I second this.
I was seeing temps of approximately 85 degrees running MSFS. This week I started undervolting my Nvidia card (it will not damage it, no worries, there’s good stuff on youtube to check out if you want to try).
My card now runs on 750 volts, keeping the temperatures around 55 degrees and my frame rates went up by about 20 to 25% too, now the card has a lot more thermal space. Using MSI Afterburner, you just make an MSFS-dedicated profile that you can turn on and off so undervolting your card isn’t diffucult or permanent.
I followed exactly what this person was demonstrating and I’m very glad doing so.
