When I first upgraded to Windows 11 in late 2021, I didn't find performance to be a big issue. In fact, the transition itself was pretty smooth, which I expected since I had a Ryzen 9 5900X paired with the RTX 3090 and 64GB of RAM. Boot times were fast, apps launched without hiccups, and nothing really felt out of place besides the visual overhaul. However, that perception slowly changed over time, especially once the novelty wore off after several updates.

Sure, my PC was still objectively fast, but Windows didn't really feel as responsive as it should have. Even basic things like opening menus and launching apps weren't as snappy as they used to be. I even checked my CPU and RAM usage, but everything looked perfectly normal. That's what made the experience so confusing. The OS felt sluggish, even though my hardware was more than capable of handling the latest AAA titles. It took a couple of weeks of messing with Windows 11 settings to realize the problem wasn't really raw performance, but a few features quietly affecting its responsiveness.

Transparency effects

That glossy UI looks great, but comes at a cost

One of the first things I genuinely liked about Windows 11 at launch was how polished everything looked. The translucent taskbar, frosted menus, and subtle blur effects gave the OS a modern, almost premium feel. But once I got used to that look, the aesthetics mattered less, and eventually, I cared more about how the system actually felt to use. That's when I began noticing subtle responsiveness issues that I hadn’t paid much attention to before. When menus don't snap open as you expect them to, you start to question whether something is wrong with your system.

The problem is, when transparency effects are enabled, Windows has to render layers, apply blur, and dynamically blend interface elements with whatever sits behind them. That workload may sound trivial, especially when you have a high-end GPU, but it's happening constantly across the entire desktop. Every time you open the Start menu, switch between windows, or interact with the UI, Windows is doing extra work behind the scenes just for aesthetics. But once I disabled it by heading to Settings -> Personalization -> Colors -> Transparency effects, every desktop interaction felt lighter and more responsive.

Animation effects

Fluid animations just don't feel as fast as instant transitions

I'm sure we can all agree that Windows 11 leans heavily into animation. When menus fade smoothly, and transitions stretch just long enough to make navigation visually pleasing, the interface certainly feels modern and refined. But that fine level of detail comes at the cost of perceived speed. I'll admit I did enjoy those animations when I first upgraded to Windows 11, but once the honeymoon phase ended, I wanted everyday interactions to feel more instantaneous.

That's why I decided to disable animation effects altogether by heading to Accessibility -> Visual effects -> Animation effects. No, my PC didn't get slower over the years, but that subtle delay every time I opened a new menu started to bother me a bit. With these effects disabled, everything felt more responsive. Sure, it doesn't look as modern anymore, but when menus open without a split-second transition period, you appreciate just how immediate and snappy Windows can feel without them.

Startup apps

The performance drain I didn't take seriously for far too long

One of the main reasons Windows feels snappy after a clean install is that there's very little running in the background. The OS boots into a relatively uncluttered state, free from game launchers, third-party services, and background utilities that tend to accumulate over time. That was exactly my experience when I installed Windows 11 on my PC for the first time. But over the course of four years, as I installed a bunch of apps for gaming, streaming, performance monitoring, photo editing, and more, that responsive feeling slowly started to slip away.

When I checked the list of startup apps in Task Manager, I was honestly surprised by how crowded it had become over the span of a few years. From Adobe's CCXProcess to Overwolf Launcher and the GoXLR app, many apps have quietly added themselves to the startup process. Individually, none of them were particularly demanding by any means, but when they pile up, they collectively eat into system resources and make your PC feel slower after the initial boot. Now, I make sure only essential apps are allowed to launch at startup. The difference was immediately obvious when I cleaned things up for the first time.

Background activity

Some apps quietly ate into system resources while gaming

Minimizing startup apps does help reduce the number of background apps, but it doesn't eliminate the problem entirely. Many apps that I routinely open quietly minimize to the system tray and continue running long after I’ve stopped actively using them. Over time, I realized just how many utilities, launchers, and helper processes were lingering in the background, even during gaming sessions. For instance, I don't want the Epic Games launcher running in the background when I'm playing Valorant.

Of course, individually, these apps barely register in terms of resource usage, and that's exactly why I ignored them for a few years. But the problem is, they do add up over time, and when you're chasing every last FPS, minimizing background activity can make a meaningful difference. That's why I took my time to clean up background apps by heading to Settings -> Installed apps -> More (...) -> Advanced options -> Background app permissions and by using Task Manager. You won't find advanced options for traditional desktop apps, but many of them still offer settings that control whether they continue running after you close them.

Some features just hurt more than they help

I'm sure some of you already knew these tweaks to make Windows 11 feel snappier, but it took me far longer than I'd like to admit to fully appreciate their impact. Since my hardware was never really a problem, I didn't think twice about having a bunch of apps running in the background or keeping animations enabled. Sometimes, perceived responsiveness is simply about reducing unnecessary overhead that quietly builds up over time, regardless of how powerful your PC is.
