Reinstalling is quick, resolves corrupted driver files and most importantly, re-registers Nvidia services required for Ansel and other tools to work properly.

Method 2: Update to Latest Nvidia Game Ready Driver

Recent Game Ready drivers contain fixes specifically aimed at improving compatibility with tools in certain games. Updating can potentially resolve your issues.

To update, simply:

In GeForce Experience, go to Drivers and click Download on the latest Game Ready Driver.
Once downloaded, select Express or Custom install via the on-screen instructions.
Restart your machine when done and test games again.

For example, the June 14, 2022 Game Ready Driver mentions fixing issues with filters in CS:GO – so updating may help in this case if you‘re on an older driver.

Method 3: Enable Nvidia Experimental Features

Enabling Nvidia beta features unlocks additional compatibility tweaks in drivers that may resolve your issues in certain games.

To enable experimental features:

In GeForce Experience, click the settings icon beside your profile.
In the General tab, check the box for "Enable Experimental Features".
Click Apply to save changes.
Restart your computer for changes to take effect.

Early access to experimental driver capabilities may add support for tools in your games.

Method 4: Rollback to an Older Stable Nvidia Driver

If this error started happening after a recent driver update, rolling back to a proven older driver may help.

Follow these steps:

Visit Nvidia‘s drivers page here.
Enter your Nvidia GPU model and operating system details.
Choose a stable driver from 6-12 months ago, avoiding any beta releases.
Download and cleanly install the older driver.
Restart your PC when done.
Test if the error persists in affected games.

The older driver likely does not include the regression or compatibility issues introduced in newer versions. Worth a shot if latest drivers are causing grief!

Method 5: Modify Game Config Files

You can try adding or tweaking certain game config settings to forcibly enable Nvidia tools compatibility.

For Valorant, add these lines to GameUserSettings.ini:

[SystemSettings]  
NVIDIAHighlights=1

[/Script/Valorant.ValorantGameUserSettings]
bEnableNvidiaReflex=True

For CS:GO, add:

net_client_steamdatagram_enable_override -1

Save config files after editing and make them read-only. The config tweaks help circumvent any disabled options for Nvidia tools in-game.

Method 6: Verify Integrity of Game Files

Corrupted or missing game files can prevent Nvidia binaries from hooking cleanly into games, producing errors.

You can verify and restore proper game files as follows:

For Steam games:

Right click game in your Library > Properties > Local Files > Verify Integrity of Game Files.
Steam will automatically scan files and re-download any missing or corrupted ones.

For other games:

Reinstall the game cleanly to overwrite any corrupted files.
Or run the Verify option in the game‘s launcher to check files.

This rules out file corruption as the culprit.

Method 7: Perform a Clean Reinstall of Your GPU Driver

Rather than a simple reinstall, doing a full clean wipe of existing Nvidia drivers using Display Driver Uninstaller (DDU) and reinstalling fresh may fix stubborn issues.

Follow these DDU steps:

Download Display Driver Uninstaller from guru3d.com.
Save and close any open programs. Press Win + R and input "msconfig" to safe boot into Windows.
Run DDU. Select Clean and Restart when prompted to fully remove Nvidia driver.
Upon restart, download and install the latest Nvidia driver cleanly.
Test affected games again.

DDU eliminates any trace of the old driver before reinstalling fresh. Worth a shot for stubborn errors!

Method 8: Update Windows and DirectX

Outdated Windows system files or DirectX could potentially disrupt integration between games and Nvidia tools.

Update to latest versions:

For Windows:

Go to Start > Settings > Update & Security > Windows Update.
Install all available system updates.

For DirectX:

Get the latest DirectX end-user runtime from Microsoft‘s website.
Install it and override existing files when prompted.

This rules out dependency issues from outdated components.

Method 9: Adjust Nvidia Control Panel GPU Settings

Try tweaking GPU configuration options like:

Set PhysX processor to run on your GPU instead of CPU.
Disable GPU acceleration of PhysX if enabled.
Enable/disable SLI rendering mode if using multiple Nvidia GPUs.
Switch PCI-Express slot generation speed.
Adjust power management mode to Prefer Maximum Performance.

Tweaking such options may potentially resolve configuration quirks causing this error.

Method 10: Clean Install Windows as a Last Resort

If you‘ve exhausted all other options, consider clean installing Windows as a final fix:

Backup critical data and remove extra hardware if possible.
Boot into recovery options and access advanced startup.
Choose to reinstall Windows, deleting all files and partitions.
Reinstall chipset, GPU and other drivers once Windows is up.

This completely eliminates any corrupted OS files or driver issues that may be causing Nvidia tools compatibility problems in affected games. Saves you future troubleshooting headaches too when starting from a clean slate!
