AMD not working with Java.

KetchupSniper · Jul 13, 2013

Hello.
I recently got a new card, the AMD Radeon HD 7750 1 GB. I know this isn't the best of cards but it's one that actually fits in my PC.
But anyway onto the issue. This card does not work with Java. So, when I launch Minecraft, my PC decides to use my integrated card. You cannot add programs from the Catalyst Control Center. Does anybody know a way of getting Minecraft to use my GPU?

I have tried that, it doesn't work

Are you running both cards at once. If so, make sure that your primary display is the screen connected to the 7750(can set it In Windows display properties).

No way for the card it self to "not support" java.

I know, I worded it a bit wrong I meant it isn't used. And I connect my screen to motherboard not directly to my card, as that doesn't work. Also how do I make it the primary display the one connected to the 7750?

The problem is that it is likely not recognizing Minecraft as a direct3D game, and therefor not using your discrete card. I found a possible fix a search: http://wasil.org/minecraft-ati-dell-switchable-graphics

i too have an AMD and java works for me :
Java Verify failure unable to Configure Java Control Panel does not open ( Fix : )
this is a regular ( windows 7 bug related ) problem after successful installation of Java ( jre ) and fresh installation of Windows7 64bit or 32bit on my laptop or desktop. what worked perfectly for me was setting COMPATIBILITYMODE=WINDOWSNT to make windows launch the JP2LAUNCHER.EXE and JAVAW.EXE files properly.
jp2launcher.exe windowsNT compatibility solves Java Verify failure problem at https://www.java.com/en/download/installed.jsp
javaw.exe windowsNT compatibility solves unable to open or Configure Java Control Panel problem.

* search for JAVAW.EXE inside c:\program files\java\....\bin
or c:\program files(x86)\java\.....\bin\
* right-click mouse on JAVAW application icon logo
* click PROPERTIES
* click COMPATIBILITY
* tick the checkbox at COMPATIBILITY MODE
* choose WINDOWS NT service pack
* click APPLY or click OK
Now, the Configure Java Control Panel will start opening and working.

* search for JP2LAUNCHER.EXE inside c:\program files\java\....\bin
or c:\program files(x86)\java\.....\bin\
* right-click mouse on JP2LAUNCHER
* click PROPERTIES
* click COMPATIBILITY
* tick the checkbox at COMPATIBILITY MODE
* choose WINDOWS NT service pack
* click APPLY or click OK
Now, the Verify Java will be successful at https://www.java.com/en/download/installed.jsp

if we find 2 or 3 versions of JP2LAUNCHER and JAVAW when we search, then we must repeat the above for all of them.

in the Configure Java Control Panel Advanced tab we can set "Do not check" certificate revocation and disable security verification. and in the Security tab we may Edit Site List... for the Exception Site List ( add URLs to unblock sites )
