NVIDIA Optimization Guide  ·  2026 Update

Most NVIDIA guides tell you to change settings. This guide tells you to start with the driver. A dirty driver install, a GPU running at the wrong PCIe speed, or a bad slot will cancel out every setting in this guide. Fix those first. Then tune the NVIDIA App.

Do This In The Right Order

Order matters. If you skip straight to NVIDIA App settings without cleaning the driver first, old driver leftovers can still break your FPS and cause stutters. Follow these three steps before changing any settings.

Step 1 — Remove The Old Driver With DDU

Open DDU from the pack. Set device type to GPU and manufacturer to NVIDIA. Click Clean and Restart.

The normal Windows uninstaller leaves behind driver files, registry entries, and old profiles. DDU removes all of that. Stutters, broken settings, and FPS that does not match your hardware often trace back to dirty driver leftovers.

DDU: GPU selected, NVIDIA selected. Click Clean and Restart. Do not install a new driver yet.

1. 1
   Open DDU from the pack

   Extract the zip to your desktop. Open the DDU folder and run the program.

2. 2
   Set GPU and NVIDIA

   Device type = GPU. Manufacturer = NVIDIA. Both dropdowns on the right side of the DDU window.

3. 3
   Click Clean and Restart

   Let the PC restart fully. Do not install a new driver until the PC comes back up. Then open NVCleanstall.

Step 2 — Install A Clean Driver With NVCleanstall

Open NVCleanstall. Pick the driver version you want. The newest driver works for most people. If a specific older driver was more stable for your games, pick it from the list inside NVCleanstall.

NVCleanstall component screen. When it asks about required dependencies, click Yes to continue.

Step 3 — Check GPU-Z Before Changing Any Settings

Open GPU-Z. Find Bus Interface. Click the question mark next to it. Then start the render test so the card wakes up from its idle power state. This shows the real PCIe connection your GPU is running under load.

A card can be fully plugged in and still run at a fraction of its expected speed. If a high-end GPU shows x4 instead of x16, no NVIDIA App setting will fix that. Check the hardware first.

GPU-Z Bus Interface: run the render test first so the card is not in power-save mode. Confirm the lane count matches what your hardware should support.

NVIDIA App — Turn Off What You Do Not Use

Open the NVIDIA App and go to Settings. Turn off Game Filters if you do not use them. Turn off Photo Mode, the overlay, recording, and Instant Replay if you do not need them. Running extra features in the background wastes FPS for no reason.

The most important one: turn off Automatic Game Optimization. You do not want NVIDIA automatically changing settings inside Fortnite, Valorant, or Call of Duty on its own. Also turn off Automatic Driver Downloads so updates happen when you decide, not right before a match.

NVIDIA App — Global Graphics Settings

Go to Graphics, then Global Settings. This is where the key competitive gaming settings live.

NVIDIA App Global Settings. Set Smooth Motion to Off. Keep DLSS overrides on Use Application Settings.

Low Latency Mode and Reflex are not the same thing. If your game has Reflex, use it inside the game settings. Low Latency Mode is the backup for games that do not have Reflex. It has worked on DirectX 12 titles since driver 551.23 in January 2024.

Legacy Settings

Click Show Legacy Settings in the NVIDIA App. For competitive games: turn off FXAA, Anti-Aliasing Transparency, and MFAA. Leave Anisotropic Filtering off and let the game handle it. Set Texture Filtering Quality to High Performance. Keep the global profile simple.

Display Settings — Check Your Refresh Rate

Go to System, then Displays. Make sure your resolution and refresh rate are correct. If you bought a 144 Hz, 240 Hz, 360 Hz, or 500 Hz monitor, confirm NVIDIA and Windows are actually using that rate. Many expensive monitors sit at 60 Hz for months without anyone noticing.

For most setups: native resolution, max refresh rate, No Scaling, scaling device set to Display. If Output Dynamic Range is available, set it to Full so colors do not look washed out.

Windows — Enable HAGS

Open Windows Settings and go to Display, then Graphics, then Change Default Graphics Settings. Turn on Hardware Accelerated GPU Scheduling. Restart your PC. HAGS helps reduce CPU-to-GPU scheduling overhead on modern hardware. Worth enabling and testing.

Quick Checklist

This Only Covers The GPU Layer

This guide does not fix BIOS settings, RAM speed, Windows bloat, game configs, or CPU behavior. NVIDIA is one layer. If your PC still feels choppy or delayed after following this, the problem is probably somewhere else in the stack.
