New to this? See how a PC optimization works, step by step.
What We Do
Unlike automated tools or batch file tweaks, every FrameSync optimization is performed manually by an engineer via a secure, direct remote access. Our team has over 15 years of hands-on IT experience. We cover BIOS settings, Windows OS configuration, network stack tuning, input lag reduction, game-specific settings, advanced RAM timings, and component overclocking or undervolting - all tailored to the specific hardware and games each client uses. We do not sell one-size-fits-all tweaks or repackaged registry files.
FSOS - FrameSync OS
FSOS (a.k.a FSOS-X or FrameSync OS available at https://fsosx.com) is a custom-tuned Windows build developed in-house, with over 300,000 downloads to date. FSOS is included (optional) with all optimization plans completely free of charge and delivers a fully optimized operating system foundation specifically built for competitive gaming.
Benchmarking and Methodology
Our engineers use professional tools such as NVIDIA Latency Analyzer to verify the functionality of every tweak in-house before it's rolled out to customers. Other benchmarking and diagnostic tools including FrameView for frame time analysis, Intel PresentMon for frame presentation and latency tracing, LatencyMon for DPC latency measurement, HWiNFO for hardware monitoring, BenchMate for benchmark validation and result integrity, and CapFrameX for framerate capture may be used during client sessions. Every optimization includes before/after benchmarks so clients can verify measurable performance gains. All changes are tested, safe, reversible, and tailored to each individual system.
Real Benchmark Results

A dedicated engineer handles post-session assistance, while a separate community support team provides support to regular members.
Quick Evaluation - 15 Minutes, 5 EUR
Quick Evaluation is a paid 15-minute session, priced at 5 EUR, in which an engineer looks over your system and tells you honestly whether optimizing it is worth the money. If your hardware is not a good candidate, we say so and you have spent 5 EUR instead of the full price.
The evaluation covers a review of your CPU, GPU, memory and motherboard against the plan requirements, a check of what headroom your system actually has, and a straight answer on which plan (if any) suits it. It is advice only - no changes are made to your PC during the evaluation.
Custom Optimization
We offer Custom Optimization, a built-in custom plan builder on the website that lets customers hand-pick their own optimizations and build a fully tailored plan. Browse the full catalog of individual tweaks and optimizations, select exactly what you want, and Custom Optimization automatically calculates your price and session length based on your choices. Available for free directly on framesynclabs.com.
Before Your Session
A fresh Windows installation is required before an optimization session, so that we start from a clean base with no previous tweaks interfering with the work. You do not have to do it alone: after booking you receive pre-optimization instructions by email, including a quick and simple guide to the Windows installation itself. Back up anything important beforehand. A dual-boot setup is also available if you would rather not touch your existing operating system.
Secure Payments
All transactions are processed through Stripe with 256-bit SSL encryption. Accepted payment methods include Visa, Mastercard, Apple Pay, Google Pay, Klarna, PayPal, and iDEAL. All payments are fully secure with fraud protection and dispute resolution available through Stripe and PayPal.
