Multi Client 2 monitor issue FFXIV

[FlashGuard]

Hello everyone here are my specs.

CPU: Ryzen 7 1700 8 core 16 thread Stock 3.0Ghz
MOBO: ASRock x370 PRO4 AM4
RAM: 2x 8GB TForce Vulcan 288pin DDR4 2400 PC419200
VID: ASROCK Radeon RX 580 8GB OC

Here is my issue. Final Fantasy XIV has the ability to run multiple clients with no issues given that your PC has the resources for it. Which in this case mine does.

There is an option where you can limit the FPS when the window is not selected. i want to clarify that i have UNSELECTED this option. Both clients are Borderless.

So while running 2 clients the game runs well. Except for one issue. Which ever window the mouse is on is considered the MAIN by the system. When this happens the selected window runs as expected. However the other takes a nose dive to 25 - 15 FPS. Running the game normally i can get 120 FPS. Both Clients are limited to 60 FPS. i have tried many things such as running on DX9 instead of DX11. Changed video settings as far down as possible. Even lowering resolution. The game is playable on the other monitor. However it as if windows is setting a priority for just that window. I have also changed the clients CPU core usage and set the priority to High. My PC has plenty of room left for the other client to get good FPS. It does not make sense.

What is your cpu/gpu usage when you play only one instance?

What is your cpu/gpu usage when you play only one instance?

CPU is around 25% to 40% As far as the GPU memory usage is 1.5GB and 3D usage is 95% which makes the GPU show 95% But i can easily run both. I have tested this with other games like Portal Knights and never had any lag.

Ok i opened both to give more info. CPU is 36% and GPU is 99% GPU memory is 1.9GB 99% to 100% usage.

Once i closed a client CPU Dropped to 9% GPU 76% While using 1.3GB VRAM drops to 1.1GB used if i drop all settings to Minimum. FPS spikes to about 150 when i do.

As a side note ARK uses 15% CPU, 9GB Ram and 99% GPU Using 4.5gb VRAM. Ark gets around 45 - 50 FPS on high detail and around 65 - 70 FPS if i lower the Video settings to nothing.
