Here is how, in Unreal Engine 5, I profile GPU performance of a packaged project to make it as reliable as possible. Usually doing any measurements in the Editor will introduce some overhead so if you want to know the real performance of the actual product it is best to make a standalone package and run the executable file. To get high-level overview of the GPU performance I call 𝗦𝘁𝗮𝘁 𝗚𝗣𝗨 and 𝗦𝘁𝗮𝘁 𝗨𝗡𝗜𝗧 commands from the UE's console. The top part of the attached image shows the result. We get a list of all GPU render passes sorted by execution time, starting with the most expensive one. This list is updated in real-time. To get a detailed GPU snapshot of a single frame run the command called 𝗣𝗿𝗼𝗳𝗶𝗹𝗲𝗚𝗣𝗨 or alternatively use the keys combo 𝗦𝗵𝗶𝗳𝘁+𝗖𝘁𝗿𝗹+[𝗰𝗼𝗺𝗺𝗮]. This will dump to the Log file a much more comprehensive list of timers, as shown in the bottom part of the attached image. The log file can be found under the path: [𝘗𝘈𝘊𝘒𝘈𝘎𝘌𝘋_𝘗𝘙𝘖𝘑𝘌𝘊𝘛]/[𝘗𝘙𝘖𝘑𝘌𝘊𝘛_𝘕𝘈𝘔𝘌]/𝘚𝘢𝘷𝘦𝘥/𝘓𝘰𝘨𝘴 There are two caveats to be mindful of when measuring GPU performance. - The first one is that you need to turn off VSync. You can do that by calling command 𝗿.𝗩𝗦𝘆𝗻𝗰 𝟬. - The second one is that you need to turn off Async Compute. Overall Async Compute is a good thing for performance (saves ~1 ms of frame time) and you want it enabled in the final product, but when measuring individual render passes performance it is best to turn this off with the command 𝗿.𝗥𝗗𝗚.𝗔𝘀𝘆𝗻𝗰𝗖𝗼𝗺𝗽𝘂𝘁𝗲 𝟬. I wrote more extensively on that in one of my previous posts. And finally it is good to measure performance under various resolutions. And that includes both the actual screen/window's resolution and the internal render resolution. As you probably know, Unreal comes with powerful Temporal Super Resolution (TSR) upscaler which not only can anti-alias the image but also upsample it from say 1920x1080 internal resolution to 3840x2160. ------------------------------ To change the resolution of the screen/window you can use the command: 𝗿.𝗦𝗲𝘁𝗥𝗲𝘀 𝗪𝘅𝗛[𝗳/𝘄] - W and H are the screen size in pixels, and f/w determines if you want the 𝗳ullscreen or the 𝘄indowed mode. ------------------------------ The size of the internal resolution is determined as the percentage of the screen's resolution. If you want 50% of pixels on both the width and height use this command: 𝗿.𝗦𝗰𝗿𝗲𝗲𝗻𝗣𝗲𝗿𝗰𝗲𝗻𝘁𝗮𝗴𝗲 𝟱𝟬 ------------------------------ Finally, I often opt to disable dynamic resolution scaling so that I have consistent measurements regardless of the GPU workload. You can disable dynamic resolution scaling with the command: 𝗿.𝗗𝘆𝗻𝗮𝗺𝗶𝗰𝗥𝗲𝘀.𝗢𝗽𝗲𝗿𝗮𝘁𝗶𝗼𝗻𝗠𝗼𝗱𝗲 𝟬 ------------------------------ As an example, calling: 𝗿.𝗦𝗲𝘁𝗥𝗲𝘀 𝟯𝟴𝟰𝟬𝘅𝟮𝟭𝟲𝟬𝗳 𝗿.𝗦𝗰𝗿𝗲𝗲𝗻𝗣𝗲𝗿𝗰𝗲𝗻𝘁𝗮𝗴𝗲 𝟱𝟬 will result in the fullscreen mode at 3840x2160 resolution, and 1920x1080 internal rendering resolution. .

📦 Understanding Network Cables and Their Applications Selecting the appropriate Ethernet cable is critical to achieving optimal network performance, stability, and scalability. Below is a breakdown of commonly used network cable categories and their respective use cases:   1. Category 5 (Cat5) Specifications: 100 MHz / Up to 100 Mbps Designed for basic networking needs such as connecting IP cameras or simple internet access. Suitable for small networks with minimal bandwidth requirements. Note: This standard is now largely obsolete in most modern setups.   2. Category 5e (Cat5e) Specifications: 100 MHz / Up to 1 Gbps An enhanced version of Cat5 with reduced crosstalk and improved performance. Widely used in home networks, SOHO environments, and for connecting routers and switches.   3. Category 6 (Cat6) Specifications: 250 MHz / Up to 1 Gbps (up to 10 Gbps at shorter distances) Offers improved shielding and reduced interference over Cat5e. Ideal for medium-sized networks requiring consistent and reliable performance.   4. Category 6a (Cat6a) Specifications: 500 MHz / Up to 10 Gbps Supports higher data rates over longer distances with better shielding. Commonly deployed in enterprise networks and data-intensive applications, such as server interconnects.   5. Category 7 (Cat7) Specifications: 600 MHz / Up to 10 Gbps Features individual shielding for each twisted pair to minimize electromagnetic interference (EMI). Suitable for high-performance environments such as data centers and backbone infrastructure.   6. Category 8 (Cat8) Specifications: 2000 MHz / Up to 25–40 Gbps (up to 30 meters) Designed for high-speed data transmission over short distances. Optimal for modern data centers, high-frequency trading platforms, and other ultra-low-latency environments.   ✅ Recommendation: Choose network cabling based on your current and future bandwidth requirements, distance limitations, and environmental factors. Higher-category cables provide faster, more stable, and interference-resistant connections critical for scalable and future-proof network design.

Why measuring loop gain matters for power supply design engineers - and how to do it correctly. When your power system oscillates at 20 kHz after a load step, it's not coincidence. Loop gain measurement shows a phase margin of only 15°. Loop gain is the key indicator of stability in power supply systems. But measuring it correctly requires proper technique: 1. Select the right frequency analyzer settings: - Narrow IF bandwidth reduces noise (but increases sweep time) - Programmable source voltage prevents circuit saturation - Servo control adjusts source amplitude automatically 2. Choose correct injection points: - Impedance looking backward should be much smaller than forward - Keep connection wires short to prevent measurement errors - Include ALL feedback paths (this is crucial) 3. The payoff? Predictable transient response: The relationship is direct: t₁ = 1/(4·fc) With proper phase margin, your circuit responds as designed. 4. Test across all operating conditions: - All output voltage settings - Full output current range - Full input voltage range - Temperature extremes Data shows the impact: In an unstable system with 15° phase margin, output oscillated exactly at the crossover frequency (20 kHz). Small details matter - even your probe reference point affects results. Are you measuring loop gain in your power designs? Or just hoping they'll be stable? Texas Instruments engineers reveal why your power supply measurements don't match simulations. The answer isn't more complex models—it's proper measurement technique at the right injection points with correct reference connections.

How do you control sound in a space without showing acoustic panels? As designers, we often want serenity without sacrificing aesthetics. So, how can we keep interiors visually clean and acoustically comfortable? Here are 5 smart ways to hide acoustic panels in your design: ✅Behind Wooden Slats Stylish vertical or angled slats with acoustic fabric/panels behind them. Ideal for walls or ceilings. ✅Integrated in Ceilings Use micro-perforated gypsum boards or acoustic tiles above false ceilings – invisible but effective. ✅Inside Furniture Add sound-absorbing foam or acoustic boards in banquette backs, headboards, or shelving nooks. ✅As Wall Art Print art on acoustic fabric or mount minimalist panels as a design feature. Looks like art, works like tech. ✅Behind Curtains or Fabric Walls Layer acoustic panels behind full-height drapery or upholstered wall panels. Soft, elegant, and sound-friendly. ℹ️Materials often used: Acoustic foam , Perforated gypsum,Wood veneer panels,Sound-absorbing fabric, Mineral wool/rock wool. The goal is harmony- between sound, space, and style. Have you used hidden acoustics in your projects? I'd love to hear your approach!

Most people think acoustics means soundproofing. It doesn't. Soundproofing stops sound from travelling between spaces. Acoustics shapes how sound behaves within a space. They are related. They are not the same. And confusing the two is where most premium rooms quietly fail their owners. Here is what good acoustics actually feels like - because almost nobody experiences it properly. You sit in the room. Music plays at a level that would normally feel loud. But it doesn't feel loud. It feels present. Every instrument sits in its own place in the air. The guitar is slightly left. The vocal is centred. The bass is below everything, felt before it is heard. You are not aware of the speakers. You are only aware of the music. That is not a system performing well. That is a room performing well. And a room only performs well when three things are addressed:   Reflection. Hard surfaces - glass, marble, flat ceilings - throw sound back at you. The right absorption materials in the right places remove the fight between direct sound and reflected sound.   Diffusion. A room that is too dead sounds unnatural. Diffusion scatters reflections so the room breathes without bouncing.   Bass control. Low frequencies pile up in corners. Without bass trapping, the same note sounds different depending on where you sit. Most rooms address none of these. Most rooms are built for how they look and expected to figure out how they sound. They never do. The good news: Acoustic treatment does not require tearing your room apart. Panels that match your décor. A rug that does more than look expensive. Curtain weight and texture chosen with purpose. The room you have can become the room you deserve. It just needs someone to listen to it first.

Every Web Developer Should Know : Here’s how I ensure every website I build is fully responsive and optimized for every screen: 1. Mobile-First Approach - Start with mobile, then scale up. - The majority of users browse on mobile devices. Always design and develop for small screens first, then use media queries to scale for larger screens. Prioritize mobile usability. 2. Flexible Layouts with Fluid Grids - Use relative units (like %, vh, vw) - instead of fixed units (like px) for widths, heights, and margins. - Fluid grids allow your layout to adapt based on the screen size, ensuring a seamless experience on any device, from phones to desktops. 3. Responsive Images - Use `srcset` and `sizes` attributes to load different image sizes based on screen resolution. ( serving better images to the user,improving the website loading time ) 4.Media Queries for Custom Breakpoints -Set breakpoints based on content, not device sizes. - Use media queries to adjust styles for different screen widths. Don’t just rely on the standard breakpoints – customize them to fit your design. 5. Viewport Meta Tag for Proper Scaling - Always include the viewport meta tag in the head of your HTML document. - This tag ensures that your website scales correctly on different devices and prevents zooming issues on mobile. 6.Optimized Fonts and Icons - Use scalable vector graphics (SVGs) for icons. - SVGs are lightweight, resolution-independent, and perfect for responsive design. - Also, use `font-display: swap` for faster text rendering and better UX.

Understanding UPF, Clock Gating, and Power Gating In the age of ever-shrinking transistors and increasingly complex SoCs, managing power consumption has become a critical aspect of semiconductor design. Efficient power management is not just about prolonging battery life but also about enhancing the overall performance and reliability of devices. Unified Power Format (UPF): UPF is a standardized methodology that allows designers to define power intent early in the design process. By using UPF, we can describe the power architecture, including power domains, power states, and the relationship between them, in a consistent and portable manner. This ensures that power management techniques like power gating and clock gating are seamlessly integrated into the design flow. Clock Gating: One of the most effective techniques to reduce dynamic power consumption is clock gating. By selectively turning off the clock signal to inactive parts of a circuit, we can significantly reduce the switching activity—one of the primary sources of power dissipation in digital circuits. Clock gating is extensively used in modern CPUs, where only the active components receive clock pulses, optimizing power usage. Power Gating: Power gating takes power management a step further by completely shutting off the power to unused modules, effectively reducing leakage power. This is crucial in battery-powered devices like smartphones and wearables, where every milliwatt saved translates to longer battery life. Power gating ensures that while essential functions remain operational, non-essential blocks are powered down, preserving energy without compromising functionality. Together, UPF, clock gating, and power gating form the backbone of low-power design strategies, enabling us to build smarter, more efficient devices that meet the demands of today's power-conscious world. #Semiconductors #LowPowerDesign #UPF #ClockGating #PowerGating #SoC #VLSI #EDA #TechInnovation
