HDR/OLED displays

Paul

I am curious who here runs WSV3 first-gen/would run WSV3 Tactical Mesoanalyst on an OLED HDR monitor.

I am planning special rendering abilities for true hardware HDR display and some initial experiments on a Lenovo Yoga Slim 7x are incredible, even though I would recommend at least Intel Iris Xe embedded graphics.

The novel hardware-level HDR brightness that can be unlocked only by specialized video formats/display applications and certain modern games is an untapped potential for weather visualization, another angle I insist to fully and newly exploit for maximum tactical mesoanalyst human-perceptive value, which is a lot, since the entire graphics style and philosophy of the new engine is based on efficient perception based on contrast and informational density, and larger dynamic range can convey more information at lower absolute brightness levels or better graphics/information at the same brightness levels, which plays straight into the power use vs information delivery optimization philosophy central to WSV3 Tactical's design.

This is something you have to see in person on an actual HDR display because JPGs and PNGs are SDR and this is only a thing with actual physical hardware.

I have developed an application this summer for my own internal usage, but TempoQuest will possibly commercialize soon, which actually converts your entire live desktop into an HDR enhanced display with full interactivity with arbitrary desktop apps, which is an incredible optimization for outdoor sun laptop use (the Yoga Slim I mentioned unlocks up to 1000 nits brightness only with HDR content - currently limited to certain video formats and video games) and also makes low-light dark room usage, such as laptop in bed, way better on the eyes and far more beautiful when you are working with dark mode text editing like coding - it pulls off a bigger dark/white text contrast at lower brightness levels - there's a whole circadian, health, sleep, and work productivity angle for this, and I have lamented the fact a revolutionary side-product has come out of WSV3 Tactical development but I don't have much time to release a secondary product right now.

But WSV3 Tactical absolutely must deliver the same exploitation of dramatic HDR display contrast and bright highlights for the realtime weather visualization. It is funny there is consumer hardware in 2025 that makes this an actual thing, and accessible with D3D12 swapchain formats, because there is a whole story to tell about how Halo 3 (2007) inspires WSV3 Tactical 2025, which was famous in the day for its HDR lighting algorithm on the Xbox 360 hardware. Now the GPUs on PCs support it, and some displays (the higher end OLEDs) have support for actual HDR display, not just a rendering backbuffer format but actually unlocking higher luminosity/physical contrast.

Paul I am currently using an "Asus ROG Swift OLED PG32UCDM" monitor, which has the HDR capability and runs at 4K, 240 FPS. I would highly value the ability to have HDR graphics (even in 120 Hz / 120 FPS).

Suburbazine

I do, I run it on a 15" 4k OLED HDR on my Lenovo P1 Xeon. The screen only bursts to 600nits and averages 400nits though, so peak brightness is limited compared to high-drive OLED monitors you find on some standalone desktop applications.

True HDR content is a huge improvement over SDR content we're all used to. I have even remastered some movies into HDR just to take advantage of the contrast available in the master recordings.

Paul

Suburbazine I will max-out what that monitor can deliver. Especially if its 120hz. 120fps is the new baseline expected experience, however at 4k would usually require better than integrated graphics.

I'll be likely using my macbook pro with Apple XDR display, but with an old secondary LED dell monitor from 2016. Eventually I'll upgrade to a HDR/OLED display as a secondary monitor.

Paul

MeteoLatvia That is going to be incredible. Let's hope you have a GPU that can run a single tight, optimized compute shader pass for full-scene multi-parameter geospatial raster deferred rendered scene at 240fps at 4k - integrated graphics even in 2025 will not achieve this even with the most efficient possible renderer, given the pure mathematics of the texture read bandwidth, but I imagine such a powerhouse gaming monitor is not being driven by an iGPU.

Paul Luckily, just a 2 weeks ago I got a new PC (mainly for my work at TV, but also as a multimedia team member in my university) just a few weeks ago with NVIDIA GeForce RTX 5090 GPU (32 gb, GDDR7, 512bit), with 128 GB of RAM and Intel Core i9-14900 (24 cores). Should this be enough to get 240fps at 4k on WSV3 Tactical?

JPWX

So I have a 36 inch HP Envy Curved with HDR capability. However, it's set at 60Hz and can't be adjusted. I have a 2nd monitor that can be adjusted to max out at 75Hz. I haven't ran WSV3 on it, but given this, I am curious if this might lead to issues once I put the new version of WSV3 on.

Paul

JPWX I would imagine you're very likely to get full 60fps out of that, as long as it's not some 4K resolution monitor with only integrated graphics. 60fps rendering is half the GPU work as 120fps, the development optimization target.

MeteoLatvia With a powerhouse like that, I would hope so. Some quick math, ((38402160)240)/((28801800)120) = 3.2. So your high-end discrete RTX 5090 GPU only has to do 3.2x the rendering work as measured by total pixels per second than my 2023 Intel Iris Xe integrated laptop graphics (non-gaming laptop) is doing to fill my 2880x1800 @ 120fps OLED ASUS Zenbook monitor.

Looking at UserBenchmark, your card is probably 1000 - 3000 percent faster than my development laptop iGPU, so it would appear that your experience even at 4K/240fps should be more GPU performant (less frame time) than the baseline optimized 120fps @ 2880x1800 experience on my dev laptop, where GPU frame time at fullscreen is currently at 4.9ms.

I certainly look forward to seeing how it runs on that powerhouse and what the frame times are.
