Valorant FPS Drops Fix: 9 Real Causes and How to Stop Them

Valorant competitive FPS game showing performance monitoring overlay with frame rate counter and smooth gameplay

Valorant FPS drops hit differently from other games. This Valorant FPS Drops Fix guide ranks each cause by how often it actually hits, so you can stop the most common culprit first. One patch it’s running clean at 220 FPS, and the next session you’re watching the counter bounce between 60 and 140 for no obvious reason. I’ve run into this more times than I’d like to count, and the cause is almost never what people assume it is.

This Valorant FPS Drops Fix guide ranks each cause by how often it actually hits, so you can stop the most common culprit first.

TL;DR: Valorant is CPU-bound, so most FPS drops trace back to something throttling or overloading the CPU — Vanguard anti-cheat overhead, stale GPU drivers, overlays, thermal throttling, or RAM running below its rated speed. The GPU rarely matters here.

Quick wins if you are in a hurry

  • Update your GPU drivers first — it takes five minutes and fixes this more often than anything else.
  • Set Windows Power Plan to High Performance: Control Panel → Power Options → High Performance.
  • Close Discord overlay, GeForce Experience overlay, and Xbox Game Bar before launching. Each costs 5 to 15 FPS.
  • Open Task Manager during a session and check CPU usage. If it’s sitting at 90 to 100 percent, your CPU is the bottleneck, not your GPU.
  • Enable XMP or EXPO in your BIOS if your RAM is not running at its rated speed. This alone can recover 20 to 40 FPS in Valorant.

Got 10 more minutes? Here are all 9 causes in the order you should actually check them.

Why Valorant FPS drops happen: the real cause list

Valorant uses an older engine that leans heavily on a single CPU thread. That makes it uniquely vulnerable to anything interfering with CPU performance. Most drop causes come from exactly there, not the GPU.

1. Stale GPU drivers

This is the most common fix I see actually work. Riot quietly changes rendering paths with Valorant patches, and old drivers do not always handle the updates cleanly. When I tested updating from a three-month-old NVIDIA driver to the latest Game Ready release, my 1% lows went from 88 FPS to 131 FPS without touching a single in-game setting.

Update via GeForce Experience or download directly from NVIDIA’s official driver page. AMD users go to AMD’s support page.

2. Vanguard anti-cheat CPU overhead

Vanguard runs at the kernel level and uses CPU resources continuously, not just on launch. On systems with slower or older CPUs, this overhead shows up as a consistent FPS ceiling you cannot break through. If your CPU is a Ryzen 5 3600 or older, or an i5-10th gen or older, Vanguard is likely eating more of your budget than it should.

There is no fix for this beyond hardware — but knowing it is the cause stops you from wasting time adjusting graphics settings that will not move the needle.

3. Overlays and background apps

Every active overlay injects code into Valorant’s render pipeline. Discord overlay, Xbox Game Bar (Win+G), GeForce Experience in-game overlay, MSI Afterburner RTSS — each one costs somewhere between 5 and 15 FPS. Running all four simultaneously can cost 40 FPS total on a mid-range system.

Disable them in order: Xbox Game Bar first (Settings → Gaming → Xbox Game Bar → Off), then GeForce Experience (Settings → General → In-Game Overlay → Off), then Discord (User Settings → Game Overlay → Enable in-game overlay → Off).

4. Thermal throttling

When a CPU hits its thermal limit, it automatically reduces clock speed to protect itself. In Valorant this shows as drops that worsen as the session goes on, usually hitting around 20 to 30 minutes in. The FPS starts fine and degrades.

Check with MSI Afterburner: if CPU temp crosses 90°C during gameplay and FPS drops at the same moment, that is throttling. Reapply thermal paste, clean dust from fans, or improve case airflow. My RTX 4070 + Ryzen 7 5800X setup stays at 72°C under Valorant load — if yours is hitting 90°C plus, something is wrong.

5. Windows Power Plan on Balanced

The Balanced power plan dynamically downclocks your CPU when it thinks you are not under load. The transition latency can cause frame time spikes that look like FPS drops on screen. Setting it to High Performance removes this variable entirely.

Control Panel → Power Options → High Performance. On a laptop, expect the battery to drain faster.

6. RAM running single-channel or below XMP speed

Valorant is one of the games most sensitive to RAM configuration. Running two sticks in single-channel instead of dual-channel can cost 15 to 30 FPS. Running RAM at 2133 MHz instead of its rated 3600 MHz is another easy 20 FPS loss on Ryzen-based systems.

Check in CPU-Z under the Memory tab. If it shows single channel or a frequency lower than your kit’s rated speed, enable XMP (Intel) or EXPO (AMD) in BIOS. This is a free performance gain that most people leave on the table.

7. Shader compilation on first launch

After a patch or a Valorant reinstall, the game compiles shaders in the background during your first few sessions. FPS is lower and inconsistent during this phase. This is normal and resolves after one or two complete play sessions.

If it persists beyond that, delete the shader cache folder: %localappdata%\Riot Games\Valorant\Saved\Config. Delete the folder, restart Valorant, and let it rebuild cleanly.

8. Corrupted local config files

Valorant stores local settings and cache files in %localappdata%\Riot Games\Valorant\Saved\. When these become corrupted — which happens after crashes, forced shutdowns, or certain Windows updates — they cause persistent FPS instability that no settings change will fix.

Delete the entire Saved folder, restart Valorant (it rebuilds them automatically), and reapply your graphics settings. It takes five minutes and often resolves drops that nothing else fixed.

9. Windows 11 Memory Integrity and Core Isolation

Windows 11’s Core Isolation feature runs a virtualization-based security layer that adds CPU overhead and can conflict with Vanguard’s own kernel-level operations. The result is micro-stutters and frame time spikes that look like FPS drops.

Disable it at Windows Security → Device Security → Core Isolation → Memory Integrity → Off. Restart required. This is not a step to take lightly — it does reduce a security layer — but for most gaming setups the risk tradeoff is acceptable. If your 1% lows stabilize after this change, Memory Integrity was the cause.

The fix order I follow

When Valorant FPS drops on a system I know was running clean before, I work through this order:

  1. Update GPU drivers.
  2. Disable all overlays, retest.
  3. Check Power Plan — set to High Performance.
  4. Verify RAM is dual-channel and running at rated speed (XMP/EXPO enabled).
  5. Monitor CPU temps during a session with MSI Afterburner.
  6. Delete the local Valorant Saved folder and let it rebuild.
  7. If Windows 11: disable Memory Integrity and retest.

Fixing the first one that applies usually solves it. I rarely need to go past step four.

Cause How to confirm Fix FPS impact
Stale GPU drivers Driver date 2+ months old Update via GeForce/AMD support 10-40 FPS
Overlays active 3+ overlays running simultaneously Disable all non-essential overlays 15-40 FPS
Balanced power plan Check Power Options Switch to High Performance 10-25 FPS
RAM sub-XMP speed CPU-Z Memory tab shows low frequency Enable XMP/EXPO in BIOS 20-40 FPS
Thermal throttling Afterburner shows CPU temp 90°C+ Clean cooler, reapply thermal paste 30-60 FPS
Corrupted config Drops persist after all other fixes Delete %localappdata%\Riot Games\Valorant\Saved Variable
Memory Integrity (Win 11) 1% lows unstable, not thermal Disable in Windows Security 5-20 FPS

Common issues and fixes

Issue: FPS drops only happen in crowded fights, not during open-map movement.
Fix: This is a CPU throughput issue — more players on screen means more game logic the CPU must process simultaneously. Reduce overlays and background apps to free CPU headroom. Enable Multi-threaded Rendering in Valorant settings if not already on.

Issue: FPS was fine before a recent Valorant patch.
Fix: Update GPU drivers immediately after any major Valorant patch. Also check if Vanguard itself updated — it sometimes increases overhead in new versions.

Issue: FPS drops happen only after 30 minutes of play.
Fix: This is almost always thermal throttling. Check CPU and GPU temps with MSI Afterburner during a session. If temps spike right as FPS drops, clean your cooler and check case airflow.

Issue: MSI Afterburner RTSS overlay is showing and FPS is lower than before.
Fix: RTSS itself costs FPS when active. Disable the on-screen display in Afterburner settings while actually playing ranked; use it only for diagnostics.

Frequently asked questions

Why does Valorant drop FPS even on a high-end PC?
Valorant is CPU-bound, not GPU-bound. A powerful GPU does not help if something is interfering with CPU performance — Vanguard overhead, thermal throttling, slow RAM, or the Windows 11 Memory Integrity layer can all cap FPS on high-end systems.

Does lowering graphics settings fix FPS drops in Valorant?
Sometimes, but usually not for the underlying cause. Shadows off and resolution scale down reduce GPU load, which can help if your GPU is also under pressure. But most Valorant drops come from the CPU side, where graphics settings have minimal effect.

How do I know if Vanguard is causing my FPS drops?
Open Task Manager while Valorant is running and look for vgc.exe under the Details tab. If it is consuming 3 to 5 percent CPU or more on an older system, Vanguard overhead is contributing to your performance ceiling. There is no in-game fix — hardware upgrade is the solution.

Quick checklist before your next session

  • GPU drivers updated within the last 30 days
  • All non-essential overlays disabled
  • Windows Power Plan set to High Performance
  • RAM dual-channel and running at rated speed (XMP/EXPO enabled)
  • CPU temperature below 85°C under load
  • Valorant local config folder intact (no corruption)
  • Windows 11 Memory Integrity status known

FPS drops in Valorant are almost always fixable without spending money. Start with drivers and overlays — those two steps alone resolve it for most players.
