Weird brightness glitch with rectangular artifact on RTX 4060 worsens at 60 FPS, started suddenly

Title: Troubleshooting Sudden Brightness Artifacts and Performance Issues on RTX 4060

Introduction

Many gamers rely on their GPU’s performance and visual fidelity to enjoy seamless gameplay, but occasional glitches can disrupt the experience. Recently, some NVIDIA RTX 4060 users have reported encountering unexpected visual artifacts—specifically, a rectangular brightness glitch—that worsens under certain conditions. This article explores potential causes, troubleshooting steps, and solutions to address this issue effectively.

Understanding the Issue

Affected users have observed a distinct rectangular brightness artifact appearing intermittently during gameplay. The anomaly is subtle in recorded footage but becomes more noticeable during active gameplay sessions. Notably, the glitch:

Appears suddenly without prior indication
Is visible across multiple games, not limited to titles like Left 4 Dead 2
Worsens when FPS is capped at 60, compared to unlimited FPS
Has been resolved temporarily by enabling V-Sync, although this introduces increased input lag

Initial observations suggest that the glitch may be linked to rendering or synchronization settings, but the exact cause remains uncertain.

Possible Causes and Troubleshooting Steps

Graphics Driver Compatibility and Updates

Outdated or corrupted graphics drivers can cause rendering anomalies. Ensure that your GPU drivers are up to date:

Visit the NVIDIA Driver Download page
Download and install the latest stable drivers for the RTX 4060
Perform a clean installation to remove potential remnants of previous driver versions
Game and Application Settings

Since the problem appears more prominently at 60 FPS, check your in-game and system settings:

Verify V-Sync status: Enabling V-Sync tends to mitigate the artifact, but be aware of added input lag
Experiment with different frame rate caps or disabling them to observe changes
Adjust resolution and rendering settings to identify if specific configurations trigger the glitch
Monitor and Hardware Checks
Confirm that your monitor’s refresh rate and resolution match your in-game settings
Test the GPU in different games or benchmarks to determine if the issue is consistent
Use tools like NVIDIA’s GPU monitoring software to check for overheating or performance throttling
System Stability and Background Processes
Ensure your system is free from background applications that could interfere with GPU rendering
Run hardware diagnostics to rule out potential issues with the GPU or other components
Rollback and Test
