this is the website, basically the homepage lags on computer and i have no clue why. (it doesn't lag at all both on Dev and mobile)
I've tried compressing the main video down to 1 mb, using the Video from next, multiple formats(mp4, mov, webm etc) ,using it both from R2 and local as well as some other tweaks:

<video 
                className="absolute inset-0 w-full h-full object-cover" 
                style={{ willChange: 'transform' }}
                src="https://pub-768f808dc5fe4b5284d814f5967be01c.r2.dev/psaIntroFinal.mp4" 
                // poster="/learnPortraitUpscaled.jpeg"
                preload="none"
                autoPlay 
                muted 
                loop 
                playsInline 
            />

Im really desperate because the only way to avoid the lag seems to be removing the video but i really don't want to do that.(the video is down at the moment)
