    Is it normal that in HDRP sample scene my GPU temperature constantly rises over 90 C in 30-40 seconds?
    At 100 C, my GPU will be physically damaged so it's impossible for me to utilize HDRP for my game.
    I have a notebook with GTX 1060.

    If I load similar assets into a standard pipeline scene, the temperature doesn't go over 60C.

    If there's something in the HDRP scene that's causing the GPU to overheat, I would like to know what is it and if I can get around it.

    Get a laptop cooling pad. This is a hardware issue :).

    Hey Hexer_

    Is this a regression was the overheating as bad in another Unity version? If so could you file a bug please with the Unity and HDRP version please and post the bug number.

    Something to note is that HDRP will tax your system generally even with the sample scene.

    Hi @JohnC_Unity !
    I tried running the same HDRP sample scene in 2019.1.11f1 and the GPU temperature doesn't go over 70 C.
    No problem, I'll file a bug report with as much details so you can investigate it further!

    But just in case, I'm getting that cooling pad as @Tautvydas-Zilys suggested! :)

    Hi @JohnC_Unity !
    I can't update the original bug report so I'm posting here..

    I did some additional research and I can confirm that in Unity 2019.2.0f1 with HDRP 6.9.1 there's no overheating, the GPU's temperature stays between between 65-70C.

    So, overheating just happens in Unity 2019.3 regardless of the HDRP version I install.

    Hi, I just received reply from support that they managed to reproduce the issue in versions 2019.3.0a10 and 2019.3.0a11. However, they couldn't reproduce it in 2019.3.0a12 so it seems it's already been fixed :)
