What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
For Kingdom Hearts games on PC, start by updating the game and graphics driver, restarting your computer, and testing one input device at a time. If a crash persists, Square Enix recommends reinstalling the affected game and contacting support with system diagnostic files. For low frame rates, compare your PC with the requirements for the specific game you are playing; the published requirements cited here apply only to Kingdom Hearts HD 1.5+2.5 ReMIX, not every title in the collection.
Identify which game and symptom you have
The Steam bundle Kingdom Hearts Integrum Masterpiece includes Kingdom Hearts HD 1.5+2.5 ReMIX, Kingdom Hearts HD 2.8 Final Chapter Prologue, and Kingdom Hearts III + Re Mind. Troubleshooting and requirements can differ by game. Note the exact title and whether the problem is a crash, failure to launch, unreliable controller input, or persistently low FPS before changing settings.
Square Enix’s support checklist is the game-specific starting point for crashes. Its controller-support page describes partial support for several controller types. For FPS, the official material gives requirements for HD 1.5+2.5 ReMIX and general Steam performance advice, but does not establish one verified low-FPS fix for the entire collection.

- If the problem continues, reinstall the affected game.
- If it still crashes or will not launch, contact Square Enix support and attach Msinfo and Dxdiag files.
These are troubleshooting steps, not confirmation that a particular cause or known game bug explains every crash. If the issue remains, include the game title, what happens, and which steps you tried when contacting support.
Create the Msinfo file
- Open Start, type
msinfo32, and open System Information. - Wait for the information to load, then select File > Save.
- Save the resulting
.nfofile. After saving, wait at least a minute before closing System Information.
Create the Dxdiag file

dxdiag, and open the DirectX Diagnostic Tool. - Select Save All Information and save the resulting file.
Troubleshoot controller problems
Square Enix says Xbox, PlayStation DualShock, PlayStation DualSense, and Steam Input controllers have partial PC support. You may need a keyboard and mouse to navigate some parts of a game. See the controller support information before treating incomplete input as a broken controller.

If movement is erratic or inputs seem to conflict, test with one input device connected at a time. Square Enix’s separate PC guidance for erratic movement describes possible conflicts involving another connected controller, joystick, or steering wheel, including devices that are not being touched. It is general troubleshooting advice, not a confirmed diagnosis for every Kingdom Hearts game.
- Check that the controller is connected properly and try its available calibration options.
- Temporarily disable third-party controller or remapping software, then test again.
- Disconnect other controllers, joysticks, and steering wheels; reconnect only the device you want to use.
- If needed, use Windows Game Controllers to recalibrate. The Square Enix guidance also suggests restarting with the controller disconnected and removing existing controllers through Control Panel.
- Test a supported input method, including keyboard and mouse where the game requires it.
These steps help isolate configuration conflicts; they do not establish that replacing a controller will solve the problem.

Check low frame rates
First compare your PC with the requirements for the particular game. The following figures are the requirements and performance targets on the Steam listing for HD 1.5+2.5 ReMIX, accessed in 2026. They are published targets, not measured benchmark results or a guarantee of performance.
| Listing category | Operating system | Processor | RAM | Graphics | DirectX and storage | Listed target |
|---|---|---|---|---|---|---|
| Minimum | Windows 10 64-bit, version 1909 or later | Intel Core i3-3210 or AMD A8-7600 | 4 GB | NVIDIA GeForce GTX 750 or AMD Radeon RX 460 | DirectX 11; 60 GB available storage | 30 FPS at 1280×720 |
| Recommended | Windows 10 64-bit, version 1909 or later | Intel Core i3-3210 or AMD A8-7600 | 8 GB | NVIDIA GeForce GTX 750 or AMD Radeon RX 460 | DirectX 11; 60 GB available storage | 60 FPS at 1920×1080 |
Do not apply these specifications to HD 2.8 Final Chapter Prologue or Kingdom Hearts III + Re Mind; the cited listing covers only HD 1.5+2.5 ReMIX. Meeting listed requirements does not guarantee a particular frame rate. Steam’s general FPS guidance notes that performance depends on multiple machine-specific factors and that changing video options may help, but it is not a Kingdom Hearts-specific fix list.

Try reversible performance checks
- Check the requirements for the exact game you are playing. For HD 1.5+2.5 ReMIX, compare your system with the listing above.
- Install available game updates and current graphics drivers, then restart the PC.
- Close unusually demanding background applications and test the game again.
- Lower a graphics option or resolution, one change at a time, and check whether FPS improves. These are general PC troubleshooting steps, not verified fixes for every Kingdom Hearts title.
If performance remains poor, record the game, your PC specifications, the settings you changed, and the observed symptom. If the game also crashes or instability persists, follow Square Enix’s crash process and send the requested diagnostics to support. The Steam listing’s technical-support route directs players to Square Enix support.
