Tired of stuttering, packet loss, and inconsistent FPS in Valorant? You’re not alone. Radiant coach Charlatan has dropped what might be the most complete Valorant optimization guide ever made—and the results speak for themselves. From system tweaks to GPU overhauls, this guide is packed with steps to give you higher FPS, lower input latency, and a smoother gameplay experience across the board.
Here’s a full breakdown of what you need to do if you want to squeeze every drop of performance out of your setup.
✅ Step 1: Preparation & Backups
Before doing anything, create a system restore point and back up your Windows registry. These steps are crucial in case anything goes wrong.
Charlatan also recommends a clean install of Windows 11, although the guide works well on both Windows 10 and 11.
⚙️ Step 2: Install ISA’s Optimization Toolkit
Download Charlatan’s trusted optimization kit via ISA’s Mega link. ISA is a known optimization expert who has worked with pros and esports events—the tools are 100% safe.
This kit includes all the drivers, regedits, tweaks, and programs you’ll use for the rest of the guide.
🎮 Step 3: Uninstall & Reinstall Your GPU Drivers (Nvidia & AMD)
Nvidia Users:
- Use Display Driver Uninstaller (DDU) to clean uninstall.
- Reinstall driver version 546.33 via NV Clean Install.
- Apply expert tweaks in the setup (disable telemetry, HDCP, overlays, etc).
- Run registry optimizations and apply Nvidia Profile Inspector settings tailored for your GPU series.
AMD Users:
- Use DDU and Radeon Software Slimmer to do a clean install.
- Use ISA’s registry tweaks and Adrenalin Software to fine-tune your GPU.
❄️ Step 4: Cool Your GPU with MSI Afterburner
- Enable custom fan control
- Create a diagonal fan curve to keep temps low without sacrificing noise
- Set the app to auto-start with Windows
This dramatically reduces heat-related performance dips.
🧠 Step 5: NVIDIA Control Panel / AMD Adrenalin Settings
For Nvidia:
- Enable “Use advanced 3D settings”
- Adjust digital vibrance to 70–75%
- Set refresh rate to max
- Set no scaling for native res or test true stretched resolution
For AMD:
- Enable Radeon Anti-Lag
- Optimize tessellation & surface format
- Use custom color settings for better visual clarity
💻 Step 6: Lower Input Latency with Process Lasso
- Import Charlatan’s “bore” config
- Set system timer resolution to 0.504 or 0.507 ms
- Optimize Valorant.exe CPU affinity, priority, and I/O
- Run MeasureSleep.exe to verify latency results
🧹 Step 7: Debloat Windows
Whether you’re on Windows 10 or 11:
- Use Windows Debloater GUI to remove useless background apps
- Disable telemetry, uninstall OneDrive, and enable dark mode
- Install latest Visual C++ redistributables and DirectX runtimes
⚡ Step 8: Set Best Power Plan & RAM Optimization
- Import “bore v2” power plan and delete all others
- Apply the RAM-specific registry tweak (based on your GB size)
- Use Geek Uninstaller to fully remove junk programs
🛠️ Step 9: BIOS Tweaks (Expert Users)
- Enable XMP/DOCP profiles
- Disable virtualization & C-states
- Optional: disable e-cores for Intel, X3D mode for Ryzen (if you’re getting stutters)
- Don’t overclock unless you’re confident
🚀 Step 10: Startup & Background Optimization
- Disable startup apps
- Close all secondary monitors and animations
- Turn off Xbox Game Bar
- Enable Game Mode (tested to boost FPS in Valorant)
- Disable in-app overlays like Discord/Nvidia
- Optimize audio devices and sample rates
🌐 Step 11: Network Optimization
- Set Network Buffering to Minimum in Valorant
- Manually configure DNS using the lowest ping (1.1.1.1 or 8.8.8.8)
- Apply registry and adapter settings to optimize packet flow
- Use TCP Optimizer and Ultimate Windows Tweaker
Bonus: Use ExitLag for better routing if you suffer from packet loss or ping spikes. 3-day free trial included!
📉 True Stretched Resolution Setup
Want that CS-style wide model view? Here’s how to do it:
- Create a custom res (e.g., 1568×1080) with a 1.45 aspect ratio
- Apply it via Nvidia Control Panel or AMD Adrenalin
- Set Valorant to Fullscreen Windowed + Fill for best results
Remember: stretched res gives more FPS, but reduces FOV and may affect aim tracking.
🧼 Hardware Tips for Smooth Gameplay
- Clean your PC regularly
- Change thermal paste every 1–2 years
- Use Ethernet, not Wi-Fi
- Disable RGB lights & charge wireless mouse above 50%
- Avoid high polling rates unless your PC can handle it
🎯 Final Results
After applying all steps, Charlatan shows a noticeable improvement:
- FPS increased
- Input latency decreased
- Stuttering and packet loss gone
While you won’t suddenly get 300 extra FPS on a potato PC, this guide maximizes whatever potential your system has.

Frequently Asked Questions about Valorant Optimization
Q: Will this guide boost FPS on low-end PCs?
A: Yes, especially if you haven’t optimized before. It also helps mid/high-end setups reduce latency.
Q: Is it safe to use the ISA optimization files?
A: 100% safe. ISA is a well-known optimizer who works with pros and esports events.
Q: Do I need to clean install Windows for this to work?
A: No, but it’s recommended for the absolute best results.
Q: Does true stretched resolution give a competitive advantage?
A: It can make enemy models wider, but you’ll lose FOV and clarity—test and decide based on preference.
Q: Should I use ExitLag?
A: If you suffer from high ping or packet loss, it can help—but results vary per user.
Q: Can I break my PC by doing this?
A: No, not if you follow the instructions and create restore points. All steps are reversible.
