After a driver update on my Surface Pro 8, I discovered that it finally supports VRR (Variable Refresh Rate). This means the display’s refresh rate is no longer fixed at 60/120 Hz, but dynamically adjusts according to the rendering speed of the content. This brings lower latency and provides smoother visuals when game frame ratesContinue reading “Streaming with VRR (Variable Refresh Rate) on Intel Integrated Graphics”

Google Lens was originally a very convenient feature that could be used for reverse image search, translating images, and OCR to recognize text in pictures. However, for such a practical feature, Google has chosen to integrate it into Chrome in the worst possible way: as soon as a logged-in user clicks the Omnibox (address bar),Continue reading “Remove Google Lens from Chrome”

Recently, while using Moonlight + Sunshine for game streaming on my Surface Pro 8 (PC wired to the router, Surface using Wi-Fi), even with full Wi-Fi signal strength, I experienced occasional audio crackling and video stuttering. Running PingPlotter in the background for network testing revealed that every 10 minutes, latency would spike for a fewContinue reading “Fixing Intel Wi-Fi Stuttering on Latest Driver (Global BG Scan Blocking)”

The long-awaited Nintendo Switch 2 is finally in my hands. The Switch 2 introduces a new mouse mode, where you simply hold the Joy-Con 2 on a surface like a mouse, and a cursor appears on the screen, similar to the Lenovo Legion Go released two years ago. However, my first impression of the SwitchContinue reading “Switch 2 Mouse Mode Input Latency Test”

Perhaps because Intel realized their new products weren’t selling, the Core Ultra 200S series CPUs have seen significant price cuts. I took the opportunity to build a new PC with an Intel Core Ultra 7 265K, temporarily using the integrated graphics. While the Core Ultra 200S isn’t great for gaming performance (especially online games), forContinue reading “Fixing Ultra 7 265K’s Frequent Stuttering”

I recently got a new phone and installed Smart AutoClicker to automatically click the skip button while idling in single-player games. However, on the accessibility settings page, I couldn’t grant the clicker permission. I tried using an adb command (adb shell settings put secure enabled_accessibility_services …), but it still didn’t work. After checking logcat, IContinue reading “Enables Accessibility Features for Sideloaded Apps on Android 15”

BBR is a TCP congestion control algorithm developed by Google. It improves upon the shortcomings of traditional congestion control algorithms (like CUBIC), which reduce speed upon packet loss, significantly enhancing bandwidth utilization in high packet loss environments. It’s important to note that congestion control algorithms manage the packet sending rate. For example, if a GoogleContinue reading “Enable TCP BBR v2 on Linux & Windows 11”

Installing ESXi on an unsupported device is a matter of luck. Unfortunately, I found that my computer’s built-in NIC is a Realtek R8168 — a network card no longer supported by ESXi. In the ESXi 6.x era, we could add the net55-r8168 driver to make ESXi support this NIC, but after ESXi 7.x disabled allContinue reading “ESXi 7.0 + R8168 / R8169 Installation Notes”

Telegram claims to have 5 data centers (DCs), referred to as DC1~5 in Telegram’s code and documentation. Among them, DC1 and DC3 are located in Miami, USA; DC2 and DC4 are in Amsterdam, Netherlands; and DC5 is in Singapore. Each account is associated with a DC upon registration and does not change with the user’sContinue reading “Mysteries of Telegram DC”

Windows 11 has significantly improved the touchscreen experience and added support for native Android emulation, making me want to try a touch-enabled Windows 2-in-1 device again. Coinciding with the release of the Surface Pro 8, this model ditches the 6-year-old thick-bezel design, featuring a 13” 120Hz high-refresh-rate screen and Intel’s most powerful integrated graphics, IrisContinue reading “Optimizing my Surface Pro 8”
