Hello Plexians,

We have finally added HDR tone mapping support for compatible Intel iGPUs on Windows platforms, and could use your help testing it out before we add it to an official release! Unfortunately Intel drivers only support tone mapping for the following GPUs: TGL (Tiger Lake), DG1 (Intel® Iris® Xe MAX graphics), RKL (Rocket Lake), ADL-S (Alder Lake S), ADL-P (Alder Lake P), DG2 (Intel® Arc™ A-Series Graphics), ATSM (Intel® Data Center GPU Flex Series), and All Future platforms…

What changes should I expect?

When HDR tone mapping is enabled and a compatible Intel device is selected then tonemapping should be preformed on the hardware device when appropriate (instead of falling back to a sw transcode). When an incompatible Intel device is selected then a hw transcode is still preformed, however no tone mapping is applied.

What Feedback are we looking for?

1. Do the changes work as intended?

2. Is the behavior for incompatible Intel devices correct? Would you prefer we fallback to sw transcodes so that tone mapping is applied?

Where to get the preview build (Updated 2024/07/19):
