How is your performance? Are you in desktop outputting to 1080p or are you just in game mode outputting 800p to the TV? I have death stranding on PS5 but I've shelved it to get back to my PC collection and I'm looking to purchase death stranding ce during the summer sale.
I'm not streaming from Desktop. Steam Deck supports resolution up to 4K when docked so you won't be playing at 800p too. Not sure if you already know the following but there seems to be a lot of confusion surrounding this topic so I'll share my experience here in the hope that it'd help clear things up for someone. Below is the tinkering process that works for me:
Go to Steam - Settings - Display - External Display. If you have a 4K TV and want the game to run in 4K, leave Automatically Set Resolution on (because there's no option to pick 4K in custom resolution for reasons unknown to me). If you want a lower resolution, turn off Automatically Set Resolution and pick the res you want.
Go to Library, click on the game then go to Settings - Properties - Game Resolution and set it to Native.
Start the game, set res in the game to the a res lower than what you set in system display. For example if you have a 4K TV and set res to auto in system display, you'd want to set it as 2560x1440 in game. If you set 1920x1080 in system display, set it to 720 in game. Next step will explain why.
Open your quick access menu (the physical 3 dots button under the right controller pad), scroll down to battery icon and go to Scaling Filter and slide it to FSR if it's not already in this mode. What this does is that it will scale your in game res to match your system res with very little impact on your game performance.
You'll get about 20fps at 4K, and around 30fps at QHD(2560x1440). Personally I left it at QHD and it has mostly been running very smoothly except for the occasional crashes... Just make sure you save your game regularly.
Thank you for the reply. I'll have to give the fsr setting a try sometime. I usually am either away from home and play in game mode native or I'm at my desk with a hub in desktop mode outputting to native 1080p which incurs a performance hit.
