Hi.
specs:
Render gpu: 4090 at x16
Ls GPU: 6500 xt at x4
Mobo: Asus z790
games tested: cyberpunk and hogwarts legacy.
I set the 4090 as performance card in windows, LS set to 6500 xt, restored both graphics drivers but nothing works.
Problem: i have good fps without activating LS, but when i set on the fps goes to 30 or worst. something weird it's that the gpu usage for both GPUs are 99% even without using LS.
thanks for helping.

What's your display resolution and refresh rate? Are you capping base fps? 100% usage before scaling means it uses whole bandwidth already

im using a 4k oled tv at 120hz. im not caping the fps. the usage of both gpus before activating LS is high but not 100%
The Oled tv is conected to the 6500 xt and the other two monitor to the 4090. already tried using just the tv and desconecting the monitors but it happens the same.

Well, 6500 isn't enough for 4k HDR without any fps caps. Cap base fps at 60

I'm testing with my 2k monitor same thing happens. But, if cap the fps to 60 like you said or even 120fps in game the 6500xt utilization goes to 50-60%. So I have to cap my whole fps with something like rivatunner?
