Different settings for docked / portable Switch modes spotted in Unreal Engine 4
Over the past few weeks, we’ve heard more and more about different modes for Switch when it’s docked and when the device is being played as a standalone unit. That culminated with a
report from Digital Foundry just a couple of days ago. The publication claims that Switch, when in portable mode, runs at 40 percent of the clock-speed of the fully docked device.
Unreal Engine 4 version 4.14 released about a month ago. One developer has now come across some interesting discoveries which lend credence to some of the recent speculation.
A file in Unreal Engine 4’s master branch shows names for Switch, SwitchConsole and SwitchHandheld. As the developer points out, “the SwitchConsole settings are a notch lower than the UE4 defaults used on PC, PS4 and XB1.” It’s thought that the settings “serve as a good starting point to get a PS4/XB1 UE4 game to run acceptably on the Switch.”
One setting – specifically ScreenPercentage – is set at 66 percent and matches up with talk about Switch displaying at 1080p while docked and 720p when being played as a portable (66 percent of 1920 x 1080 is 1280 x 720). However, instead of only reducing the resolution to 720p in handheld mode, the engine also reduces graphical settings.
Unreal Engine 4 is set at “FXAA” in console mode, but changes to “faster FXAA” in handheld mode. It’s also worth mentioning that Switch uses the full Unreal Engine 4 deferred renderer path rather than the “mobile” renderer.
Here’s a look at the settings in case you’re curious:
[Switch DeviceProfile]
+CVars=sg.ViewDistanceQuality=2
+CVars=sg.AntiAliasingQuality=2
+CVars=sg.ShadowQuality=2
+CVars=sg.PostProcessQuality=2
+CVars=sg.TextureQuality=2
+CVars=sg.EffectsQuality=2
+CVars=r.ScreenPercentage=100
[SwitchConsole DeviceProfile]
DeviceType=Switch
BaseProfileName=Switch
[SwitchHandheld DeviceProfile]
DeviceType=Switch
BaseProfileName=Switch
+CVars=sg.ViewDistanceQuality=1
+CVars=sg.AntiAliasingQuality=1
+CVars=sg.ShadowQuality=1
+CVars=sg.PostProcessQuality=1
+CVars=sg.TextureQuality=1
+CVars=sg.EffectsQuality=1
+CVars=r.ScreenPercentage=66
{Low = 0 Medium = 1 High = 2 Epic = 3}
There’s still a lot that’s unclear, but this helps to fill in a piece of the puzzle. Nintendo will hopefully fully explain how Switch works when docked and playing as a handheld during its big unveiling event next month.
Như cái bài phân tích đầu tiên của mình trang trước thì con Switch bạn mình nói mạnh chắc bằng được 1 nửa so với XBO. Nhưng nó cũng nói thêm đấy là do Nin dùng con tegra cấu trúc cũ nên vậy. Còn nếu dùng đời mới pascal thì mạnh hơn và cũng ko kém XBO xa quá mà vẫn là 1 thiết bị di động..
