Welcome to the Quantum Engineering Lab
The Quantum Engineering Lab by Pb Linux Gaming is a specialized utility designed to help Linux gamers and tinkerers simulate, test, and refine hardware-to-kernel interactions specific to gaming environments. Built for technically curious users, this tool offers modular testing components and predictive modeling to emulate performance changes before applying real-world tweaks. Whether you’re optimizing CPU affinity, experimenting with real-time kernels, or analyzing Wine/Proton interaction layers, this is your virtual playground.
Rooted in our Linux-first philosophy, Quantum Engineering Lab works best when used by intermediate-to-advanced Linux enthusiasts looking to reconcile theory with application. It’s a precision tool that promotes pre-deployment insight—helping you determine “what happens if…” before making a kernel-level change.
What You Can Do With This Tool
- Simulate Kernel Flags and Scheduling Modes: Understand how different kernel configurations influence in-game frame latency and system responsiveness.
- Analyze Bottlenecks in Real-Time: Use hypothetical setups to trace pathing bottlenecks between CPU, GPU, and shared memory.
- Estimate Proton/Wine Compatibility Shifts: See how various patches or driver versions might alter compatibility scores.
- Evaluate Module Loading Logic: Preview the boot-time handling of kernel modules, such as those supporting gaming peripherals or obscure chipsets.
- Visualize Load-Balanced Multi-Core Affinity: Test how different affinity maps affect game threading behavior under various system loads.
- Engineer Power Usage Patterns: Model how undervolting and governor behavior shift power use and thermal output during gameplay.
Localization applies in identifying microcode relevance: regional CPU microcode updates (e.g., AMD AGESA versions in North America) or driver regulation shifts in California may affect performance. The tool adapts to this via modular metadata when available.
How It Works (Step-by-Step)
- Define Your System Profile: Input your distro, kernel version, CPU/GPU models, and RAM. Optional: upload
inxioutput for greater detail. - Select Modules to Simulate: Choose what you wish to test—e.g., kernel scheduler behavior, power scaling, or module order logistics.
- Input Parameters: Select flags, sysctl values, or wine/proton patches. Optional inputs refine accuracy—e.g., RAM timings or thermal/power limits.
- Initiate Simulation Run: The virtual environment mocks the specified scenario using a heuristic model based on real-world logs, open benchmarks, and distribution defaults.
- Review Results: Metrics include simulated latency, responsiveness, compatibility estimate, power draw, and risk level.
- Export and Compare: You can export results as CSV or side-by-side views, aiding iterative experimentation.
Proprietary logic in this Lab translates kernel-level adjustments into impact vectors by referencing runtime averages from aggregated user-submitted data, carefully anonymized and normalized. No personal identifiers or installed packages are retained.

Use Cases and Examples
User Scenario 1: Proton Compatibility Concerns
Leo is testing a custom Proton-GE version after noticing shader cache rebuilds mid-game. He inputs his Arch-based setup, selects Proton patch mapping, and simulates various DLL override settings. The Lab suggests the recent DXVK commit in his build increases VRAM paging. Conclusion: he reverts and regains stable frame pacing.
User Scenario 2: Real-Time Kernel Evaluation (Localized)
Zoey, based in Southern California, is tuning a real-time kernel with custom CPU governors for low-latency rhythm games. By using the Engineering Lab and selecting a pre-mapped AGESA code for her Ryzen 7, she learns a specific TSC synchronization mismatch may elevate jitter. Simulation helps her identify a safe governor-to-TSC combo before deploy.
User Scenario 3: Multi-threaded Layout Analysis
Rajiv wants to optimize Deus Ex: Mankind Divided on Fedora 38 with an i7-12700H. Using the affinity mapping tool, he recasts 8 performance cores to handle asynchronous loading only. The simulation flags a 12% overhead reduction opportunity, which he manually tests later. Accurate? Yes. Time-saving? Definitely.
Tips for Best Results
- Make sure your system details (kernel, CPU, GPU) are accurate—use
inxi -Ffor fast copy/paste. - If unsure about flags or governors, start with pre-sets tied to your distro for safer modeling.
- Smaller, focused simulations yield cleaner results than all-in-one scenarios.
- Avoid rounding up CPU or RAM stats—precise values fine-tune predictions.
- Upload logs when exploring performance dips during gameplay; metadata reveals more than guesses.
- Interpret “risk rating” in context—it is a heuristic, not a direct warning.
- Repeat simulations with incremental changes—you’ll see clearer causation patterns.
Limitations and Assumptions
The Quantum Engineering Lab is currently in beta with evolving accuracy driven by growing dataset contributions. It does not execute real-time system commands or touch your live kernel—it is strictly an inference engine based on documented logic trees and known compatibility patterns.
Outputs represent best-effort simulations based on open-source documentation, user-submitted logs, and upstream kernel notes. For mission-critical deployments, always consult with a qualified systems engineer.
Not all hardware combinations are yet mapped; rare setups (e.g., niche ARM distributions) may produce generic results. External databases queried include open-wine compatibility logs and public GPU cross-indexes.
Privacy, Data Handling, and Cookies
Your data matters. The Lab processes all inputs client-side for most simulations. When optional logs are uploaded, they are stored in RAM cache during session only and deleted upon browser exit or inactivity timeout.
Aggregated, anonymized configurations may be stored to improve simulation accuracy—but never include personal identifiers, IP addresses, or direct system commands.

Accessibility and Device Support
The Quantum Engineering Lab supports full keyboard navigation, screen reader labels, and avoids information represented by color alone. Our developers comply with WCAG 2.1 AA standards in semantic markup.
The tool is fully responsive and performs smoothly on modern desktop and tablet browsers. Due to interface density, phones are supported via scrolling layout and collapsibles. If the Lab is offline or inaccessible, users can fall back on a downloadable performance simulation spreadsheet available from our Smart Process Hub.
Troubleshooting and FAQs
What if I enter incorrect system specs?
The tool warns you about inconsistencies and lets you revise inputs without restarting.
Can this Lab actually alter my system?
No. It’s a visualization and testing environment only—your actual kernel or config files remain untouched.
Why do some fields have “Generic Simulation Only”?
That means your component isn’t mapped in our database yet, so averages are used instead of specialized profiles.
It seems slow to process—why?
High complexity simulations (e.g., 5+ modules, power tuning + scheduler + affinity) may take up to 4 minutes. Try modular runs.
How accurate are the results?
Expect 70–90% alignment with real-world patterns on well-supported setups. Output is suggestive, not prescription.
What browsers are supported?
Chrome, Firefox, Edge, Brave on current versions. Safari support is limited due to JS model threading issues.
What are the input upload limits?
2MB max, formats: .txt, .log, .json. No executables accepted.
Is my data private?
Yes. All uploaded content is sandboxed, session-tied, and never stored long-term. See our full Privacy Policy.
What should I do after running a test?
Consider exporting your profile, comparing setups, and sharing insights with our open-source visionary community.
