FPS Issue when exporting cockpit displays after SU05 update

Hi community!

since the SU05 Update the sim has become unusable for me. As soon as I export the cockpit screens for my homecockpit setup, my frames drop below 10 fps! This wasn’t the case before the update. Everything worked just fine. I tried reducing the graphics settings, no change. Using different glass cockpit planes, no change. Reinstalling the nvida drivers (clean), no change. Using older versions of the drivers, no change. Reinstalling the sim, no change. … I don’t know what else to do. Did anyone experience the same issue and knows how to fix it? If so I’d be really thankful for any help to solve the problem and get back to flying again…

My specs: Ryzen 7 3800xt CPU, RTX 2080ti graphics card, 32GB 3200 DDR4 RAM, M2 HDD for the sim. Main Viewscreen: 34+27" @ fullHD, Cockpit screens: 15,6" + 19" Screens
