FPS drop using with 2 4K monitors, Dell D6000 and MBA M1
 

I have some FPS drops while I'm using 2 4K LG27UL-500 monitors. Both monitors are connected to Dell D6000 DisplayLink Docking Station and the dock is connected to MBA M1 16/256. My mac is running MacOS Monterey 12.1 and DisplayLink Manager 1.6.0 (Build 59.128). I have thoroughly checked all the preferences and settings and everything "seems" to be fine, yet I do notice some lags while changing windows on a single monitor. Mac shows 60 HZ, yet it seems to be reduced a bit? In addition, DL Manager does not boot up during login page even though I have downloaded the Login additions. Any help is much appreciated
