After the latest CS2 update, I started experiencing consistent micro-stutters and frametime instability that were not present before.
I tested this in a controlled way:
– Same PC
– Same BIOS
– Same Windows installation
– Same GPU drivers (tested multiple versions)
– Same in-game settings
When I roll back CS2 to the previous version, the game becomes 100% smooth again.
When I update to the current version, the micro-stutters immediately return.
This strongly indicates a regression introduced in the latest CS2 build.
System:
– CPU: Ryzen 7 7800X3D
– GPU: NVIDIA RTX (tested with multiple drivers: 591.74, 591.59, 591.44, 581.80)
– RAM: 96 GB
– OS: Windows 11
– BIOS: Latest available
– Monitor: High refresh rate (competitive setup)
Additional diagnostics:
Using LatencyMon, the new CS2 build causes increased DPC latency involving:
– nvlddmkm.sys (NVIDIA driver)
– dxgkrnl.sys (DirectX Graphics Kernel)
On the previous CS2 version, these spikes do not occur and frametime is stable.
This looks like a change in how the new build interacts with DirectX / NVIDIA driver scheduling, causing occasional stalls in the render pipeline.
This is very noticeable in high-FPS competitive scenarios and did not happen before the update.
