Unity HDRP project lags in fullscreen

Hello,

I need help with Unity's HDRP Render Pipe line. I want to make my next game with HDRP and it works perfectly fine in the minimized window. But the moment I make it fullscreen, it lags and has only 16 fps. I already tried some settings like the Render scale or the screen resolution. Nothing helps me. I only found one more guy on Unity Discussion with the same problem. He upgraded to Unity 6. I did that too and still have this stupid problem. My scene is empty, it has only a basic character controller.

Can someone help me pls? ):

I'm no big-brain with resolution and stuff, but I might be able to help. DM me on discord (prefered) my user is sniper61385 or email me realsniperapps@gmail.com and I'll try my best to help. I know a lot about unity and libraries, so I might be able to help you fix it.

There's a lot more that goes into HDRP than can be seen in one screenshot. I would need to see the volume profile and GPU usage in task manager just to get a basic understanding of your scene.

I have a screen shot of the profiler here (the first 3/4 frames are when I play with the minimized window and than comes the fullscreen):

I'am working an my Macbook (M1 Air) so I can only show this little window from Stats. It shows some really high values. Even when I minimize 

the window. So my PC is burning inside but its smooth when I playing my game on a little window.

I would say your problem is that you're using an apple product but that doesn't really solve anything. Unity usually only uses 30 to 50 percent of the GPU, at least on my personal computer, with HDRP. So low framerate would be expected, but if your PC really is at 100 percent utilization it probably is actually because of the device itself. Apple products don't really have good hardware, built-in graphics on anything is usually pretty terrible. Though still not knowing what your volume profile has on it I have no idea if it is because you're on an apple product or if you have some feature on that eats up performance. Like ray-tracing or volumetrics.

If I turn off the fog & sky volume my fps are around 30. But in the minimized window I have 100fps.

I just use the basic volume (it's a new scene).

Physically based sky uses a lot of performance, but also if minimizing the window decreases the resolution then the performance is going to get a lot better. Looking at your stats window it looks like you probably have free aspect on, so a smaller window is going to be a lower resolution than when it's maximized, so of course the fps with be low. What resolution is the screen on your device?

My screen resolution is 2560 x 1600. I cant find the correct settings to solve the problem. I tried setting the max. resolution to 1280 x 720 (in the Unity settings) but it shows no changes.

It's right here.

Holy sh*t. Just saw you activated low resolution aspect ratios. I dont really know what it does but it boost my game to 80 fps in fullscreen and 150fps in the minimized window. Thanks!

I always tried changes in the player settings but this never changed anything
