[Performance Fix] For Windows On Steam Deck

[Yanderexoxx]

This guide will help you speed up your performance when using Windows 10 Or Windows 11. I’m only posting this because I couldn’t find a tutorial anywhere talking about this.

So for some reason after you install Windows on your steam deck windows only recognizes 1 or sometimes 2gb of vram (Video Ram). It cycles between them. To fix this is very simple. It took 4 weeks for me to figure this out due to not finding any tutorials on how to fix this problem. I just figured it out on my own.

Windows Tweaking Performance:

1, Disable or Uninstall Xbox Game Bar

2, Turn Off Notifications (Automatically off if you choose gaming mode on setup)

Bios Fix For Windows

1, Power off device

2, Press and hold the power button and the volume up button. Until the recovery screen appears.

3, Select utility setup

4, Navigate to the advanced option

5, Open the drop down menu of UMA Frame Buffer Size

6, Change to 4g

7, Save And Exit

*Optional

While In advanced settings change power control to max. This will increase performance *when plugged in.*

Remember:

Windows isn’t technically designed for the steam deck. It’s more experimental than anything else. Drivers will malfunction and the Os might be buggy. Also you might run into a watermark message saying your pc doesn’t meet requirements for windows 11 / 10. But luckily there’s a bypass for it.

Is there any benchmark showcasing increased performance from disabling notifications?

Use steamos for best performance...

Thanks for sharing.

You have to use windows for certain games (Call of Duty for example) and overall it's much easier as you can play your games directly without some launcher or proton nonsense.

There's not a single game that lags in windows but runs smooth under steamos.

Yes you can use superposition benchmark. But I did forget to mention after switching the uma settings windows will begin to freak out for a little bit. I guess it’s trying to figure out what you did. After two clean restarts it starts functioning like normal.

Not in all cases, steamos is Linux. Initially it is faster but some games don’t run on Linux. You have to have windows for. As long as you heavily modify windows for gaming it runs the same. Deleting unnecessary applications such as Microsoft teams, and Xbox game bar it runs smoothly. I even had it running Vr for a bit and surprisingly it worked fine except for oculus saying pc doesn’t meet requirements.
