System Priority Telemetry Flow
MMCSS Status: OnlineUNLOCK YOUR MOUSE'S POTENTIAL
While 8KHz gaming mice are gaining widespread adoption, most game engines are still not optimized for ultra-precise mouse inputs, even on the best processors. ReflexCore's native Kernel DPC Lane Shunting (KDLS) forces game engines to accept raw, multithreaded input, turning high polling rates from a latency liability to a competitive advantage on adequate hardware. ⚡ STABILITY DELTA: KDLS eliminated or nearly eliminated frame drops caused by input data volume at 8KHz mouse polling in all Unreal Engine games tested, along with non-Unreal Engine games that were previously not running smooth with 8k. 👑 NOTE: Extreme 8K device polling is universally unlocked across all compiled profiles below natively on High-End systems running Pro Mode.
Upgrade to Pro Suite
Free builds apply baseline file scheduling adjustments. Pro activations drop low-level hardware constraints to handle raw 8K packet routing queues flawlessly.

⭐ Super KDLS & 8K Shield
Expands Windows USB input queue boundaries to 1024 data matrices and spins up a dedicated background Win32 worker thread. High-polling 4K and 8K gaming mice communicate with 0% dropped packages or context-switching stalls.
⭐ GPU Exclusive MSI-X Shunt
Bypasses legacy line-signaled pin interrupts. Shifts your primary graphics driver registers directly into Message Signaled Interrupts mode, eliminating multi-core IRQ bottleneck stutters safely.
⭐ Max Polling Overdrive
A nuclear kernel execution block that zeroes out system DMA pacing and forces ThreadPriorityOverdrive values to their absolute limits, maximizing raw peripheral-to-screen latency transfer.
⭐ Tournament Kiosk Mode
A dedicated watchdog loop that terminates explorer.exe completely the moment your gaming process hits foreground focus, reclaiming full window compositor overhead blocks. Restores safely upon game exit.
⭐ Win32 Priority Separation
Modifies CPU core runtime scheduling separation loops inside the NT sub-kernel. Dedicates massive variable process quantums directly to the foreground game window, isolating it from background thread load noise.
⭐ TCP/IP Network Overrides
Disables Nagle's Algorithm and the standard OS Network Throttling Index, ensuring game packets are dispatched to the router instantly without buffering delays.
⭐ Memory Tweak Loop
Evaluates and systematically closes bloated background applications (Chrome, Discord WebHelper) and flushes standby list caches when physical memory caps run narrow.
⭐ Hardware Accelerated GPU
Forces HAGS activation and locks DirectX shader pre-caching boundaries, offloading thread scheduling from the CPU directly into the GPU's memory bus.

Help & Technical FAQ
Is ReflexCore safe to run with anti-cheat software (Vanguard, FaceIt)?
Yes, 100%. ReflexCore is completely external. It modifies native Windows parameters, Registry settings, and driver alignment profiles using standard system hooks. It never opens handles, touches game binaries, or reads game memory spaces.
Why does my mouse cursor freeze for two seconds when initializing optimization?
To isolate peripheral interrupts from CPU Core 0, the Super DPC engine triggers an instant hardware cycle. It momentarily resets the motherboard's active USB host controllers via PowerShell to re-route memory channels safely without requiring a full PC reboot.
Do I need Administrator privileges?
Yes. Affinity masks, timer resolution, power plans, BCD edits, and Task Scheduler startup all require an elevated process. The app will prompt for UAC if you launch without admin.
What is the difference between Free and Pro?
Free includes baseline toggles like dynamic tick control, thread priority, NTFS stamp disable, quick actions, telemetry, and startup. Pro unlocks KDLS, 8K Shield, MSI-X shunt, Tournament Mode, memory purge loops, HAGS, GameDVR/FSO/telemetry kills, and competitive presets.
Where do I buy Pro and activate it?
Use Get Pro License on this site or the in-app button PURCHASE PRO KEY (REFLEXCORE.XYZ). Checkout is on Polar. Paste your key in the LICENSE tab and activate. Restart if themes do not refresh immediately.
What is discount code REFLEX99?
REFLEX99 is the checkout cipher for the current $9.99 lifetime Pro map (marked down from $14.99). Apply it on the Polar payment page when prompted.
Will ReflexCore ban me?
ReflexCore does not inject into games. Still follow your game publisher and tournament rules. If a league forbids system tweaks or overlays, disable those features for that event.
What DPI should I use for 8K polling?
Set mouse DPI to 1600+ in Synapse, G HUB, iCUE, Wootility, or your vendor software. Low DPI at 8000 Hz can starve UE4/UE5 packet queues and cause hitching.
Does Full 8K Isolation work on every CPU?
It works best on CPUs with enough cores to reserve 0/1 for USB IRQs while the game runs elsewhere. Dual-core and very low-end systems should keep Max Polling / Isolation off.
What does Tournament Kiosk Mode do?
It suspends explorer.exe during active optimization so the desktop shell cannot steal focus or burn cycles. When you stop optimization, Explorer is restored.
Can I undo changes?
Most toggles are reversible by turning them off and stopping optimization. Startup tasks can be removed with RUN ON STARTUP: OFF. For BCD/power plan changes, reverse the same toggles or restore a Windows restore point.
Why does Windows Defender flag the installer?
Unsigned competitive tools that touch timers, affinities, and registry often get heuristic detections. Download only from [reflexcore.xyz](https://reflexcore.xyz) or [official GitHub releases](https://github.com/MintyLiteralGod/ReflexCore-FPS-Booster/releases), then allow the file if you trust the source.
Does it support Windows 10 and Windows 11?
Yes. ReflexCore targets Windows 10/11 x64. Some features (HAGS, certain power schemes) depend on your GPU driver and Windows edition.
Single-file exe is huge — is that normal?
Yes. Self-contained .NET 8 + Windows Desktop + ReadyToRun packs the runtime into one executable. Size does not mean the app is mining or bundling unrelated software.
How do I add a custom game?
On the Dashboard, use Active Target Game Executables and ADD EXECUTABLE. Enter the process name without path issues (for example game.exe). Multiple names can be comma-separated depending on your config field.
What is KDLS?
Kernel DPC Lane Shunting expands USB/input queue capacity and isolates high-rate mouse traffic so 4K/8K polling does not collapse frame times on engines that were never designed for that interrupt volume.
What is RIDEV_NOLEGACY / 8K Shield?
It registers raw mouse input with RIDEV_NOLEGACY so Windows legacy cursor path is swallowed while a game is focused. Expect the desktop cursor to disappear under game focus until optimization stops.
My mouse software (Synapse/G HUB) conflicts — what now?
Close or disable competing input filters (including RawAccel-style hooks) before engaging Max Polling. ReflexCore's watchdog warns when conflicting filters are detected.
Does obfuscation mean the app is malware?
No. Release builds run Obfuscar to rename private symbols before publish. That protects IP; it does not hide network miners. Prefer official builds and check the publisher/signature when available.
Can I run ReflexCore minimized?
Yes. While optimization is active, closing the window hides to tray instead of exiting. Use the tray menu to reopen or shut down cleanly.
Does it work with laptops?
Yes, but results vary. Disable battery saver, plug in AC power, and avoid Ultimate Performance on unstable OEM power plans if thermals spike.
Will it break my audio?
Pro audio buffer shunting lowers latency buffers. If you hear crackles, disable that path / stop optimization and raise buffer size in your audio interface panel.
How often should I run optimization?
Leave it engaged for the session you are playing. Stop it when you are done if you use Tournament Mode or 8K Shield so desktop behavior returns to normal.
Is there a refund policy for Pro?
License fulfillment is handled by Polar checkout. Use the Polar customer portal / support flow tied to your purchase email for billing issues.
The site says Desktop Required on my phone — why?
The marketing UI mirrors the desktop app shell. You can tap View Site Anyway, but downloads and configuration are intended for a Windows PC.
Where is the changelog?
Open the Changelogs tab in the left nav, or click Changes in the top update banner for v1.5.0 notes.
Can I use ReflexCore with Process Lasso / ParkControl?
You can, but overlapping affinity tools may fight each other. Prefer one authority for core parking/affinity. ReflexCore's isolator expects to own the game mask while engaged.
Does Pro include future updates?
The current offer is a lifetime node license for the Pro feature matrix. Feature additions ship through app updates; check the site/changelog for version notes.
Why is timer resolution forced to 0.5ms?
Windows default tick granularity is too coarse for high-rate input pacing. ReflexCore clamps multimedia timer resolution so sleep/yield paths stay consistent during play.
Steam / Epic overlays still cause hitching — help?
Disable Game Bar/DVR in Pro toggles, turn off heavy overlays, and avoid recording software while testing input. Overlays can reintroduce the same stalls ReflexCore tries to remove.
