System optimization — 100% free

It reads your PC first.
Then it optimizes.

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.

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.

What makes it different

Relevance, not volume

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.

Smart Optimize showing recommended and skipped tweaks

Smart Optimize

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.

Nothing is applied until you confirm
Every group explained — you see the reason, not just the name
All reversible — individually or all at once

Recommended for you

  • 32 GB RAM — plenty of headroom, so memory compression goes off
  • NVIDIA detected — MSI mode and driver telemetry off
  • On Ethernet — full latency tuning applies
  • 8 cores — timers spread across them instead of loading core 0
Two seconds

Watch it read your machine

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.

179 tweaks in nine categories, each labelled Safe / Advanced / Risky
4 game presets — Fortnite, GTA V, Valorant, Ultra FPS
Desktop and laptop aware from the first launch
SlideTweaks hardware scan
What's inside

Simple enough for anyone.
Deep enough for tweakers.

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.

Game Presets

Fortnite, GTA V, Valorant and an Ultra FPS set. One tap, all reversible, nothing risky included.

System Check

Finds the real FPS killers most tools ignore — RAM below its rated speed, a 165 Hz monitor stuck at 60.

SlideTweaks tweak cards with risk labels
Full control

179 tweaks, every one explained

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.

Safe — harmless, recommended for anyone
Advanced — real gains if you know what you want
Risky — powerful but weakens security; always your choice
The honest part

We won't fake the GPU panel

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.

Even when the fix isn't in our app

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.

RAM below rated speed — XMP off can cost 10–20% in CPU-limited games
Monitor not at max Hz — extremely common, instantly fixable
Old drivers, full system drive, bloated startup

Questions

Straight answers

Is it really free?

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.

Other tools say they have 1000 tweaks. You have 179?

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.

I'm not technical. Can I use it?

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.

Windows says "unknown publisher" — is that bad?

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.

Can I undo the changes?

Yes. Flip any tweak off to revert it, or hit Reset All Tweaks. Setup also offers a Windows restore point on first launch.

How much FPS will I gain?

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.
