Stuttering and FPS drops in CS2 are different from just low FPS. You might average 300 FPS but still experience jarring micro-freezes that make the game feel unplayable. These frame time spikes are often worse for performance than simply having lower but stable frames.
Diagnose With Frame Time Data
Enable cl_showfps 5 in CS2 console to see frame time graphs. Use MSI Afterburner with RivaTuner to log GPU and CPU usage alongside frame times. Look for spikes that coincide with stutters — this tells you whether the bottleneck is CPU-side or GPU-side.
Shader Compilation Stutters
CS2 compiles shaders in the background when you first encounter new visual scenarios. These pre-compilation stutters typically go away after a few hours of play. If they persist, try deleting the shader cache folder under csgo/shadercache in your game files.

See Services →RAM and Virtual Memory
CS2 uses significantly more RAM than CS:GO. If you have 8GB, you're likely hitting the limit during matches. 16GB minimum is recommended. Also ensure your RAM is running at its rated speed by enabling XMP or EXPO in your BIOS.
