I can confirm that the same severe performance issues occur across multiple official DayZ servers following Update 1.30.

The issue is not map-specific. I have reproduced it on both Chernarus and Sakhal.

Before the update, DayZ ran smoothly at 4K Extreme settings, consistently maintaining my configured 120 FPS limit, matching my display's 120 Hz refresh rate. This was my display-limited operating target, not a hardware performance limitation.

Since Update 1.30, the game has suffered from severe, persistent stuttering, highly inconsistent frame times and dramatically degraded 1% lows. Reducing graphics settings from Custom through Extreme, High, Medium and even Low makes no difference.

This is not simply a reduction in average FPS. The severity of the stuttering fundamentally compromises gameplay, leaving the game in a practically unplayable state.

I have also experienced multiple crashes to desktop since the update.

These issues appeared immediately after the update. The same hardware ran DayZ smoothly beforehand, and other demanding games continue to perform normally.

System specifications:

• GPU: NVIDIA GeForce RTX 5090

• CPU: AMD Ryzen 9 9950X

• RAM: 64 GB Corsair VENGEANCE DDR5 6000 MHz CL30 (2 × 32 GB)

• Motherboard: ASUS ROG Crosshair X870E Hero

• OS: Windows 11

• Display: 4K, 120 Hz

• NVIDIA driver: Latest available version

I am preparing video evidence with frame time monitoring to document the regression.
