graphics card manufacturers, Nvidia and AMD, have offered Super Resolution technologies for years, which allow you to obtain all the advantages with the minimum possible sacrifice.
Qualcomm promises to be able to upscale 540p games to 1080p losslessly
Super Resolution consists of running the game in a lower resolution than the native resolution of our screen; Typically, this means the game is blurry because the screen needs to magnify a small image. The innovation lies in the use advanced algorithms to enlarge the image at native resolution without losing detail that would appear in native resolution. This way, the game is smoother because the hardware has to render fewer pixels.
Qualcomm’s implementation brings this technology to the mobile sector, and this is where it can shine the most due to the limited power of mobile chips. If all goes well, we might get games with better graphics and running better without the need to upgrade to a more powerful mobile.
The key to making this work well, of course, is the image magnification algorithms. Basic and typical bilinear interpolation magnification gives fuzzy results. Qualcomm claims Snapdragon GSR is capable of upscaling a 540p resolution image to 1080p while maintaining quality graphics, increasing the frame rate per second at which the game plays and thus providing a smoother experience.
La tecnología de Qualcomm también puede pasar juegos a resolución 4K
El Androide Libre
Otro detalle importante es que es muy rápido, ya que hace sólo una pasada sobre la imagen. Qualcomm afirma que los juegos que ahora van a 30 frames por segundo se pueden jugar a más de 60 fps, aprovechando las nuevas pantallas más rápidas, y que los juegos que ahora van a 1080p se podrán ejecutar a 4K.
Ahora bien, no podemos compararlo con lo que es capaz de hacer un ordenador. Qualcomm aclara que otras técnicas pueden ofrecer una calidad de imagen superior, pero que requieren de hardware específico como una tarjeta gráfica de una marca concreta.
En cambio, Snapdragon GSR es compatible con la mayoría de las GPUs actuales del mercado con chips Snapdragon, por lo que sólo es necesario que el creador del juego añada la compatibilidad con esta tecnología para aprovecharla. Qualcomm espera que los primeros juegos compatibles lleguen este mismo año, y títulos como Call of Duty Warzone Mobile, Return to Empire y Farming Simulator 2023 ya han anunciado que lo serán con una actualización.
