HDR can reduce frame rates on Nvidia GPUs, but the size of the hit depends on the game, GPU, and display-output format. Historical tests from 2018 found losses ranging from a few percent on average to about 20% in one game; those results do not establish a current-generation Nvidia average. Native game HDR and Nvidia’s RTX HDR feature are also different workloads, so their performance costs should not be treated as interchangeable.
What the benchmark results show
The clearest quantified comparisons available here are from 2018, using Pascal- and Turing-era cards. They show that HDR could cost performance in those test conditions, not that every Nvidia GPU takes the same hit today.
| Source and test | GPU and result | What the figure means |
|---|---|---|
| ComputerBase, 2018, tested games at 4K | GeForce GTX 1080: about 10% lower average frame rate with HDR; about 20% lower in Destiny 2 | The average covers ComputerBase’s tested games; the Destiny 2 result is game-specific. |
| ComputerBase, 2018, Call of Duty: WWII at 4K | GeForce GTX 1080: 51.0 FPS in SDR and 46.1 FPS in HDR | One listed run, not a general Nvidia estimate. |
| PCWorld, 2018, four HDR games on an Acer Predator X27 at 120 Hz | RTX 2080: 5.89% lower average performance; GTX 1080 Ti: 10.38% lower; RTX 2080 Ti: 10.24% lower | These averages were for the tested 10-bit YCbCr 4:2:2 mode. PCWorld reported smaller losses with 8-bit RGB. |
ComputerBase reported about a 2% average loss for the Radeon RX Vega 64 in its tested HDR suite, compared with about 10% for the GTX 1080, and said it did not know why the Nvidia loss was greater. That is context from the same historical test, not a prediction for current Nvidia or AMD hardware.
The output format mattered in PCWorld’s comparison. Its 10-bit YCbCr 4:2:2 mode produced larger losses than 8-bit RGB, but PCWorld noted that YCbCr 4:2:2 can make desktop text look worse outside games. The lower-loss result with 8-bit RGB does not mean every game, display, or setup will behave the same way.

Why the hit can vary
HDR handling is part of the graphics and display pipeline, and the work varies with the game and output configuration. Tom’s Hardware described Pascal’s HDR burden in terms of pipeline processing and said Turing incorporated HDR processing and tone mapping into the pipeline. But that architectural change did not make the cost uniformly disappear: in Tom’s Hardware’s Destiny 2 data, the RTX 2080 Ti, RTX 2080, and GTX 1080 Ti reached 93–94% of their respective SDR frame rates.
Average FPS is not the whole experience, either. In Tom’s Hardware’s Battlefield 1 testing, HDR reduced some early-run stuttering and improved 99th-percentile results, while the GTX 1080 Ti’s average frame rate remained slightly behind SDR. A setting can therefore affect frame pacing and average throughput differently.

NVIDIA described Turing’s approach as improving HDR gaming performance and input latency through hardware-based compositing, tone mapping, and chroma filtering with HDR surfaces. That is the company’s architectural claim, not proof that Turing cards—or newer generations—have no HDR overhead.
Native game HDR is not RTX HDR
Native HDR
Native HDR is the game’s own HDR output path. The 2018 comparisons above concern HDR gaming output in their particular test setups; they should not be generalized to every current game or GPU.

RTX HDR
RTX HDR is a separate Nvidia feature for games that output SDR: it processes each SDR frame to create an HDR presentation. A July 2026 analysis describes it as using a neural network running on Nvidia Tensor cores. That analysis reports significant performance cost in Kena: Bridge of Spirits, but covers only that game and does not provide a controlled cross-GPU average. Treat it as a limited observation, not a universal percentage for RTX HDR.
Check HDR settings if the picture looks wrong
NVIDIA says Microsoft recommends enabling Windows HDR before playing HDR games or video. Its support guidance also warns that some TVs and computer displays do not render HDR colors and luminance accurately; SDR may look better on those displays.

If colors look incorrect or a Vulkan game appears too dim, check that Windows HDR and the game’s HDR setting agree. NVIDIA describes rare state mismatches—for example, a game set to HDR while Windows HDR is off—and recommends matching the two settings when such presentation problems occur. This is display troubleshooting advice; it is not evidence that matching the settings removes rendering overhead.

- Choose one repeatable scene. Use the same section of a game or its built-in benchmark for each run.
- Compare native HDR on and off. Keep resolution, refresh rate, graphics options, and GPU driver constant. Change only the HDR setting being tested.
- Repeat the runs. Repetition helps distinguish a consistent difference from normal run-to-run variation.
- Record more than average FPS. Note frame-time behavior as well. NVIDIA’s FrameView 1.4 User Guide describes collecting average frame rate and PC latency in real gameplay or built-in benchmarks; the guide says FrameView works across GPU vendors.
- Test RTX HDR separately if you use it. Compare its effect independently from native game HDR, since it processes SDR output rather than using the game’s native HDR path.
What these results do—and do not—establish
The historical tests establish that HDR could reduce performance on specific Nvidia cards in specific games and output modes, and that the size of the change varied. They do not establish a current-generation average across modern GPUs, drivers, games, displays, and formats. To answer whether HDR is a heavy hit on your own system, use a controlled comparison on the game and output path you actually play.
