Global Stuttering & Massive FPS Drops in PCSX2
Hi everyone,
I need help diagnosing a persistent performance issue in PCSX2 (v2.7 Nightly). I'm getting massive FPS drops (60 down to 30s) and constant micro-stuttering across ALL games, regardless of whether I use Texture Replacement packs or play on 100% Native settings.
My Specs:
CPU: Intel Core i9-9900K
GPU: NVIDIA RTX 3080 Ti
RAM: 32GB
Storage: NVMe SSD
OS: Windows 11
What I’ve already tried (None of these fixed the issue):
Windows Settings: Disabled Hardware-accelerated GPU scheduling (HAGS) and Variable Refresh Rate (VRR).
Renderers: Switched between Vulkan and DX12; enabled Asynchronous Shader Compilation.
Emulation Fixes: Adjusted EE Cycle Rate (-1, -2) and tried various Cycle Skipping settings.
Storage: Moved the emulator, games, and Cache Directory to a fast NVMe SSD.
Background Apps: Completely disabled Asus Armoury Crate services and other background processes.
Nvidia Panel: Set Power Management to "Prefer Maximum Performance."
The stuttering happens in every game I test. It feels like a CPU timing or synchronization issue between the emulator and Windows 11. Is there a known compatibility issue with the 9900K and the latest v2.7 builds, or is there a specific BIOS/OS setting I should check?
Any help would be greatly appreciated!
