We tested 15 popular FPS boost tips that gamers swear by — and most of them don’t actually work. Find out which “tweaks” are wasting your time and what to do instead.
You’ve probably watched a dozen YouTube videos promising “+50 FPS with this one tweak” — and then felt nothing after spending an hour applying every single tip in the list. You’re not alone, and you’re not doing it wrong. The truth is that a huge chunk of the FPS boost advice floating around the internet in 2026 is either outdated, placebo-level effective, or just plain wrong.
In this article, we put 15 of the most popular FPS “boosts” to the test — the ones you’ll find in nearly every optimization guide, Reddit thread, and YouTube video. We’ll tell you exactly what each one does (or doesn’t do), why it got popular in the first place, and what actually works instead. By the end, you’ll stop wasting time on fake fixes and start spending your energy on tweaks that genuinely move the needle.
Why So Many FPS Myths Exist
Before jumping in, it’s worth understanding how these myths spread. A lot of optimization guides were written years ago for Windows 7 or early Windows 10 builds. Back then, some of these tweaks did make a difference. But Windows 11, modern drivers, and modern game engines have made many of them irrelevant — or even counterproductive.
Add in the placebo effect (you want it to work, so it feels like it does), inconsistent benchmarking methods, and influencers copying each other’s lists without testing, and you get the ecosystem we have today: a swamp of fake fixes that keeps getting recycled.
Let’s drain it.
Myth #1: Disabling Core Parking Boosts FPS
Verdict: Mostly useless on modern hardware.
Core parking is a Windows power feature that puts idle CPU cores to sleep. Years ago, disabling it manually via registry edits was a popular tweak. The idea sounded logical — why let cores sleep when you’re gaming?
The problem is that Windows has handled this automatically since Windows 10. If you’re running a High Performance or Ultimate Performance power plan, core parking is already disabled by the OS during load. Editing the registry manually achieves nothing extra and can sometimes cause instability on laptops.
What to do instead: Set your power plan correctly. Check out our guide on Best Power Plan Settings for Gaming — that’s where real gains come from.
Myth #2: Clearing Your RAM with a “RAM Cleaner” App Improves FPS
Verdict: It actively hurts performance.
RAM cleaner tools like RAMMap flushers or “memory optimizer” apps promise to free up RAM so games have more to work with. What they actually do is flush your standby memory — RAM that Windows has pre-loaded with data it thinks you’ll need soon.
When you force-clear it, your system has to reload everything from scratch the next time it’s needed. That means more stutters, longer load times, and in some cases, actual FPS drops during gameplay. Windows’ memory management is smarter than these tools give it credit for.
What to do instead: Close actual background apps that are consuming RAM actively. Here’s how to stop background apps from killing your FPS in Windows 11.
Myth #3: Setting CPU Affinity for a Game Gives More FPS
Verdict: Almost never helps, often hurts.
Right-clicking a process in Task Manager and manually assigning it to specific CPU cores sounds like a pro move. In reality, you’re fighting against the Windows scheduler, which is already very good at distributing game threads across cores dynamically.
Pinning a game to fewer cores can actually starve it of resources when it needs to burst. Modern games like CS2, Valorant, and GTA V are built to use multiple cores and threads — locking them to two or four cores manually defeats the purpose.
Myth #4: Boosting Virtual Memory to 4x Your RAM Fixes Stuttering
Verdict: Doesn’t help, and may make things worse.
The old advice of setting your pagefile (virtual memory) to 1.5x or 4x your physical RAM was relevant when PCs had 512MB of RAM. Today, if you have 8GB or more, Windows manages the pagefile intelligently. Massively inflating it doesn’t give you “extra performance RAM” — the pagefile is on your drive, which is orders of magnitude slower than actual RAM.
If you’re genuinely running out of RAM (watching Task Manager confirms this), the real fix is adding more physical RAM, not inflating virtual memory.
Myth #5: Gaming Mode in Windows 11 Lowers FPS
Verdict: Mostly a myth — Game Mode is fine.
This one goes the opposite direction. Plenty of guides tell you to disable Windows Game Mode because it “causes stutters.” In 2026, this advice is outdated. Microsoft patched Game Mode years ago. On modern hardware, it correctly prioritizes your game process and helps prevent background Windows Update tasks from interrupting your session.
Unless you’re on a very old build of Windows 10, leave Game Mode on.
Myth #6: Deleting Shader Cache Gives You More FPS
Verdict: It actually makes things worse temporarily.
Shader caches exist for a reason — your GPU stores pre-compiled shaders so it doesn’t have to recompile them every session. Deleting the cache means the GPU has to rebuild it from scratch, which causes major stuttering during the first play session after the deletion.
Some guides suggest doing this to “fix corrupted shaders.” That’s only valid if you’re actually experiencing shader-related crashes. Otherwise, leave it alone.
Myth #7: Disabling Fullscreen Optimizations Always Boosts FPS
Verdict: Situational — not a universal fix.
Disabling FSO (Fullscreen Optimizations) through the game’s .exe properties is one of the most widely shared tips on Reddit. In some older games or specific configurations, it does help with input lag. But in 2026, most modern games use their own fullscreen implementations that already bypass FSO entirely.
Blanket-applying this to every game in your library won’t suddenly unlock 20 extra FPS. If you’re experiencing choppy frames despite good hardware, read our full breakdown on high FPS but still choppy gameplay and input lag — the real culprits are usually frame pacing and V-Sync settings.
Myth #8: Third-Party “FPS Booster” and Game Optimizer Apps Add Significant FPS
Verdict: Most add nothing. Some add malware.
Apps with names like “Razer Cortex,” “Game Fire,” “Smart Game Booster,” and dozens of imitators promise double-digit FPS gains. What they typically do is close a few background processes (which you can do yourself for free in Task Manager) and sometimes lower Windows visual effects.
The actual performance gain is near zero on a properly configured system. Worse, many free “optimizer” apps in this category are bundled with adware or behave like PUPs (potentially unwanted programs).

Myth #9: Turning Off Hardware-Accelerated GPU Scheduling (HAGS) Always Improves Performance
Verdict: Depends on your GPU generation.
HAGS was buggy on launch in 2020, which is why guides told people to turn it off. In 2026, if you have an RTX 30/40/50 series or an RX 6000/7000 series card, HAGS is well-optimized and can actually reduce CPU overhead. Disabling it on modern cards often has zero benefit or causes a slight regression.
Check your specific GPU before making this change. Blanket “disable HAGS” advice is years out of date.
Myth #10: Updating to the Latest GPU Driver Always Improves FPS
Verdict: Sometimes true, sometimes the opposite.
New driver releases are often game-specific — they optimize for a newly launched title at the expense of older ones. Blindly updating to the latest driver can actually break performance in games you already play well.
The smart move is to check driver patch notes, monitor community reports on forums like Reddit’s r/nvidia or r/Amd after a new release, and only update if there’s a known fix for a game you play. NVIDIA’s driver settings matter too — not just the version number.
Myth #11: Lowering Resolution Always Fixes Stuttering
Verdict: It helps FPS but doesn’t fix stutters.
Dropping from 1080p to 720p will absolutely raise your average FPS. But if you’re experiencing micro-stutters, frame drops every few seconds, or rubber banding, resolution is rarely the cause. Stuttering is almost always a CPU bottleneck, background process, or VRAM overflow issue — not a GPU raw power problem.
Lowering resolution treats the symptom (low FPS) but not the disease (stuttering). Our guide on FPS drops every few seconds and how to fix them covers this in detail.
Myth #12: Overclocking RAM Always Gives Big Gaming FPS Gains
Verdict: Real but often overstated.
Enabling XMP/EXPO to run your RAM at its rated speed (say, 3200MHz instead of 2133MHz) is a legitimate and free performance gain. But guides that promise “+30 FPS from RAM OC” are cherry-picking extreme scenarios, usually on AMD Ryzen systems that are heavily RAM-latency dependent.
On Intel systems or in GPU-bound games, RAM speed differences often produce single-digit FPS gains. It’s worth enabling XMP if you haven’t — but don’t expect miracles.
Myth #13: Disabling Windows Search and Superfetch Always Helps Gaming
Verdict: Only useful on HDDs, irrelevant on SSDs.
This was solid advice back when spinning hard drives were common. Superfetch (now called SysMain) would pre-load apps into RAM, causing disk thrashing that impacted game performance. On an HDD, disabling it helped.
On an SSD — which most modern gaming PCs use — SysMain does almost nothing noticeable. Disabling it gains you essentially zero performance and removes a feature that can speed up app launch times.
Myth #14: Setting Game Priority to “High” in Task Manager Gives More FPS
Verdict: Marginal to no effect on modern systems.
Setting a game’s process to “High” or “Realtime” priority sounds logical. In practice, Windows already de-prioritizes background processes during gaming automatically. Setting games to Realtime priority can actually cause system instability since it pushes the game above critical OS processes.
“High” priority is safe but provides little measurable FPS difference on a system that isn’t bottlenecked by other heavy processes.
Myth #15: More Thermal Paste Always Equals Lower Temps and Better FPS
Verdict: Only if your current paste is old or poorly applied.
Reapplying thermal paste is a real fix — but only when your CPU is actually thermal throttling due to degraded or improperly applied paste. If your chip isn’t throttling, replacing fresh paste with new paste won’t change temperatures meaningfully.
The test is simple: open HWiNFO64 or MSI Afterburner while gaming and check if your CPU is hitting its thermal limit (usually 95°C+ on modern Intel chips, 90°C+ on Ryzen). If it is, new paste or better cooling genuinely helps. If not, it’s a waste of time.
What Actually Works: Quick Reference Table
| Tweak | Does It Work? | Notes |
|---|---|---|
| Correct Power Plan (High Perf / Ultimate) | ✅ Yes | Real, consistent gain |
| Closing actual background apps | ✅ Yes | Frees CPU + RAM genuinely |
| In-game graphics settings optimization | ✅ Yes | Biggest single FPS lever |
| Enabling XMP/EXPO in BIOS | ✅ Yes | Free, safe, worthwhile |
| Lowering resolution | ✅ Yes (FPS) | Doesn’t fix stutters |
| RAM cleaner apps | ❌ No | Hurts performance |
| CPU affinity pinning | ❌ No | Fights the scheduler |
| Fake FPS booster apps | ❌ No | Often harmful |
| Core parking registry edits | ❌ No | Already handled by OS |
| Deleting shader cache | ❌ No | Causes more stutters |
The Takeaway: Stop Chasing Fake Gains
The most effective FPS optimizations in 2026 are almost always the least exciting ones: a proper power plan, clean driver install, correct in-game settings, closing unused background processes, and making sure your hardware isn’t thermal throttling. None of these involve sketchy registry edits or mystery software.
The gaming community’s obsession with secret tweaks is understandable — everyone wants more performance for free. But spending three hours applying 20 fake fixes is worse than spending 20 minutes doing the three things that actually work.

External Resources Worth Reading
For deeper technical context on how Windows manages game performance, these two sources are worth bookmarking:
- Microsoft’s official documentation on Game Mode and GPU scheduling — straight from the source on what these features actually do.
- Digital Foundry’s hardware analysis content on Eurogamer — one of the few outlets that benchmarks performance claims with real methodology.
Summary
Most of the FPS boost advice recycled across YouTube and Reddit in 2026 is outdated, exaggerated, or simply wrong. Core parking edits, RAM cleaners, priority tweaks, and fake optimizer apps aren’t going to unlock hidden performance. Modern Windows and modern drivers handle most of this automatically.
Your real levers are: a correct power plan, closing genuine background hogs, XMP enabled in BIOS, optimized in-game settings, and keeping your hardware cool. Focus there, ignore the noise, and you’ll see results that actually hold up across benchmark runs — not just feel like they do because you want them to.
