⚡ Voltvane

Free, open-source Windows PC optimizer that actually explains itself.

Most optimization tools apply registry tweaks silently with zero explanation. Voltvane shows you exactly what each tweak does, why it helps, and lets you revert everything with one click.

---

What it does

• Registry tweaks — Game DVR, fullscreen optimizations, mouse acceleration, MMCSS scheduling, timer resolution
• Power plan tuning — Custom Voltvane power plans for laptops and desktops, minimum processor state fixes
• Latency tweaks — Disable Nagle's algorithm, network throttling, GPU/SFIO priority
• Background service cleanup — SysMain, Windows Search indexing, telemetry reduction
• CPU & GPU guides — ThrottleStop, MSI Afterburner walkthroughs built into the app
• Everything is reversible — One click reverts any tweak to Windows defaults
• Creates a restore point before the first change

---

Why open source?

Because you should be able to see exactly what a PC optimizer does to your system before running it. Every tweak in TweakCatalog.cs is documented with what it changes, why it helps, and what the revert does.

Adding a tweak

All tweaks live in Services/TweakCatalog.cs. Adding one is straightforward:

list.Add(new Tweak
{
    Id = "your_tweak_id",
    Title = "Your tweak title",
    Category = "Latency & Scheduling",
    ShortDescription = "One line explaining what it does.",
    Explanation = "Full explanation shown in the app.",
    Target = FormFactor.Both,        // Both, PC, or Laptop
    Kind = TweakKind.Registry,       // Registry, PowerCfg, Command, or Guide
    Risk = RiskLevel.Safe,           // Safe, Caution, or Advanced
    IsPro = false,
    RecommendedForPC = true,
    RecommendedForLaptop = true,
    RegHive = "HKCU",
    RegPath = @"Your\Registry\Path",
    RegName = "ValueName",
    RegType = "DWORD",
    RegValueApply = "1",
    RegValueRevert = "0"
});
