Java 8 clients can lag or stutter when you run them for many hours—especially during teleporting or loading large areas. If your client regularly crashes, it often means Java lacks allocated memory.
32-bit Java caps memory at about 248 MB on 64-bit PCs. That limit can’t support modern game demands. Follow this guide to check your heap space, install 64-bit Java, and apply extra performance tips.
Check Your Heap Space
- Press the tilde (~) or backtick (`) key to open the Developer console.
- Type “heap” and press Enter.
- This should return approximately a quarter of your PC’s total RAM.
If this seems to be in order on your client, skip to Apply Additional Performance Tips. Otherwise, proceed to Install 64-Bit Java.
Install 64-Bit Java
- Close all BlissScape clients and launchers.
- Go to the Java Manual Downloads page.
- Download Windows Offline (64-bit).
- Install the downloaded file.
- Restart your client and recheck the heap value.
If the heap value stays below one quarter of your RAM:
- Download Windows Offline (32-bit) from the same page.
- Install it, restart your client, and check the heap again.
Apply Additional Performance Tips
Use these steps if 64-bit Java doesn’t solve your crashes:
- Update Java and your graphics drivers manually.
- Swicht to OpenGL or DirectX in the Custom Graphics Settings. OpenGL runs better on NVIDIA cards than on AMD cards.
- If OpenGL still fails, perform a clean install of BlissScape.
- The Java uninstall tool can help you detect old Java versions to avoid conflicts.
- JarFixer is a program that links .jar files on your computer to Java, if for any reason your computer is failing to connect the two properly. This often fixes graphical and client window issues.
