Gpd win 4 2025 input lag

So for the issue regarding the 3 frame input lag. Is there any possibility of a software update to fix this? Or is this going to mainly rely on them updating their hardware. I just received mine and noticed some input lag and couldn't tell if it was from frame generation or the system itself. Also I'm confused because alot of videos I watched online said that the win 4 is natively landscape. But when I powered mine on for the first time it was portrait in the windows setup. So is it even true that it's natively landscape? Thanks.
