1,100+ exclusive optimizations crafted for a flawless, high-framerate experience. One click to apply — every change reversible from your backup history.
No sketchy scripts, no 40-tab tutorials. ONYX stages every change, tags it by risk and keeps a full manifest — so nothing is ever a mystery.
One button stages every Safe tweak plus the functionality-safe Medium ones and runs them with a live progress bar. 870+ tweaks in a single pass — nothing breaks features.
Native standby-list flush, working-set trim and file-cache cleanup with a live result. No external tools, no drivers.
Nagle, TCP profiles, DNS presets, LSO/RSC, interrupt moderation — tuned for ping, repaired when things go sideways.
Per-card packs for NVIDIA, AMD and Intel — P-states, MSI mode, HAGS, telemetry — plus Thunderbolt and eGPU presets.
Validated setups for Fortnite, CS2, R6 and more — priorities, driver profiles, configs. Process Lasso walkthroughs included.
Deep cleanup of 120+ targets, duplicate finder, large files, space analyzer, startup control, one-click maintenance.
Per-board firmware recommendations with step-by-step guidance. VIP only — the deep-locks page for your motherboard.
Grab the portable build, allow the UAC prompt, and ONYX boots with a staged loader. No installer, no background services.

Every tweak is tested and risk-tagged (Safe / Medium / Risky), Apply Recommended only uses functionality-safe items, and every change keeps its own revert. You can create a Windows restore point from inside the app before you touch anything.
Keys lock to the first PC that activates them — ONYX hashes your hardware into an anonymous fingerprint (like ONYX-CC72-B47B-0764) that our server checks. Week/month/year keys hold one device; Lifetime holds five. Deactivate inside the app to free the seat and move to a new machine.
611 premium tweaks across GPU packs, power, network, memory, input latency, services debloat and privacy — plus the BIOS adviser and the full Storage hub. Premium payloads are fetched from the licence server after activation, so they're never bundled in the download.
Activation and refreshes need internet, but ONYX keeps a verified session on your machine — if the server is briefly unreachable, your cached premium session keeps working.
Both, x64. Compatibility is tagged per OS and the app skips anything that doesn't apply to your build.
Digital goods are licence-bound, but if something doesn't work on your machine, reach out on Discord and we'll sort it out.
Portable, reversible, and free to start. The first optimization lands in about two minutes.
