GTweak is a Windows optimizer I built and ship as a licensed desktop app. Open it before a gaming session, hit Auto-Optimize, and it applies tweaks across your CPU, GPU, network and power settings in about 30 seconds — no digging through registries yourself. It also shows a live dashboard of your hardware while it's running.

What it reads off your PC

Before you touch anything, the dashboard pulls your actual hardware info so you know what you're optimizing:

• CPU — model name, current clock speed vs. max clock speed, live utilization %, and core temperature
• GPU — model name, temperature, utilization %, and VRAM used / total (via nvidia-smi)
• RAM — total installed, currently used, live usage ring
• Disk — used / total space on the C: drive
• OS & network — Windows build/caption and the name of your active network adapter

DashboardPage.xaml.cs — one of the WMI queries that feeds the CPU card:

using var cpu = new ManagementObjectSearcher(
    "SELECT Name, CurrentClockSpeed FROM Win32_Processor");
CpuInfo.Text = cpu.Get().Cast<ManagementObject>().First()["Name"].ToString();

What it optimizes

• CPU — forces max performance mode, unparks all cores, kills C-state throttling so the processor doesn't clock down mid-game
• GPU — locks to maximum power state, turns off VSync globally, enables hardware scheduling and low-latency mode
• Network — disables Windows' built-in QoS throttle, kills TCP delayed ACK, reduces latency on the network stack
• System — removes telemetry services, Game Bar, Xbox DVR, background app activity; trims startup programs
• Power — switches to Ultimate Performance plan, disables hibernation
• Safety — creates a Windows restore point before touching anything, so every change is fully reversible

How it's built

The app is split into per-category pages — CPU, GPU, RAM, Network, Power, Boot, Debloater — each showing on/off switches for individual tweaks, plus the Dashboard page above that runs everything at once. Every tweak is just a registry write or a Windows API call under the hood, wrapped in a try/catch so one failed tweak doesn't stop the rest. The live stats poll every 2 seconds using WMI for CPU/RAM and nvidia-smi for GPU, so the dashboard is never more than 2 seconds stale.

Auto-Optimize just loops over a list of 28 tweaks and applies them in order, updating a progress bar as it goes:

foreach (var tweak in tweaks)
{
    AutoProgressText.Text = tweak.name;
    await tweak.action();
}
