Mobile environment performance dips when multitasking on high-end desktop builds

Hey fellow builders,

I’ve been tweaking my current setup (RTX 4080 / Ryzen 9) to act as a more efficient hub for cross-platform testing, but I’ve hit a weird bottleneck that doesn’t seem to be hardware-limited. I’m hoping someone here might have some insight into how Windows handles resource priority for mobile environments.

I spend a lot of time on mobile-desktop bridges, and while I was talking through some lag issues with the guys over at the arceus emaultor community, I noticed that my frame rates in-game are inconsistent despite my CPU and GPU usage staying well below 40%. It’s like the system isn’t “handing over” enough resources to the executor thread when other background apps like Discord or OBS are open.

Has anyone else noticed that mobile utility tools or scripts tend to trigger Windows’ “efficiency mode” even when the PC is set to High Performance? I’m also seeing some input delay that feels like a polling rate conflict.

I’m trying to figure out if there’s a BIOS setting or a specific virtualization flag I should be toggling to give these mobile environments better thread priority. If you’ve dealt with stabilizing mobile-to-PC workflows without the OS throttling your background tasks, I’d love to hear how you optimized your build for it!

Cheers!
