Synapse 3 & 4 BOTH cause system freezes - 166K context switches/sec on AMD Ryzen

**Device:** Razer Ornata V3 X (Wired, Turkish Q layout)
**System:** Windows 11, AMD Ryzen 16-core

## Issue
Random 100-200ms system-wide freezes every 5-10 seconds when ANY Razer software is running. Affects games (Valorant, CS:GO), browsing, everything. Even only restarted and without start any apps except Razer auto-start.

## What I Tested
- Synapse 3 - freezes occur
- Synapse 4 - freezes occur
- Complete uninstall of all Razer software - NO FREEZES

## Diagnostic Data (Windows Performance Counters)
- Context switches: **166,588/sec** (normal is 20,000-50,000)
- Interrupts: 60,000-100,000/sec
- After uninstalling all Razer software: Context switches drop to normal, freezes completely stop

## Problematic Services Identified
- Razer Chroma SDK Server
- Razer Chroma Stream Server
- Razer Game Manager Service
- Razer Central Service
- Razer Synapse Service

## Important Observation
When I tried to disable these services using Windows `sc config`, they auto-restart after ~2 minutes. While trying to stop them, the freezing became EXTREMELY severe - almost unusable. This suggests aggressive watchdog behavior.

## My Problem
I need Razer software because my Ornata V3 X has no onboard memory - settings require Synapse to be running. But I cannot use my PC with Synapse installed.

## Request
Has anyone found a workaround? Is there a lightweight driver-only mode without the background services? Any help appreciated.
