Steam Deck38 Reports
Disabled motion blur via config files.
Locked refresh rate to 45 Hz and in-game fps to 60
Input functions strangely. If the in-game FPS is set to 60 and you lock the refresh rate to 30 or 40fps, there will be noticeable input delay or lag. This is most noticeable while turning the camera as it'll move and stop with noticeable lag. This is even more pronouced if the fps is capped at 120 and you play at 60 or 30. 45 is a good sweet spot where lag is less noticeable and saves on battery.
I am playing with my SD docked on a 1440p@120 screen. I suggest a 75% render scale with all the details at low and limit the FPS to 40 when VRR is not supported (or 30 if your screen is @60). The strong graphic point of the game is the HUD, which looks wonderful at high resolutions.

Enabled screen space reflections per PCGamingWiki
Game ignores resolution set by Steam Deck and tries to fill the whole screen, despite being made for 16:9. This can cause weird artifacts to appear in the top and bottom rows of pixels. This can be mitigated with either running the game in a window and setting the resolution from there, or using P3Rfix below.
Graphics settings are saved into the individual save slots, meaning you'll likely have to manually change your graphics settings if you go between Steam Deck and PC.
Additionally, Episode Aigis DLC will not respect your settings from the main game, and you'll have to set them again. These are not Linux or Steam Deck problems, but problems with the game.
I am using a DeckHD screen and custom cooling solution (PTM thermal pad). Below are the options I'm using, which has given me 60fps in most areas of the main game and extremely consistently in the Episode Aigis DLC.
On my Steam Deck, I have Unified Frame Limit Management settings disabled in the system settings (bottom of Display tab), so I can set Refresh Rate and Framerate separately.
Steam Deck QAM (... button):
- Framerate Limit OFF
- Refresh Rate 60 Hz
- FMVs run at 24 or 30fps, and as such, odd refresh rates should be avoided
- Allow Tearing ON
- YMMV, but I haven't noticed any tearing.
- Remember: only ONE tearing prevention option should be enabled at a time, if any are enabled at all
Ingame settings:
Graphics Settings:
- Rendering Scale 75%
- only if playing at 1080p; 100% should be good for 720p
- Shadow Quality Low
- or Middle, can again depend on resolution
- Frame Rate Limit 60
- Reflections OFF
- This setting specifically controls Ray Traced Reflections and WILL turn the game into a PowerPoint presentation if left on
- Using PCGamingWiki fix, this should still allow Screen Space Reflections
Display Settings:
- Screen Mode: Fullscreen
- Window if you don't want to use P3RFix
- VSync OFF
- YMMV, but I haven't noticed any tearing.
- Remember: only ONE tearing prevention option should be enabled at a time, if any are enabled at all
I also installed P3Rfix and changed the individual lines of the P3RFix.ini file as follows (do not just copy this):
[Custom Resolution]
Enabled = true
Width = 1920
Height = 1080
[Intro Skip]
SkipTo = 1
[Enable Console]
Enabled = false
Persona 3 Reload runs fine on the OLED Steam Deck while maintaining a 45FPS lock in 99% of playtime.
FPS limited at 45FPS@90Hz via Steam Overlay
In terms of dungeons, Harabah floors are the hardest to run. Most of the area is fine but there is one spot in particular where it always significantly drops below the 45FPS cap. This is easily tested on floor 225 where you can teleport to. Try running around upwards and turning the camera backwards. The FPS will slow down noticeably from 45 to the mid-30s. Any FPS cap, even 30 will drop frames (in this case, dropping you to 28/29).
Outside of the area mentioned in my report, you'd be hard pressed to find any other moment in the game where the 45 FPS lock isn't appreciated on the OLED Steam Deck. It balances battery life with performance, all the while at 100% resolution scale, High Shadows, Reflections Off, 120 FPS in-game (serves as our 'unlocked' framerate since we will be locking to 45) and V-Sync turned off.
Désactiver les reflets - ce sont des effets unreal 5 très consommateurs.
Désactiver les reflets - 125% de netteté - tdp 7W
Tourne très bien tant que les effets lumen (reflets) sont désactivés.
Rendering Scale: 100% Shadow Quality: Middle Reflections: Off
This will give you 60-90fps.
Stable 60FPS outside of rare occasions opening menu and character switching on some dungeon areas. No issues with graphics, even in dense crowd areas. Turn off reflections as this is ray traced and will tank performance, otherwise graphics can be set to high.
Set screen refresh rate to 50hz on battery power
The game runs perfectly fine on the default version of Proton - no noticeable performance difference when running it on Proton Experimental.
I did experience a lot of constant framerate drops/stuttering when I had reflections enabled. Would be borderline unplayable in areas other than the Velvet Room and the dorm.
Some frame drops here and there but runs exceptionally well otherwise.
Settings: Rendering Scale 100%, Shadow Quality Low, Frame Rate Limit 60, Reflections Off
The game works extremely well with Proton Hotfix version. Stable 60 fps without freezes or crashes.
Even on Proton hotfix + no reflections + lowest preset it is unplayable as the game has no autosave
Hard Crashing in Tartarus dungeon (often) and during normal activities (a few times)
After changing the Proton version to Proton Hotfix, the game is able to run at a stable 60 fps, and gets about 2 hours of battery life.
Proton experimental bleeding edge and 40hz refresh rate
Rarely had audio start crackling after putting the system to sleep and waking it back up
Make sure reflections are turned off as they are raytraced when on. Without proton experimental being set to bleeding edge game was playable at 40hz with 75% render scale. However when using bleeding edge 50-60 fps could be achieved with 100% render scale, which I would then cap for a near perfect 40hz expereince.
SteamOS: 50 FPS In-game: Default settings, but reflections set to OFF
Reflections must be set to OFF. - Some areas like Paulownia Mall would suffer significant slowdowns if the default ON setting is kept. Setting it to OFF fixes the issues entirely and you'd get mostly high frame rates for the entire game.
I was able to play P3R all the way to August (at the time of writing, still playing the game clocked at 23.9 hrs) mostly on the deck, and also while docked as long as the provided settings are applied, and while putting the Steam Deck on sleep and resume.
There were no crashes, in-game issues or glitches encountered since purchase.

Turn Raytracing Reflections off -FPS runs at high 50s nearly everywhere including the first 2 blocks of Tartarus, high 40s in the Velvet Room on high settings -FPS runs at a nearly locked 60 on 75% scale including the first 2 blocks of Tartarus, high 50s in the Velvet Room.
Set the TDP to 9W
Game runs okay on the SD, with Reflections turned off (This disables RT reflections) and everything else set to high. Gives locked 45 fps (on Oled deck) in most locations, but dips to 25~30 fps sometimes and is noticeable. Reducing shadows from high doesn't improve the framerate, only way to get better framerates is to reduce rendering quality to 75% which doesn't really look good.
It ran properly for a bit on the Deck's Preview channel but then it broke again. Not worth it on the Deck.
Game was kind of all over the place before when using the default Proton version, frequently stuttering and struggling to hold 30 fps in some areas.
Switching to the latest version of Proton Hotfix solved all of the problems with this excellent game on Steam Deck! Plays like a dream now!
Game's main dungeon is basically unplayable as i can't go 5 floors without crashing. different, seemingly random, causes every time

Forced disabled RT effects as well as motion blur in configuration. Also have Mesa 24 downloaded and forced in launch options.
Reflections disabled, medium shadows, 100% resolution scale on OLED Steam Deck. With Proton Hotfix and Mesa 24 I'm holding a locked 60 fps with a minor dip initially loading the Velvet Room, after which it stabilizes at minimum 58 there. Getting approximately 3-4 hours battery life.
Change proton to hotfix and all the slowdown is gone! Also recommended to change steamos to preview for maximum performance! Turn off reflections ingame.
You can change the resolution through properties outside the game and then use the ingame resolution of 1440x900 for much sharper graphics. Amazing game to play on the steamdeck!!!
Turned the TDP down to 8
The FPS Drops have been fixed, the game now runs at a locked 60fps if you run it with Proton Experimental Bleeding-Edge. With this fix my older report is now outdated.
I think with the constant fps drops and stutters a typical user would not have a good time with this game in its current state
limited tdp to 9 watts
constant slowdowns stutters and fps drops
Given the game runs absolutely flawlessly on a Steam Deck with Windows WITH RAYTRACING ON MIND YOU, I really think Proton needs a patch for this game. It's a shame too, this game would be a perfect Deck game, all of the other Persona games run fine too. I really hope a Proton patch comes soon...
Numerous stutters would occur due to broken shaders as reported in this source. Before, certain areas in tartarus, the dorm room, and also the velvet room would stutter and dip up to 20fps.
By applying the latest proton hotfix, the aforementioned stutters are now barely noticable, and I get consistent 60fps in most areas. For tartarus, there are still occassional dips but I can confirm that it's mostly 60fps. My dorm room no longer has a low framerate and it is locked 60fps. For the velvet room, whenever the background light appears it'll at most cause the game get 48fps, but most of the it is 60fps now. And this is tested on my end with Resolution Scale 100%, Shadows High, and Reflections off.
Use the latest Proton Hotfix.
As mentioned by other reports, numerous areas such as the velvet room, the dorm room, and also certain areas within Tartarus stutters with framerate dipping into 20fps even with reflection turned off. However, for some reason, the steam deck on windows performed way better compared to steamOS, which dictates that something is not right with Proton itself.
According to this Source, it appears that the problem is a result of broken shaders caused by Proton. As such, the only feasible tinkering method to resolve the stuttering issues is through using Proton Experimental - Bleeding Edge. Once you have switched to this version of proton, Tartarus gameplay is much smoother with consistent 60FPS at Resolution Scale 100%, Shadow Medium, and Reflections turned off. Velvet Room still stutters when the light appears in the background, but it is much smoother with 40FPS dips rather than the usual 20FPS dips.
Opt into SteamOS 3.5.14 Preview for improved performance of ray-traced reflections (Settings > System > System Update Channel).
Limit TDP to 7 watts.
Based on Digital Foundry's tech review, it seems that Persona 3 Reload uses a form of ray-traced reflections. Unfortunately, these ray-traced reflections significantly impact performance, especially in Tartarus. The "Reflections" setting in the "Config" menu is misleading, as disabling doesn't remove reflections outright. It removes ray-traced reflections in favor of a screen space fallback. Although Value has released a preview update for SteamOS meant to address ray-traced performance, I'd recommend disabling it to favor higher, stable framerates. This game also has performance issues with lighting, with noticeable dips in areas with dynamic light sources, such as the hanging blue lights in Tartarus and the elevator lighting in the Velvet Room, making it hard to target a stable 60 or even 40 fps in these areas even on low settings.
Due to the performance issues related to dynamic lighting and ray-traced reflections, I'd recommend targeting 30 fps on low graphics quality with "Rendering Scale" lowered to 75% and "Frame Rate Limit" increased to 60 or 120 fps. Instead, limit the frame rate to 30 fps in the Steam Deak's performance tab. I recommend limiting the frame rate through the OS instead of in-game, as it leads to a more consistent frame time and a smoother micro stutter-free experience. I also recommend limiting the TDP to 7 watts for improved battery life. You could go as low as 6 watts, but I found 7 watts to have a more consistent frame time. These tweaks should yield an enjoyable, stable 30 fps experience everywhere except the Velvet Room, where you can experience dips to the low 20s.
TDP Limit 6 watts
Certain light sources tank the FPS to 20 or lower. Graphics settings and TDP make little to no difference. An example would be the Velvet Room.
Change render resolution to 75%, shadows on high, and RTX reflections off. You'll get locked 30 fps at as low as 6 watt TDP (exceptions being the specific problem areas). These settings can get you 2:30-3 hours of battery. Lowering the actual game resolution itself (NOT the render resolution) can improve the areas with problematic lighting, but they'll still be sub 30 fps.
(All of this is with the Reflections disabled) Very noticeable FPS drops while exploring Tartarus - might have something to do with how the game handles light sources, as getting near a teleporter or window with light shining through it causes the fps to drop significantly, from 50/60 to the low 20s. Significant performance problems are also noticeable in the Velvet Room, whenever the elevator with a shining white light drops down, the game slows down to a crawl for a few seconds.
I'm certain that most of the other reports here are from users that have only played through the first few hours and didn't get to explore Tartarus yet. With how this game plays now, I would not recommend to buy it on the deck.
Lowering shadow settings does not fix this issue.
Laggy in certain areas for no apparent reason. Average framerates tend to vary wildly from 20s up to 90 although frametimes are very consistent and there is no stuttering. This is notable while exploring tartarus or simply being in the protagonist's room. Reducing the graphics settings only alleviates this slightly. It is also necessary to disable reflections to get playable framerates in some areas, they are on by default.
to play this at 30fps docked, i had to reduce the resolution so the game world was really blury, NIS kinda solved it, but it was playable.
some small slowdowns in menus but nothing too major
this game requires too much tinkering to be deck verified, but after you do said tinkering, its a fun way to reexperience persona 3
TDP set to 11 and Medium Settings locked to 30FPS will bring 6hrs from full charge on Steam Deck OLED.
Laggy when playing with "High" video Quality.
It is playable, but it will be laggy if using default video setting to play it - Should change to "Low" to fix this problem. Change to Proton GE could not solve this problem.
Works decent out of the box. However, it'd be better if you change the graphic settings to look like this:
Graphics: 100% Shadows: Low Reflections: Off Performance: stable 60 fps in combats and menus, and 38-60fps while traversing zones. I haven't noticed stuttering when the fps jumped to 40 or so, but you can limit the fps to 40 if you want to. Either case, works super well with these settings. The one that has more impact in the game seems to be the reflections. The game ran at 12-30fps for me with reflections on, so keep that in mind.
Frame rate can drop in certain areas
Be sure to turn off Reflections in the Graphics Settings as areas with mirrors or other reflective surfaces can heavily degrade performance.
Otherwise, the game can have some slight performance drops in areas such as Tartarus and the Velvet Room.
Turn graphics to low, rendering scale to 75%, reflections to off, and max frame rate for 60 for locked 60 fps on most fields and ~2 hour battery life.
Set graphics to medium, limited fps to 30 -> 6h battery life on Deck OLED
