Will turning off Core Isolation make my PC vulnerable to viruses?

Standard antivirus protection (Windows Defender, real-time protection, firewall) remains 100% active. VBS is designed for enterprise corporate environments to protect against specialized local memory injection attacks.

Root Cause Bottleneck SecureKernel.exe / hvix64.exe / Virtualization-Based Security

Hypervisor Intercept Overhead on Ring 0 Kernel Operations

When VBS/HVCI is active, every kernel driver call (including GPU and mouse interrupts) must pass through a virtualized hypervisor layer, inducing measurable input delay and micro-stutters.

Core Isolation runs Windows inside a lightweight Hyper-V virtual machine for enterprise security. For competitive gaming, this virtualization layer adds 2-5ms of button-to-pixel latency and causes frequent DPC spikes in nvlddmkm.sys. We safely disable VBS, HVCI, and Credential Guard while preserving essential security definitions.
