syncing issue with proton or steamdeck

Product: Need for Speed: Unbound
Platform:PC
Summarize your bug there seem to be syncing issues where gameplay is run so slow or unplayable while the framerate is always passed to 30 or 50 fps
How often does the bug occur? Every time (100%)
Steps: How can we find the bug ourselves? 1. get a Steam deck an SSD one like the 512GB or the 256GB 2. run nfs unbound via the Steamdeck proton feature note run this on full wireless connectivity with no wired 3. go to Lakeshore online 4. get on a full session and go to maps and select anywhere on the make 5. drive on free-roam you will notice tons of lag and the car seems to run so much slower despite playable framerates
What happens when the bug occurs? the car and the game seem to be slow sometimes stutters when running with a bunch of cars while the game is slow the hud and the timer run just fine it's just the inner gameplay that is unplayable
What do you expect to see? I would recommend getting in contact with valve developers or working with Valve to see if its a valve issue or an ea issue on server stability and maybe in the future to get nfs unbound steam deck verified or that fix the syncing problem in volume 4

please note its not a connection issue on my end I have 1 gig fiber internet and I was close to the router when this was occurring all drivers are up to date with Valve and I did also report this to Valve as well knowing about the syncing issue as well here a link https://steamcommunity.com/app/1675200/discussions/1/3812911294781469747/
