One of the hot topics among console gamers these days is ‘optimization’. This is because games that are disappointing with optimization levels that fall short of expectations are appearing one following another. For example, the fact that the highly anticipated ‘Starfield’, which started pre-sale on the 12th, operates at 30 frames per second on the Xbox console, caused dissatisfaction. ‘Final Fantasy 16’, released on the 22nd, is known to fail to perfectly maintain 60 frames per second even though the resolution drops to a minimum of 720P in performance mode. Final Fantasy 16. Source = Square Enix Frames Per Second is a number that indicates how many images (frames) are displayed in one second. The higher it is, the softer the screen feels. In the past, 30fps was common in console games. However, since the introduction of so-called 9th generation console game consoles such as PlayStation 5 and Xbox Series X, games that support 60 frames or more have increased significantly. accept it as a step back Last year, ‘Gotham Knight’ and ‘Flag Tale: Requiem’ were criticized for supporting only 30 frame mode at the time of release. ‘Flag Tail: Requiem’ later accepted criticism and provided an additional 60 frame mode as a patch. ‘Flag Tail: Requiem’, which was disappointing by only supporting a 30 frame mode at the time of release.

Digital Foundry, a game technology analysis media, said, “Final Fantasy 16 raises more questions regarding the current generation 60 frame game.” This means that 60 fps is not always achievable,” he pointed out. Digital Foundry’s Richard Leadbetter already predicted last year that “as the number of titles dedicated to the current generation increases, you should expect that 60 fps supported games will gradually decrease.” Unlike before, when games were developed considering compatibility with previous generation consoles, it is explained that as more games try to raise the graphic quality to match the current generation consoles, it will be difficult to achieve 60 frames. In this situation, 40 is attracting attention as one of the alternatives. frame mode. The 40fps mode was first introduced by Insomniac Games in ‘Ratchet & Clank: Rift Apart’ and has since spread around Sony’s PlayStation Studio games. ‘Marvel Spider-Man Remastered’, ‘Horizon Forbidden West’, and ‘God of War Ragnarok’ all support 40 frame mode. ‘Ratchet & Clank: Rift Apart’, which introduced 40 frame mode for the first time.

If you simply look at the frame rate, it looks like it has increased by 10 frames compared to 30 frames, but the actual effect is much greater. This is because the frame time, which represents the interval between frames, is 25 milliseconds, which is the middle value of 16.6 milliseconds (ms) for 60 frames and 33.3 milliseconds for 30 frames. That is the penetration rate of 120Hz displays. This is because the 40 frame mode is only available on 120Hz displays. Unfortunately, the 40 frame mode is only available on high-end TVs or gaming monitors that support a 120Hz refresh rate. The photo is LG Electronics’ OLED TV.

A refresh rate of 60 Hz means that the screen flickers 60 times per second. If you want to display 60 frames per second on a 60Hz display, you can update the frame according to when the screen flickers once. For 30 frames, you only need to update the frame once every time the screen flickers twice. However, since 40 frames are neatly divided into integers and do not fall apart, the interval inevitably varies from frame to frame. If the interval between frames is not constant, the screen may feel unnaturally cut off or vibrate. On the other hand, for a 120Hz display, 40 frames can be updated at regular intervals. This is because it only needs to update the frame once when the screen flickers three times. It’s also why 40fps mode didn’t exist until 120Hz displays came along. The fact that 40fps mode is only available on 120Hz displays suggests that 40fps mode is a feature only available to gamers who own some high-end TVs or high refresh rate monitors. means that Omdia, a market research firm, predicted shipments of TV panels supporting a high refresh rate of 120Hz or higher at 25 million units last year. This is only 12% of global TV shipments, which were 203.25 million units last year. Donga.com IT expert Kwon Taek-gyeong, reporter tk@itdonga.com
