If you're like me, then watching the Fallout TV series on Amazon Prime reignited your interest in what is arguably the best Fallout game of them all — Fallout 4. Or perhaps, you never played the game and are interested in finally checking it out. Speaking of, Fallout 4 on Steam is currently ridiculously discounted at CDKeys, so you might want to snag it while it's so cheap.
Thing is, there are a few new ways to play this classic game now that PC gaming handhelds are common. So, I've taken some time to figure out what the best graphics settings are for Fallout 4 on Steam Deck as well as ROG Ally and Legion Go so you can get the most optimized playing sessions.

Best Fallout 4 settings for Steam Deck
Fallout 4 runs surprisingly well on Steam Deck with only a few small tweaks needed to get the best experience. Usually, I was easily able to keep the game within a 50 to 60 fps range, but sometimes it did dip down into the 40 fps range. You'll need to adjust game settings from the load menu before actually starting the game:
Open Fallout 4 → Options

STEAM DECK SETTINGS - TDP: 10W
- FSR: On (if plugged in or docked)
I found that mostly sticking to Medium graphics settings rather than the High or Ultra ones allowed Fallout 4 to run more smoothly on my Steam Deck. Additionally, turning off Godrays but upping Depth of Field to its best setting allows for good details. AMD Fidelity FX Super Resolution (FSR) is really helpful at making the graphics look better, but it pulls a lot of power, so I only suggest having it on if your Steam Deck is docked or otherwise plugged in while you play.
Once all of these settings have been put in place, you can back out of the Options menu and then click Play to start your game. Really, the game runs smoothly. The only semi-problematic part is when I manually have to pull up the on-screen keyboard to type in text, since the process feels clunky compared to a traditional PC. But, even that isn't horrible since you don't have to do that very much.
Note: Some games like Dragon's Dogma 2 don't run well on Steam Deck unless I put the system in Proton Experimental (learn more at our Dragon's Dogma 2 gaming handheld guide). This was something I had to change before playing Capcom's latest game, but I didn't have to do that with Fallout 4.
Fallout 4 on ROG Ally and Legion Go: Best settings
Considering that this game hasn't specifically been optimized for gaming handhelds and that it's a relatively old title now, it's impressive how well it runs on ROG Ally and Legion Go. But to ensure the best performance, you'll need to make some changes in the Options menu before fully launching the game.
Open Fallout 4 → Options
- Aspect Ratio: 16: 10 Widescreen
- Resolutions: 1280 x 800
- Antialiasing: TAA (Best quality)
- Anisoptiopic Filtering: 16 Samples

ROG ALLY & LEGION GO SETTINGS - TDP: 15W (can be higher if plugged in or docked)
- FSR: On (if plugged in or docked)
- FPS Limiter: Off
- VRAM: 8G (ROG Ally)
- Refresh Rate: 60Hz
I always recommend putting your ROG Ally VRAM at 8G, rather than the lower default. This allows the system to operate more smoothly overall. I got a decent amount of stuttering when playing Fallout 10 at 10 TDP, but going up to 15 TDP resolved this for the most part. Of course, 25W Turbo is even smoother, but it takes more power, so I only suggest doing it if you are playing the ROG Ally while it charges or is docked to a TV. Similarly, FSR drains battery, so you should turn it off unless the handheld is receiving a charge.
Frame rate wise, I was able to get as high as 90 fps in some instances, but overall the Legion Go and ROG Ally usually tended to swing anywhere between 50 fps and 80 fps. Whenever more NPCs or more in-game effects were activated the frame rate tended to dip.
Fallout 4 gaming handheld FAQ
Does Fallout 4 play well on Steam Deck?

Yes, Fallout 4 easily runs on ROG Ally and Legion Go. Of course, optimizing your graphics settings for the game will allow it to run even more smoothly.

With the Fallout TV series fresh in my mind, I've found myself drawn once more to Fallout 4. Of course, some of you might not have played it yet and so now is the perfect time to jump into this classic for the first time. If you haven't bought the game yet, then you should take advantage of the Fallout 4 sale at CDKeys and get the game at an extremely low cost.
Now that I've spent time playing the game on Steam Deck as well as ROG Ally and Legion Go, I can say that even though Fallout 4 is a few years old now, it runs really well on Steam Deck, Legion Go, and ROG Ally. Plus, the core gameplay really holds up, especially since it's bolstered by a compelling plot, fun combat, and plenty of dark humor.
