Players in CS2 often experience FPS drops, even when the game previously ran smoothly. This is especially noticeable during intense rounds — explosions, flashbangs, or opening a CS2 case can cause a sudden performance hit. The main culprit is high var, a stat that measures frame inconsistency. Even with high FPS, gameplay may lag if var exceeds 1.5.
A fluctuating var is usually caused by hardware issues: overheating, dust buildup, background processes, or outdated drivers. Make sure your PC stays cool, no updates are running, and all resource-heavy programs are closed.
To reduce var, adjust your graphics settings like the pros. Lower effects, shadows, and anti-aliasing — especially if you use custom CS2 crosshairs. You can also use CS2 configs with commands like:
fps_max 289
— locks FPSmat_queue_mode -2
— manages multithreadingcl_forcepreload 1
— preloads textures before the round starts
If var keeps jumping, check your system for overheating and update drivers.
