I am running an Alienware Aurora 12 - Intel Core i9 @ 3.50GHz and 4095MB NVIDIA GeForce RTX 3090.
It's a brand new computer (Gotten it in October 2021) which also stands in a rather cooling draft of air as I keep my terrace door open all the time in my computer room.
I also clean out my computer every month with a brush, can of air and a vacuum cleaner ;-)

When playing Valheim, no matter if solo or with friends, my CPU goes up to 70+ Celsius and my GPU around 67 Celsius. And I tried all the hints, Tips & tricks found on reddit and other pages found with aunty google. Nothing worked. It's either CPU & GPU getting too hot for my taste or the CPU is getting too hot for my taste.

I play various other Games (Rust, BG3, ESO, Battlefield, Divinity 2, Witcher 3, Borderlands 3 yaddayadda) on high / max settings without my CPU or GPU breaking into sweat.
CPU and GPU usually stay nicely below 60 Celsius.

The CPU usually picks its nose with 35 - 45 Celsius unless I do my 3D artsy stuff in ZBrush & Carrara 8.5 Pro on maxed out high quality settings & high poly & ray count. But even then my CPU doesn't go even near 60 C.

Many player have the same issue - Valheim overheats their CPU or GPU (or both), while other Games & applications don't.

So my question now is - will this issue be fixed/optimized in Valheim or do we have to expect it to stay like this as a final result?
