A PC game demo that crashes, stutters, or ignores a controller is best troubleshot one change at a time: check the demo’s requirements, update Windows and graphics drivers from official sources, verify the game files, and test with overlays and recording tools off. For controller problems, isolate the controller and check the game’s per-launcher input settings before assuming the hardware is faulty. Because no specific demo or PC setup is identified here, treat these as general checks and follow the game’s own support instructions for title-specific fixes.
What should I check before troubleshooting?
First, note what the problem looks like and when it happens. A demo that never opens, one that freezes after several minutes, intermittent hitching, and a controller that works everywhere except one game point to different possibilities. A few observations will help you avoid changing several things at once and make any later support request more useful.

- Record the symptom: Does the demo fail at launch, freeze during a particular action, close without a message, stutter during play, or stop responding to controller input?
- Note when it began: Record whether the issue started after a Windows update, graphics-driver change, game update, or change to controller or launcher settings.
- Check the setup: Find the demo’s exact store page and published minimum and recommended requirements. Note your PC’s relevant specifications and the launcher you use.
- Make one change at a time: Retest after each reversible change. If you change settings, update a driver, and close several apps all at once, you will not know which action mattered.
Do not assume that a fix reported for another demo applies to yours. The launcher, game, PC hardware, and exact fault all matter.
Why does my PC game demo keep crashing?
Crashes can arise from a mismatch between the demo’s requirements and the PC, damaged or missing game files, a background conflict, or a game-specific problem. None of those possibilities is a diagnosis by itself; work through the checks below before reinstalling or making riskier system changes.

1. Compare your PC with the demo’s requirements
Use the requirements published for the demo, not assumptions based on the full game or another title in the series. A PC below minimum requirements may run poorly or fail to start. Meeting minimum requirements does not guarantee smooth performance; if the PC falls short of the recommended specification, try lower graphics settings and restart the game.
Where the demo offers graphics settings, start with a lower preset or reduce demanding options, then test the same scene or action that caused the problem. If you cannot reach the settings menu, see whether the game’s support page provides a supported way to change them. Avoid applying generic configuration-file edits without title-specific instructions.
2. Restart after system or driver updates
Install available Windows updates and update the graphics driver through the GPU manufacturer’s official software or support pages. Restart the PC after applying updates, then launch the demo again. Avoid third-party driver-download sites: the troubleshooting guidance here supports official sources, not downloads from unrelated sites.
If the problem began immediately after an update, record that timing. It may help the game’s support team distinguish a new compatibility issue from a longstanding one.
3. Verify the demo’s files before reinstalling
If you installed the demo through Steam, use Steam’s file-verification option for that game. Capcom describes Steam’s process as scanning downloaded files, checking their checksums against the server’s file manifest, and reacquiring files that are missing or do not match. The precise interface and wording can differ between launchers, so use the launcher’s own instructions rather than assuming every store works like Steam.
File verification is a reasonable step before a full reinstall because it checks the existing installation for mismatches. It does not prove that every crash is caused by a bad file, nor does it fix every game bug.

Capcom’s Steam troubleshooting guide covers requirements, graphics settings, background applications, file verification, and a caution about shader-cache changes.
4. Test for a background-app conflict
Temporarily disable overlays and recording tools, and close resource-heavy applications. Retest the demo, then re-enable or reopen tools one by one if the problem is gone. This controlled approach can reveal a conflict without leaving you guessing which app was involved.
Do not broadly disable Windows protection to get a demo running. If you suspect the game executable was blocked, check Windows Security notifications and confirm that the demo came from a legitimate source. Only follow a specific, trusted game-support instruction about a security setting; do not turn protection off as a general troubleshooting step.
5. Look for a pattern in longer-session crashes
If the demo launches but crashes during play or after a longer session, lower the graphics settings, close resource-heavy applications, and check CPU and GPU temperatures. If the PC is overclocked, test at its default hardware clocks. Change one factor at a time so that any improvement—or lack of improvement—is informative.

How do I fix stuttering in a PC game?
Start with the requirements, graphics settings, and PC load; then test with overlays and recording software disabled. Stuttering has multiple possible technical causes, so a hitch by itself does not show which one is affecting a particular demo.

Check system load and settings
- Compare your PC with the demo’s minimum and recommended requirements.
- Lower graphics settings if the PC is below recommended specifications, then restart the game if needed.
- Close resource-heavy applications and check whether another process is using CPU, memory, or disk heavily.
- Disable overlays and recording software for a controlled test.
- Repeat the same in-game activity and note whether the hitch changes, remains, or occurs at a different point.
These checks can help separate a performance constraint or background-app conflict from a fault that appears tied to one particular scene or action. They cannot establish a root cause without more information about the game and PC.
Why can stuttering happen?
NVIDIA’s developer presentation discusses shader compilation, video-memory oversubscription, resource management, queued frames, and improper queries as possible sources of stutter in games. These are explanations of mechanisms—not a finding that any one of them is the cause in your demo. The presentation is technical context, not a consumer fix list.
A shader cache may be implicated in some title-specific cases, but deleting cache files is more invasive than checking settings, system load, and overlays. Do not treat cache deletion as a universal first step. Follow current instructions from the game’s support team or the graphics-chip maker if they recommend it for your specific issue. Capcom’s troubleshooting guidance also cautions that cache-related changes are not a general-purpose first action.
NVIDIA’s presentation on stuttering in game graphics describes those possible technical causes; it does not diagnose an individual PC game demo.
Why won’t my controller work in a Steam game?
A controller problem may come from the game’s support or mapping, a per-game Steam Input setting, another connected input device, or the controller or connection itself. Test the configuration first: a controller that works in Windows or other games is less likely to need replacement than one that fails across applications, though neither observation alone proves the cause.
1. Isolate the controller
Close the demo, connect only the controller you want to test, and relaunch the game. Temporarily disconnect other controllers and input devices such as joysticks, steering wheels, or handbrakes if the game keeps switching between inputs or behaves strangely. This helps determine whether another device is interfering with input selection.

2. Check Steam’s per-game controller setting
In Steam, open the game’s Properties and select Controller to find its controller setting. A manual for one Steam game recommends trying Disable Steam Input when a PlayStation or Xbox controller is not recognized. Another publisher FAQ recommends disabling Steam Input as a diagnostic for input delay. Try the setting as a per-game test, then restart Steam or the computer and check again.
This is not a universal recommendation: the right setting can depend on the game and controller. If changing it makes things worse, restore the previous setting. The game manual’s advice is specific to its own game; its guidance is an example of a possible test, not proof that the same setting is right for every demo. See the Steam-hosted controller troubleshooting manual and Dotemu’s guidance on reproducing technical issues.
3. Separate a game-specific problem from a wider controller issue
If the controller works in Windows or other games but not the demo, check whether the demo supports it, whether its controls need mapping, and whether the launcher’s per-game setting is involved. If it fails across applications or behaves erratically when connected another way, investigating the controller or connection becomes more relevant. The available guidance does not establish a particular cable or replacement model, so do not buy hardware before these checks point toward a device problem.
When should I reinstall the demo or change Windows settings?
Reinstalling is not the first step: verify files through the launcher before removing the demo. A reinstall may be worth considering only if ordinary checks do not help and the game’s support instructions recommend it. The exact reinstall process and any saved-data implications depend on the launcher and game, so check their guidance before removing files.

- The demo’s name, launcher, and PC specifications relevant to its published requirements.
- Whether the issue occurs at launch, during a particular action, after a longer session, or only when using a controller.
- The steps immediately before the crash, freeze, hitch, or input problem, in the order they happened.
- Any error text and the approximate time of a crash; if available, include the relevant application-error details from Event Viewer.
- Which troubleshooting changes you made and what happened after each one, including whether the controller works in other games or Windows.
Follow the demo’s support page for any requested logs or reporting format. Telltale’s guide discusses checking Event Viewer for application errors, while Dotemu’s article explains why steps to reproduce a technical issue are useful. A clear report helps support staff tell whether the problem is repeatable and what evidence to investigate; it does not guarantee that the cause can be identified from the report alone.
How do I narrow down the likely cause?
Use the pattern of the fault to choose the next check—not as proof of a diagnosis.
| What you observe | Useful next check | What it may help distinguish |
|---|---|---|
| The demo will not launch or crashes immediately | Check its requirements, restart after official Windows or graphics-driver updates, and verify files through the launcher. | A system-specification gap, an update-related issue, or a file mismatch. |
| It runs, then crashes during play or a long session | Lower graphics settings, close resource-heavy apps, check CPU and GPU temperatures, and test at default clocks if overclocked. | Whether settings, system load, heat, or overclocking coincide with the crash. |
| It hitches during play | Check requirements and system load; disable overlays and recording software for a controlled retest. | Whether the issue changes when settings or background activity changes. The hitch alone does not identify its technical cause. |
| The controller is not recognized or input switches unexpectedly | Connect only the controller being tested, then inspect the game’s per-game launcher setting. | A conflict with another input device or a game/launcher configuration issue. |
| The controller fails in other applications too | Investigate the controller or connection across applications before focusing only on the demo. | Whether the problem extends beyond the game; this still does not by itself prove hardware failure. |
How do I fix a demo without making troubleshooting harder?
Keep a short change log: write down what you changed, when you changed it, and whether the same failure happened afterward. If a setting makes the issue worse, restore it before continuing. This is especially useful when testing overlays, controller overrides, graphics settings, or other per-game options.
Use the least disruptive checks first: requirements, updates from official sources, a restart, file verification, and a controlled test with background tools closed. Escalate to title-specific support for steps that affect caches, security settings, or broader Windows configuration. A generic guide can help organize the investigation, but only the game’s own support information can address instructions unique to that demo.
For additional publisher guidance, see Warner Bros. Games Support’s Steam troubleshooting page, which also recommends checking settings and background applications. Its instructions are publisher guidance, not a diagnosis for an unrelated demo.
Frequently Asked Questions
Can a demo crash even if the full game would run on my PC?
A demo may have its own published requirements, so check the demo’s store listing rather than assuming the full game’s specifications apply. If the requirements are unclear or differ across listings, ask the game’s support team which specification applies to that demo.
Do these 3 things before closing this tab:
1Repair Windows errors before they cause bigger problems2Scan for outdated or missing drivers - takes under a minute3Clear out junk files and repair common Windows errorsShould I delete a game’s shader cache to stop stuttering?
Not as a first step. Cache changes are more specific and potentially disruptive than checking requirements, settings, system load, and overlays, so use current instructions from the game’s support team or graphics-chip maker.
Will buying a new controller fix input delay in a Steam demo?
Not necessarily: a per-game Steam Input setting or the demo’s own mapping can cause trouble even when the controller works elsewhere. Check the configuration and test with other input devices disconnected before deciding the controller itself is faulty.
What does an Event Viewer error prove after a game crash?
An application error near the crash time can provide useful details for support, but it does not necessarily identify the underlying cause. Include the timing and relevant error text with the steps that led to the crash.
