Most tweaking tools hand everyone the same preset. SlideTweaks scans your actual hardware, applies only the tweaks that matter on your machine — and shows you what it skipped and why.
Cut background load and give games priority across all nine tweak categories.
TCP stack, ACK frequency and adapter tuning for steadier online play.
Timer resolution, scheduling and input queues for instant response.
No mouse acceleration, no smoothing curve, raw input end to end.
Download, setup and every feature explained in one video. If you'd rather read, everything below covers the same ground.
The BEST FREE PC Tweaking Utility in 2026 — SlideTweaks Tutorial
That's my machine, not a promise. A clean modern PC gains little, a bloated one can gain a lot — which is exactly why there's a benchmark built into the app so you can measure your own.
Some tools brag about a thousand tweaks. They get there by counting every registry value separately. We'd rather tell you which ones actually do something on your machine.
One button reads your system type, cores, RAM size and speed, GPU vendor, SSD or HDD, monitor refresh rate and connection — then builds a list that fits it.
The scan runs as a panel over the app: your CPU, GPU, memory, storage and display appear one by one as they're detected, then it lands on the number of tweaks that fit.
One button if that's all you want. Nine categories, search and risk labels if it isn't.
Hardware-aware recommendations with the reasoning shown for every group — including what it left out.
Fortnite, GTA V, Valorant and an Ultra FPS set. One tap, all reversible, nothing risky included.
Finds the real FPS killers most tools ignore — RAM below its rated speed, a 165 Hz monitor stuck at 60.
Opens your NVIDIA or AMD panel and walks you through every setting with the exact value and why it matters.
Save a baseline, apply tweaks, run it again. Real percentages instead of numbers on a thumbnail.
Audio, Bluetooth, network, GTA/FiveM, Xbox, Windows Search — one click puts them back.
No hidden scripts. Each tweak tells you what it does and what it costs, and the risky ones are off by default and ask before they run.
Driver settings beat almost every registry tweak — but automating them means bundling third-party tools, which is exactly why other tweakers trip antivirus. So we open the panel for you and hand you a checklist instead.
The biggest FPS losses often aren't in the registry at all. The System Check finds them and says so plainly — even when the answer is in your BIOS.
Unedited vouches from our Discord. Gains depend entirely on your hardware — that's why there's a benchmark built into the app.
“W went from 240 stable to 350 stable and from 15 ping to 8. I vouch 10/10.”
“They good asf, I got from 70 fps to 180. Thanks 🙏”
“W tweak actually works, from 200fps to 300fps.”
“Better than risxn. +90 fps in Fortnite and +130 fps in CS2 with 0 delay.”
“Before I was at 286 fps, after applying them I managed around 350 fps. A huge jump!”
“Went from unstable 180 to stable 324+, made my delay way lower.”
“My laptop is old so I didn't get a lot of fps, but now it's more consistent and delay is practically 0. 9.5/10”
“50 fps+ in Valo, clean app design and it's free.”
“+370fps, no more delay and totally easy to install.”
“+rep best tweaker I'd ever had.”
“Really helped my pc and my fps increased around 25 ish more fps.”
“Very good, makes my fps more stable and packet loss low.”
Screenshots and full threads live in our Discord — nothing here is cherry-picked marketing copy.
Your numbers will differ: a clean, modern PC gains little, a bloated one can gain a lot.

Grab the latest build from the download channel.
Right-click → Run as administrator. Setup asks two questions and offers a restore point.
One button. Everything else is optional.
Yes — it costs no money, there's no subscription and nothing is locked behind a paywall. All I ask is that you support the project with my creator code in the Fortnite item shop. Details are in the Discord.
They get to 1000 by counting every registry value separately and padding the list with things that do nothing measurable. Ours are 179 real, documented, individually reversible changes — and Smart Optimize tells you which of them actually apply to your machine.
Press Analyze my PC and you're done. It reads your hardware, shows what fits, and applies it after you confirm. The tutorial video above walks through the whole thing.
Normal for unsigned apps. Code-signing certificates cost hundreds per year and SlideTweaks is free. Click More info → Run anyway. The full source code is public in our Discord if you want to check it first.
Yes. Flip any tweak off to revert it, or hit Reset All Tweaks. Setup also offers a Windows restore point on first launch.
It depends entirely on your system. A clean, modern PC gains little; a bloated one with XMP off can gain a lot. The reviews above range from +25 to +370 FPS for exactly that reason — measure your own with the built-in benchmark.
It reads your PC, then optimizes it. Windows 10 & 11. No catch.
