Introduction

In the world of benchmarking, it's always exciting to stumble upon something that offers better performance, especially if you're utilizing older hardware. One particular feature that intrigued me recently is the "Negative Load Bias" setting in the Nvidia control panel. A viewer requested a test to compare the performance between the default "Allow" setting and the alternative "Clamp" setting. This setting, found under Texture Filtering in the manage 3D settings, supposedly affects both image quality and performance. In this article, we will delve into this topic and explore the results of my testing.

Understanding Negative Load Bias

Negative Load Bias is a parameter used in some applications to enhance texture filtering. It works by sharpening the stationary image but introducing aliasing when there is motion in the scene. The Nvidia control panel offers two options for this setting: "Allow" and "Clamp". The default setting is "Allow", which promises higher performance, while "Clamp" is said to improve image quality when anisotropic filtering is enabled.

Texture Filtering in Nvidia Control Panel

Before we dive into the performance comparison, let's take a moment to understand where the Negative Load Bias setting is located in the Nvidia control panel. You can access it by navigating to the manage 3D settings and then selecting Texture Filtering. Within Texture Filtering, you will find the option for Negative Load Bias.

The Default Setting: Allow

By default, the Negative Load Bias setting is configured as "Allow". This means that all the images on the screen, excluding movements, may appear slightly blurry. However, it is claimed that this setting provides better overall performance.

The Alternative Setting: Clamp

On the other HAND, the alternative setting for Negative Load Bias is "Clamp". When set to "Clamp", image quality is expected to improve, but at the cost of performance. This setting is recommended for users who prioritize image quality over FPS.

Performance Comparison: Allow vs Clamp

To determine the impact of Negative Load Bias on performance, I conducted extensive testing on nine different games. All games were tested at medium settings using driver 5.31.18. Surprisingly, the results were not what I had expected.

Impact on FPS and Image Quality

With Negative Load Bias set to "Allow", the average FPS over the nine games was 70.9. However, when switched to "Clamp", the average FPS increased to 71.37. These figures clearly indicate that the "Clamp" setting delivers slightly better performance.

Games with Shitty Anti-Aliasing

In addition to improved FPS, the "Clamp" setting also enhances image quality, particularly in games with subpar anti-aliasing. Games such as Red Dead Redemption, Horizon Zero DAWN, and Spider-Man Remastered exhibit much better image quality with the "Clamp" setting enabled.

Stability Analysis

When assessing stability, I observed that the "Clamp" setting yields higher one percent lows compared to the "Allow" setting. Dividing the one percent lows by the average FPS, I found that the stability score for the "Clamp" setting was 65.21, slightly higher than the score of 63.51 for the "Allow" setting.

Conclusion

In conclusion, my extensive testing revealed that the Negative Load Bias setting of "Clamp" in the Nvidia control panel offers slight improvements in both average FPS and image quality compared to the default "Allow" setting. Gamers who Seek a better balance between performance and image quality should consider making this adjustment. However, it's important to note that the impact may vary depending on the specific hardware configuration and game settings. Overall, it is worth exploring this setting further to maximize the gaming experience.
