How to Guide

Have you bought a Mac Mini or MacBook but don't want to use the thin membrane keyboard or pay for the expensive official keyboards? 

Found a mechanical keyboard you love but noticed it doesn’t come with a dedicated Mac layout? No worries! As long as it’s a keyboard, it can generally be used with a Mac — you just need a few settings adjustments to make everything run smoothly.

How to Set Up Windows Layout Function Keys on a Mac

 | Open the Settings menu, select "Keyboard," and then click "Keyboard Shortcuts."

 | Scroll down to find "Modifier Keys" and choose the name of the keyboard you want to modify.

 | Click "Done" and test if everything works correctly.

When connecting an external keyboard to a Mac for the first time, the Command and Option keys may behave differently, so you’ll need to remap them.

The DF98 mechanical keyboards also support key customization, allowing seamless switching between Windows and Mac systems, truly delivering a one-key dual-system experience!

A Must-Read for Mac Users: How to Remap a Regular Keyboard to Mac Layout

Vertical GPU mounting certainly looks more aesthetically pleasing in a build, but since it requires the use of a riser cable, some worry that it might prevent the graphics card from performing at its best. So, how much performance loss does it actually cause? Will it significantly impact gaming performance?

In this test, we also examined performance differences when using PCIe 3.0, PCIe 4.0, and PCIe 5.0 riser cables.

Using the 3DMark Time Spy benchmark, the results all fell within the margin of error. Surprisingly, the theoretical scores with PCIe 3.0, PCIe 4.0, and PCIe 5.0 riser cables were even slightly higher than when the GPU was plugged directly into the motherboard.

Rather than synthetic benchmarks, gamers care more about real-world performance in games. So we tested three currently popular games using their built-in benchmarking tools.

 showed that using a PCIe 5.0 riser cable yielded similar average FPS to direct motherboard installation. However, using PCIe 4.0 and PCIe 3.0 riser cables resulted in a 12% and 32% FPS drop respectively.

 uses the latest Unreal Engine 5, which places high demands on bandwidth, making lower-speed riser cables a bottleneck.

, PCIe 4.0 and PCIe 3.0 riser cables resulted in 4% and 12% performance loss respectively, which is less severe than in 

, only the PCIe 3.0 riser cable showed about 5% performance loss, and the overall gameplay experience wasn’t noticeably affected.

Is It Worth Using a Riser Cable for Vertical GPU Mounting?

Based on the benchmark and game test results, if you want to squeeze out every last bit of performance from your GPU, plugging it directly into the motherboard is the best choice.

However, if you prioritize aesthetics and are willing to sacrifice a bit of gaming performance, make sure to use a PCIe 4.0 or higher riser cable to minimize performance loss.

Test Setup





CPU: AMD Ryzen 7 9800X3D



Motherboard: ASUS PRIME X670E-PRO



Graphics Card: GIGABYTE AORUS GeForce RTX 5090 MASTER 32G







Benchmark Results

Using the 3DMark Time Spy benchmark, the results all fell within the margin of error. Surprisingly, the theoretical scores with PCIe 3.0, PCIe 4.0, and PCIe 5.0 riser cables were even slightly higher than when the GPU was plugged directly into the motherboard.







Game Test Results

Rather than synthetic benchmarks, gamers care more about real-world performance in games. So we tested three currently popular games using their built-in benchmarking tools.



Game Test: Black Myth: Wukong

The results for Black Myth: Wukong showed that using a PCIe 5.0 riser cable yielded similar average FPS to direct motherboard installation. However, using PCIe 4.0 and PCIe 3.0 riser cables resulted in a 12% and 32% FPS drop respectively.



The likely reason is that Black Myth: Wukong uses the latest Unreal Engine 5, which places high demands on bandwidth, making lower-speed riser cables a bottleneck.







Game Test: Forza Horizon 5

In Forza Horizon 5, PCIe 4.0 and PCIe 3.0 riser cables resulted in 4% and 12% performance loss respectively, which is less severe than in Black Myth: Wukong.







Game Test: Red Dead Redemption II

In Red Dead Redemption 2, only the PCIe 3.0 riser cable showed about 5% performance loss, and the overall gameplay experience wasn’t noticeably affected.

If you're aiming for both aesthetics and performance, it's recommended to use a PCIe 4.0 or higher riser cable. However, if performance is your top priority, installing the GPU directly is the best choice.

Before understanding the differences between USB and WiFi 2.4G, it's important to know what 2.4G is.

2.4G refers to the 2.4 GHz wireless frequency band, which is a commonly used range for wireless communication. It's mainly used in WiFi, Bluetooth, wireless mice and keyboards, wireless headsets, and other devices.

While USB 2.4GHz has a dedicated connection channel with lower chances of interference, having too many USB 2.4G devices nearby can still cause interference.





Before understanding the differences between USB and WiFi 2.4G, it's important to know what 2.4G is.

2.4G refers to the 2.4 GHz wireless frequency band, which is a commonly used range for wireless communication. It's mainly used in WiFi, Bluetooth, wireless mice and keyboards, wireless headsets, and other devices.



What are the characteristics of 2.4GHz?







Strong signal penetration: Compared to 5GHz, 2.4G signals can better penetrate walls and obstacles, making it more suitable for long-distance transmission.



Longer transmission range: Under the same power, 2.4G can reach farther distances, which is ideal for larger spaces.



Widespread usage: Many wireless technologies like Bluetooth and WiFi operate on the 2.4G band, so interference is something to watch out for.



Differences Between USB 2.4GHz and WiFi 2.4GHz

Difference 1｜Different Uses







USB 2.4GHz: Mainly used for wireless connections to devices like mice, keyboards, and headsets. It uses the 2.4GHz band for low-latency, high-stability wireless transmission.



WiFi 2.4GHz: Used for internet connectivity. It also uses the 2.4GHz band to provide wireless networking over longer distances, though it's more prone to interference.







Difference 2｜Different Communication Technologies







USB 2.4GHz: Uses RF (radio frequency) wireless technology to create a dedicated channel between the USB receiver and the device, resulting in a more stable connection that’s less affected by WiFi interference.



WiFi 2.4GHz: Supports multiple device connections, but too many devices on the same frequency can cause slower speeds and less stability.







Difference 3｜Connection Range and Interference







USB 2.4GHz: Typically supports a range of about 5–10 meters. Since it uses a dedicated channel, interference is relatively low, making it great for gaming and other demanding uses.



WiFi 2.4GHz: Can reach over 30 meters, but is easily affected by other 2.4G devices, which can weaken the signal and reduce internet speed.







USB 2.4GHz vs. WiFi 2.4GHz Comparison Table







While USB 2.4GHz has a dedicated connection channel with lower chances of interference, having too many USB 2.4G devices nearby can still cause interference.

2.4G is widely used in everyday life, but it's mainly applied in USB and WiFi connections—here’s everything you need to know in one go!
