If Citizen Sleeper 2: Starward Vector is crashing, freezing during a transition, or dropping below a smooth frame rate, the fastest fix is a clean PC baseline: verify the Steam installation, update your GPU driver, disable overlays, reset the game’s graphics configuration, and cap FPS to a stable target. Most players should begin at 1080p with V-Sync enabled, fullscreen or borderless mode tested separately, and background capture software closed.
The game’s presentation looks deliberately illustrated, but that doesn’t make every performance problem cosmetic. Citizen Sleeper 2 runs through a PC rendering pipeline that can still react badly to corrupted files, driver hooks, Windows scaling, shader compilation, and overlays. The fixes below are ordered from low-risk checks to deeper repairs, so you won’t need to delete a save or start over just to troubleshoot a bad launch.
Start with the fixes that solve most crashes
Before changing advanced settings, establish whether the problem is the game, Steam, or a third-party program. Close Citizen Sleeper 2 completely, then quit Steam from the system tray rather than simply closing its window. Relaunch Steam as administrator only if normal launching fails; running every game as administrator can create permission mismatches with save folders, so don’t make that the permanent solution.
1. Verify the installation
In Steam, right-click Citizen Sleeper 2: Starward Vector, choose Properties, open Installed Files, and select Verify integrity of game files. Let the process finish even if it appears stuck near the end. A missing or altered executable, asset bundle, or shader file can cause a crash at startup or when the game changes location.
2. Update the game and GPU driver
Install any pending game update first, then use the official NVIDIA App, AMD Software: Adrenalin Edition, or Intel Graphics Software to install a current driver. If crashes began immediately after a driver update, use the driver’s clean-install option or roll back one version. Avoid random “driver booster” utilities; they frequently add another troubleshooting variable instead of fixing one.
3. Turn off hooks and overlays
Disable the Steam Overlay under Steam’s game properties, then test with Discord Overlay, Xbox Game Bar, NVIDIA ShadowPlay, AMD Instant Replay, MSI Afterburner, and RivaTuner closed. These tools inject themselves into the rendering path. They’re useful for monitoring, but a simple narrative game has little to gain from running several capture layers at once.
For more context on diagnosing hitching, compare this workflow with Steamoz’s Ironborn stutter and FPS settings guide. The principle is the same: change one variable, reproduce the problem, and measure the result.

Citizen Sleeper 2 is not a competitive shooter, so chasing 144 frames per second is usually less valuable than eliminating frame-time spikes. A locked 60 FPS feels cleaner than a fluctuating 45–100 FPS presentation, especially when the game moves between dialogue panels, station maps, and animated scenes.
| Setting or action | Recommended value | FPS impact | Visual or stability note |
|---|---|---|---|
| Resolution | Native 1080p or your display’s native resolution | Medium | Lower to 1600×900 only when GPU usage is consistently high |
| Display mode | Fullscreen first, then borderless if needed | Low to medium | Borderless can improve alt-tabbing but may add desktop compositor overhead |
| V-Sync | On for a 60 Hz screen | Low | Removes tearing and steadies presentation; test off if input feels delayed |
| Frame-rate limit | 60 FPS, or 30 FPS on weaker hardware | Improves consistency | A cap reduces heat, power spikes, and uneven frame pacing |
| Anti-aliasing | High or default | Low to medium | Lower this before resolution if the option is available |
| Effects, shadows, and post-processing | Medium | Medium | Reduce these together when animated scenes trigger drops |
| Upscaling | Off at 1080p unless available and needed | Potentially large gain | Use Quality mode at 1440p; avoid aggressive Performance mode blur |
Apply the profile, restart the game, and test the same scene for at least five minutes. Don’t judge performance from a single menu opening: the first visit to a location can include shader compilation or asset loading. If the second visit is smooth, the original hitch was probably a one-time cache event rather than a sustained hardware limit.
If you’re on a laptop, plug it in and select the manufacturer’s Performance mode. Windows Battery Saver and many “balanced” laptop profiles can hold the CPU at a low power state, which creates sluggish transitions even when the GPU is barely working. Keep the laptop on a hard surface, too; thermal throttling often looks like a game-specific FPS problem.
Fix crashes that happen at launch or during loading
A crash before the main menu usually points to files, drivers, permissions, or a graphics initialization conflict. Start by launching the game with every overlay disabled and any custom launch option removed from Steam. If you previously added a command copied from a forum, delete it and test the default launch path.
Reset configuration without touching your saves
Corrupted display settings can crash a game before it has a chance to show its options menu. Close Steam, then look for Citizen Sleeper 2 configuration data in the user profile folders used by the game. Back up the folder before renaming it to something like CitizenSleeper2_backup. Relaunching should create fresh settings. Do not delete the entire folder until you have confirmed where Steam Cloud stores your save data.
Steam Cloud can restore a broken configuration or an older save after you remove it. If the crash returns immediately, temporarily disable Steam Cloud for Citizen Sleeper 2, create a local backup of your saves, reset the configuration, and test again. Re-enable Cloud only after the game reaches the menu and loads normally. Never overwrite a healthy local save with an unverified cloud copy.
Check Windows security and runtimes
Windows Security’s Controlled Folder Access can block a game from writing settings or saves. Rather than disabling antivirus protection entirely, add the game executable as an allowed app if Windows identifies it as blocked. Also install pending Windows updates and the current Microsoft Visual C++ Redistributable packages from Microsoft’s official download page.
For an official baseline, check the Citizen Sleeper 2 Steam page for current requirements and update notes. The developer’s official site is also worth checking before assuming a crash is caused by your PC.
Stop low FPS and stutter after the game launches
Low FPS needs a different diagnosis from crashing. Open Task Manager or use a trusted monitor and watch GPU usage, CPU usage, temperatures, and RAM while reproducing the drop. High GPU usage means resolution, effects, or upscaling are the first levers. Low GPU usage with a busy CPU points toward background programs, power limits, or a frame-pacing issue.
| Symptom | Likely cause | First fix | What success looks like |
|---|---|---|---|
| Low FPS everywhere | Resolution, power mode, or outdated driver | Plug in laptop, update driver, lower resolution one step | GPU load becomes stable and FPS rises consistently |
| Brief hitch when entering a scene | Shader or asset compilation | Repeat the same transition after a restart | Second pass is smoother than the first |
| Stutter only with overlays enabled | Capture or overlay injection | Disable Steam, Discord, and GPU overlays | Frame pacing improves without lowering quality |
| FPS drops after 20–30 minutes | Thermal throttling or memory pressure | Check temperatures, close browsers, improve airflow | Clock speeds remain steady during play |
| Menu is smooth, gameplay is uneven | Effects, transitions, or display mode | Test fullscreen, then reduce effects and post-processing | Location changes stop producing long spikes |
Browser tabs matter more than people expect. A video stream, dozens of tabs, RGB software, and recording tools can consume several gigabytes of RAM while also waking the CPU every few seconds. Close them for one clean test. If the result improves, add programs back individually rather than blaming Citizen Sleeper 2 for a system-wide resource squeeze.
AMD and NVIDIA users should also check that the game is using the dedicated GPU. In Windows, open Settings > System > Display > Graphics, add the game executable, select Options, and choose High performance. This is especially important on hybrid laptops, where a game can launch on integrated graphics despite appearing to run normally.
Steam Deck and final troubleshooting steps
On Steam Deck, stay conservative: use the game’s default resolution, cap the system to 30 or 40 FPS, and avoid stacking the SteamOS frame limiter with several third-party limiters. A 40 FPS cap works best with a 40 Hz display mode; otherwise, 30 FPS is the safer target for consistent frame pacing. If a Proton update introduces a crash, test the game’s default Proton version before experimenting with Proton-GE.
Desktop players should test with a clean boot if the issue remains. Disable nonessential startup applications through Task Manager, reboot, and launch Citizen Sleeper 2 before opening browsers or utilities. A clean boot that fixes the problem confirms a software conflict, not a failing GPU. Re-enable services in groups until the culprit appears.
Finally, report repeatable problems with useful evidence. Include your CPU, GPU, RAM, Windows version, driver version, display mode, resolution, whether overlays were disabled, and the exact trigger: startup, loading a save, entering a location, or ending a cycle. Attach crash logs if the developer requests them, but never post personal save files publicly without checking their contents.
The best performance target for Citizen Sleeper 2 is boringly effective: stable 60 FPS at native 1080p, V-Sync on, overlays off, and a current driver. If your hardware can’t hold that profile, lock 30 FPS rather than accepting constant spikes.

And before changing anything risky, back up your saves—the fix should get you back aboard The Bounty, not erase your run.
