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 modest to substantial on some cards; they do not establish a current-generation Nvidia average. Native HDR built into a game is also different from Nvidia’s RTX HDR feature, which adds GPU processing to SDR games.
How much performance can HDR cost on Nvidia GPUs?
There is no single HDR penalty that applies to every Nvidia card or game. The clearest multi-game comparisons available here date to 2018, when Pascal- and Turing-era GPUs were tested. Treat these numbers as historical results for their stated setups, not as predictions for current GPUs.
ComputerBase: GTX 1080 results at 4K
In ComputerBase’s 2018 4K test, enabling HDR lowered the GeForce GTX 1080’s frame rate by about 10% on average across the tested games. Destiny 2 was a larger outlier, with a roughly 20% loss. In one specific Call of Duty: WWII run, the GTX 1080 averaged 51.0 FPS in SDR and 46.1 FPS in HDR. ComputerBase also measured about a 2% average loss for the Radeon RX Vega 64 in its test suite, but said it did not know why the Nvidia loss was greater. That comparison is context for the test, not evidence about current Nvidia hardware. ComputerBase’s results and interpretation are published in German.
PCWorld: output format changed the result
PCWorld’s 2018 tests used an Acer Predator X27 at 120 Hz and compared 8-bit RGB with 10-bit YCbCr 4:2:2. In the tested 10-bit YCbCr 4:2:2 mode, average performance across four HDR games was lower by 5.89% on the RTX 2080, 10.38% on the GTX 1080 Ti, and 10.24% on the RTX 2080 Ti. PCWorld said the losses were smaller with 8-bit RGB. YCbCr 4:2:2 can also make desktop text look worse than RGB, so the format is not a cost-free workaround. These results show that Turing cards still had measurable overhead in that particular configuration; they do not show that newer architecture always performs the same way. PCWorld’s review describes the setup.

Why results vary by game and GPU generation
Tom’s Hardware described HDR processing as an additional pipeline burden on Pascal, while Turing integrated HDR processing and tone mapping into its pipeline. Even within its Turing-era testing, outcomes differed: in Destiny 2, the RTX 2080 Ti, RTX 2080, and GTX 1080 Ti delivered 93–94% of their respective SDR frame rates. In Battlefield 1, HDR reduced some stuttering early in a run and improved 99th-percentile results, even though the GTX 1080 Ti’s average frame rate was slightly behind SDR. That is why average FPS alone may not capture how smooth a game feels. Tom’s Hardware’s RTX 2080 review covers the pipeline discussion and game results.
Native game HDR and RTX HDR are different
Native HDR
A game with native HDR renders or outputs an HDR presentation through its own HDR support. The 2018 GPU comparisons above concern game HDR and associated output configurations. Their measurements should be understood in the context of the games, graphics cards, and display formats tested.

RTX HDR for SDR games
Nvidia’s RTX HDR instead applies an HDR effect to a game that outputs SDR. A July 2026 analysis describes it as processing each SDR frame through a neural network running on Nvidia Tensor cores to infer an HDR presentation. The analysis reports a significant performance cost in Kena: Bridge of Spirits, but covers only that one game and does not provide a controlled cross-GPU average. It is not a basis for assigning a general percentage penalty to RTX HDR. The July 2026 RTX HDR analysis gives its scope and findings.
What to check if HDR looks wrong
Dim, washed-out, or oddly colored output is a presentation problem, not proof of a particular frame-rate penalty. NVIDIA says Microsoft recommends enabling Windows HDR before playing HDR games or video. NVIDIA also warns that some TVs and computer displays do not reproduce HDR colors and luminance accurately; on such a display, SDR may look better.

NVIDIA describes occasional mismatches between Windows HDR and a game’s HDR setting: enabling HDR in a game while Windows HDR is off can produce incorrect colors, and some Vulkan games can appear too dim when the two settings disagree. If you see those symptoms, make the Windows HDR state and the in-game HDR state match. This recommendation addresses image presentation; it does not establish that changing the setting removes rendering overhead. NVIDIA’s HDR guidance explains these cases.
How to check the impact on your own setup
A controlled comparison is more useful than applying an old average to a different GPU or game. Compare the same scene or built-in benchmark, changing only the HDR mode.

- Set a repeatable scene or benchmark and note the game’s resolution, refresh rate, graphics settings, GPU driver, and display connection/output format.
- Run the scene with Windows HDR and the game’s native HDR both off, then repeat it with both on. Keep the other settings unchanged.
- Repeat each run and record average FPS along with frame-time behavior; a single run can be affected by normal variation or stuttering.
- If you want to measure latency as well, use a consistent tool and method. NVIDIA’s FrameView 1.4 guide describes collecting average frame rate and PC latency in gameplay or built-in benchmarks, and says FrameView works across GPU vendors.
For a separate RTX HDR check, compare the same SDR game scene with RTX HDR off and on; do not treat that result as a measurement of native HDR. Record the feature and game separately so the two workloads are not conflated.

In PCWorld’s 2018 review, Nvidia said: “The Turing GPU architecture improves High Dynamic Range (HDR) gaming performance and input latency using hardware-based compositing, tone mapping, and chroma filtering with HDR surfaces.” This is Nvidia’s description of its architecture, not proof that Turing has no HDR overhead. PCWorld’s and ComputerBase’s measured results show that the outcome still varied with game and output configuration.

Do the old benchmark losses apply to current Nvidia GPUs?
No current-generation multi-game comparison across current drivers, games, displays, and output formats is established by these figures. The 2018 findings are useful evidence that HDR overhead existed on particular older Nvidia setups, but they cannot establish a universal or present-day percentage. The reliable answer for a current system is to measure the specific game and HDR mode you use.
