Do You Lose FPS with HDR?

With the rise of High Dynamic Range (HDR) in gaming, many players wonder if they will sacrifice Frame Per Second (FPS) performance when enabling HDR on their console or PC. In this article, we will explore the impact of HDR on FPS and shed light on the situation.

Do You Lose FPS with HDR? The Simple Answer

In short, no, enabling HDR does not directly decrease FPS performance. HDR rendering works in tandem with your FPS settings, and it primarily affects the visual presentation, not the performance itself. You can still maintain silky smooth gameplay while enjoying enhanced visuals.

But… There Are Some Factors to Consider

While HDR by itself does not directly reduce FPS, there are instances where it might have a slight impact on performance, such as:

• HDR Rendering Time: HDR rendering can add milliseconds to the rendering process. This is due to the increased processing requirements needed to handle the wider color gamut, contrast range, and higher bitrates associated with HDR. As a result, FPS can be slightly affected in heavy-demanding games.

Factors That Affect HDR Performance

To provide more clarity, here are factors that can influence the effect of HDR on FPS:

Case Studies and Example

To illustrate this relationship, let’s look at some real-world examples:

• LG 27UK850-W – This 27-inch IPS monitor has a reported max refresh rate of 75Hz, but downscales to 48Hz for HDR.
• Asus PG27UQ – This 27-inch gaming monitor can maintain 120Hz at 4K, but drops to 60Hz when engaging HDR.

Keep in mind that these specific situations might not be representative of all HDR-enabled displays and GPUs.

How 1440p vs 4K Affects HDR Performance

In this chart, we can see a comparison of FPS at 1440p (2688×1520) and 4K (3840×2160) resolutions, along with the effect of enabling HDR:

As you can see, 1440p experiences a more manageable FPS drop, while 4K and HDR combination can be quite demanding.

Conclusion

In summary, HDR and FPS are not inherently exclusive. While HDR might not directly decrease FPS, several factors can influence performance:

• HDR rendering time
• GPU Power
• Resolution (especially 4K)
• Monitor limitations

By understanding these interdependencies, you can adapt your gaming setup and choices to ensure the best overall experience.

Bonus Section: What About Other Settings?

In this annex, we’ll quickly review the impact of other performance-related settings on FPS, keeping in mind that:

• Anti-Aliasing (e.g., SMAA, TXAA) can consume an additional 5-20% of GPU power
• Motion Blur Reduction (e.g., TAA, DRT) might reduce performance up to 10-30%
• Frame Rate Cap can help regulate the maximum FPS for better optimization

These settings should not have a significant impact on FPS, but some individual experiences may vary depending on specific games and configurations.
