Linux windows VAST performance diff

[AyaanMAG]

I have an Acer predator helios 300 2021 with an rtx 3060 and an i7 10th gen. On linux i don't need to apply any undervolt and my cpu runs at a comfortable 40°C however the moment i use windows i need an undervolt to keeping it from idling around 90°C and the least I've gotten it to is 70°C.  When I'm using multimc to open Minecraft from the same exact installation on both, using my RTX 3060 GPU I'm getting barely 70fps while my i7 10th gen on linux alone can fetch 135. I haven't been able to get nvidia GPU running on linux yet as in my distro has the drivers installed but it doesn't show up in the "nvidia X server settings" so i can't force Minecraft to use it and currently it's not. But that's an issue for a separate time

 

Why the vast performance discrepancy, why is windows more hellish for performance can i get some help fixing this?

The two things I can think of are either your monitoring system in Windows reads Fahrenheit for whatever reason (IIRC one of the Corsair software suites does this by default) or you've got a virus mining some sort of cryptocurrency on your CPU. Given that you're getting significantly better gaming performance on Linux, I'd lean towards the virus of some sort, but that could just be that Linux's Intel drivers are a lot better than the Windows drivers (both aren't great though). 

 

Run an antivirus of some sort (Malwarebytes is generally pretty good for this) or just do a clean install and see if that fixes it.

Probably as simple as switching on close source drivers and the distro check for them.

 

As for the temp issues, something is wrong with your software setup by the sounds of it, because it shouldn't do that

Disable startup items that are not essential, sounds like a background process is abusing your CPU time.

 

I see pretty similar performance between Windows and Linux on my 8th gen i5 laptop, similar temps as well. Generally Linux idles cooler just because there's less background processes but once Windows settles down they're not that far apart.

I'll run an antivirus but I'm generally good with computers and shouldn't have any viruses, it also shows the appropriate amount of cpu usage as per the amount of use so i suppose the virus could be fudging those numbers somehow?

 

Also I've used multiple monitoring software and both are in °C. I can feel the difference when windows makes touching my laptop keyboard hot to the touch vs linux where it's room temp

What are the fans doing?  Is something in Windows forcing a silly fan curve?  Is there an obvious increase in heat output in Windows?

Oh i have a laptop, it uses proprietary software to control the fan, the temp i talk about are on the lowest fan speed on both

Yes but the thing is i have most of the same stuff on linux, jellyfin, syncthing, flameshot, veracrypt, most of what would be on windows anyways
