The issue is that the HDR grading works with ACES 1 mainly. And ACES 1 is available in the 32bit Floating Point mode only - what makes HDR grading very slow. To my opinion impossible on a Laptop today. Even with my 8 core Desktop I have to switch to preview/quaterly to have enough fps for the preview from the timeline if I enable the conversion to rec2020 or rec709.
For me a workaround is that I use the Atomos Sumo or Sumo M as grading monitor.
https://www.atomos.com/sumo19m
I run the Sumo either from my R9 390X or my Decklink 4K Extreme 12 G. The Decklink works only if you have enabled the conversion to rec2020/rec709 in ACES what seems to be a bug in Vegas. But here the good news are that you can use a GPU like the R9 390X if you use the Sumo - simply because you can switch the Sumo to make im adjust the Gamma and Gamut conversion. So either you use the ACES 1 conversion in the Project Settings what will bring down your performance, or you you use the Sumo for the conversion and set it to rec2020/PQ/rec2020. With the later you can run the HDR editing also in the 8bit mode - what is great in terms of performance. And switch the Project Settings for the final Rendering only. And you have a great preview too - because you can set the Sumo to vlog/v-Gamut/rec2020 if you use footage from the GH5 or EVA1. Or to slog if you use a Sony camera.
The Sumo sounds expensive to some of you? Mabe. But beaAware that you will Need a 1000nit unit for HDR editing anyway. The Sumo has also the disadvantage that it is HD only - but the advantage that you can use the internal waveform monitor with a better nit scale as available by now in Vegas (the new implemented 10bit waveform/rgb Parade has no nit scale yet, you need to know how the relationship between the levels and nits to grade for a specific nit level as required). A nit scale may come later. And another advantage of the Sumo is that you can set the Sumo HDMI output to HLG and use a Standard rec709 UHD monitor or even a HDR-TV as second Control monitor behind the Sumo. So this unit offers a lot of Advantages.
Another unit that could be used is the Dell UP2718Q, https://www.tomshardware.com/reviews/dell-up2718q-hdr-pro-monitor,5231.html . But it is not cheaper then the Sumo and allows only PQ but not HLG.
What I have seen is that it is most appropriate to use the ACES 1 with 1000nits in the project Settings for the ACES conversion. That will suit the most OLED-HDR-TVs, but be Aware that you have to grade to 600-800 nits today at the best (OLEDs does not achive a higher nit figure today).
At the Moment they have implemented PQ onyl. HLG may come later.
What they have implemented are metadata in the export function of the HEVC Encoder. That allows to create footage that should work on every HDR-TV, what is a big Advantage.

Beim Decklink Treiber gibt es einen Bug: nur dann, wenn man bei ACES 1 auch eine Transformation mit einstellt, wird bei meiner Decklink 4K 12G ein Bild hinaus übertragen.
