MacOS: M3 Excessive Fan

When I play WarThunder on my M3 iMac, the fans kick in very early in a match and roars throughout the game. If I switch to another app, putting WT in the background, the fans soon stop.

The M3 chip has multiple cores and “dynamic caching” in its GPUs increasing GPU processing with hardware acceleration, ray tracing, yada yada yada. The GPU is supposed to be 2.5x faster than the M1 family.

So why the fans?

I feel as if I’m missing a setting in the WT Launcher and am forcing “old school” rendering rather than harnessing the power of this updated chip.

I guess I’m looking for confirmation from other M3 Mac pilots. Are your fans kicking in during your missions? Or do you get insane graphics and frame rates by being smarter than me?
