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! 
@JohnC_Unity my bug number is 1173478
Awesome. Thanks for taking the time to post a bug Hexer_. This will help us out.
Cheers
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
OK great stuff!
Hopefully youre laptop won’t melt with a12. Thanks for taking the time to post a bug report!
Should not, apparently he bought a stand))
I have tested new empty scene with one cube and light.
GPU overheats when entering Play mode.
HDRP 7.1
Hey guys, have they made any updates this? Is 2019.4 better?
Edit: I’m using a 15inch MBP and 2019.3 made the system halt a couple of times, as well as overheat a bunch
My scenes were jumping my 1660 up to ~90C until I realized it was running at 1000+ fps, so I limited it to 144 and now my temps are stable at ~60C.
To do this, just make an empty game object and add a C# script that has a Start() like this:
void Start()
{
Application.targetFrameRate = 144;
}
I’m not an expert, but I don’t think this is a permanent solution, just a band-aid for an optimization issue.
Don’t use Application.targetFrameRate. It’s horrible if you want your game to look smooth at all. Enable VSync instead.
Listen to Tautvydas-Zilys.
To enable vsync, put this in your game:
void Start()
{
QualitySettings.vSyncCount = 1;
}
The “1” there represents the refresh rate of your monitor.
Hey Folks, it should be up on the asset store now.
Does this overheating problem is still there in Unity 2020 latest version released in November.??Does this overheating occers while using other features also??I am worried as it may cause harm to my Laptops GPU.
