ValorantFPS drops and low FPS

Fix Valorant FPS Drops and Low FPS on Windows 11

Valorant is built to run on modest hardware, so sustained low FPS usually points at the Windows side rather than the engine: CPU clocks dropping, background processes stealing time slices, or a GPU parked in a power-saving state. Riot Vanguard also loads as a kernel driver at boot and stays resident whether or not the game is open, so the rest of your startup stack has to share the same CPU.

Common symptoms

FPS sits far below what your hardware should deliver even on the Low preset.
The frame rate collapses during spike plants, smokes and ultimates with heavy particles.
FPS is normal in the practice range but drops in a live match.
Performance is fine right after a reboot and degrades over a long session.

Likely causes

Windows power plan and CPU core parking capping sustained clocks.
Chrome, Discord, Spotify and launcher clients running with hardware acceleration during matches.
A stale or partially installed GPU driver after a Windows feature update.
A laptop stuck on a battery profile, or thermal throttling once the CPU package hits its limit.

Safe fix order

1.Watch temperatures and clocks with HWiNFO during a real match: a CPU or GPU that drops clocks under load is a thermal or power problem, not a software one.
2.Set a high-performance power plan, turn Windows Game Mode on, and make sure a laptop is running on the plugged-in profile.
3.Close Discord calls and browser tabs or disable their hardware acceleration, and switch off Game Bar, background recording and overlays you do not use.
4.Cap Valorant just under your refresh rate with Limit FPS Always, enable NVIDIA Reflex in the video settings, and leave the cap on in menus too.
5.If FPS is still low, reinstall the GPU driver cleanly with DDU and keep at least 15 percent of the system SSD free so Windows can cache and page normally.

Where DRX fits

DRX Optimizer handles the Windows side only: reversible power, service and Game Bar tweaks, safe cleanup, per-game Game Mode, and a status check after reboot. It never edits Valorant video settings or interferes with Vanguard.

FAQ

Is using an optimizer safe with Riot Vanguard?

DRX does not inject into Valorant or modify game files, and Vanguard folders are excluded from cleanup. Leave Core Isolation and VBS enabled, because Vanguard expects the default Windows security configuration.

Why does Valorant only drop FPS in matches?

A live match adds network traffic, nine other players, agent abilities and anti-cheat activity on top of the render load. The practice range is a much lighter scene and hides CPU bottlenecks.

Does lowering graphics settings help if I am CPU bound?

Barely. If GPU usage stays well below full while FPS is low, the limit is CPU or memory, so clocks, RAM speed and background load matter far more than texture quality.
