Why Is My FPS Low?
Identify the root causes of frame drops, micro-stutters, and low GPU utilization with actionable step-by-step solutions.
Select Your Primary In-Game Symptom
Single-Channel Memory Configuration
Low 1% FPS and severe micro-stutters during combat or when turning the camera.
Using 1 stick of RAM cuts memory bandwidth in half. In CPU-heavy games (Valorant, CS2, Warzone), the CPU starves for data.
Install a matching second RAM stick to enable dual-channel bandwidth (+20% to +35% 1% low improvement).
VRAM Buffer Oversubscription
Smooth 60+ FPS initially, then sudden plunge to 15-20 FPS after 10 minutes of play.
The game has filled your GPU VRAM buffer and is paging textures over the PCIe bus into system RAM.
Lower Texture Quality from Ultra to High/Medium or disable Ray Tracing to fit within your VRAM limit.
CPU Thermal Throttling
FPS drops after 5-10 minutes of heavy gaming with fluctuating clock speeds.
CPU core temperatures exceed 90-95°C, causing the processor to downclock to protect hardware.
Check CPU cooler mounting pressure, replace thermal paste, or adjust case fan airflow curves.
Hidden VSync / Refresh Rate Half-Cap
FPS is rigidly locked at exactly 30, 60, or 72 FPS and will not budge.
Double-buffered VSync drops frame rate to exactly half your refresh rate if you drop a single frame.
Enable G-Sync/FreeSync in your GPU control panel and use Triple Buffering or Reflex Fast VSync.
Background Process CPU Contention
High CPU usage (90%+) with stutter spikes and audio crackling.
Background screen recorders, hardware monitors (RGB software), or antivirus scanning during gameplay.
Close unnecessary tray apps and set game process priority to "High" in Task Manager.
Windows Power Saver Plan Active
CPU clock speeds stay at base frequencies (2.5 GHz) instead of boosting (4.4+ GHz).
Windows is set to "Power Saver" mode instead of "Balanced" or "High Performance".
Switch to "Balanced" or "Ultimate Performance" in Windows Power Options.
