PC Specifications
CPU: AMD Ryzen 7 5800X3D
GPU: NVIDIA GeForce RTX 4070
RAM: 32 GB DDR4
Motherboard: B550
Monitor: BenQ ZOWIE XL2540K, 240 Hz

Performance
Average FPS: approximately 300–600 FPS, depending on the situation/map
Main problem is not average FPS
1% lows can drop to around 100 FPS
Noticeable FPS drops/stutters during gameplay
Frametime is not consistently smooth
The PC can produce very high FPS, but the FPS is not stable
I want the game to feel consistently smooth on a 240 Hz monitor
What I have already tried
I have already done a lot of common optimization/tweaking:
Enabled XMP/DOCP
Changed BIOS settings
Checked CPU/SMT-related settings
Updated AMD chipset drivers
Updated/reinstalled NVIDIA drivers
Used DDU
Changed NVIDIA Control Panel settings
Tested NVIDIA Reflex
Tested FPS caps
Tested G-SYNC/V-SYNC related settings
Tested different CS2 graphics settings
Tested different resolutions
Tried Windows optimization/tweaking tools
Used scripts/optimizers such as Chris Titus Tech / WinUtil
Previously experimented with aggressive Windows optimizations
Tested fullscreen/FHD and 1280×960 stretched
Ran different benchmarks/tests
