Hello.
I have this problem that I'm running a game at 200+ fps and if I click in second monitor my frame will drops to 20, that 20fps is fixed and never changes.
The same thing happens on second monitor too, if I'm watching a video or youtube and even click on desktop of first monitor video will become a laggy mess.
Already tried everything I found on internet.
Disabled g-sync, disabled hardware accelerator for discord and made sure my monitors refresh rate are multiple of each other.
My specs:
R5 3600x.
32gb ddr4 3200mhz cl 16.
RTX 2060
x570 motherboard
Monitors:
Lg 27gn750 240hz
Lg 24mk430 75hz (runs at 60hz right now)
Windows performance mode is set to AMD ryzen high performance.
In ryzen master precision boost is enabled.
