Minecraft Forums

Hello I have got a new laptop that has Intel i7-6500u cpu (Intel HD Graphics 520 integrated) and AMD Radeon R5 m330 GPU

When launching Minecraft for the first time it runs on the integrated graphics (it worked but a bit on the slow side)

so i checked amd settings and added minecraft so it runs on AMD gpu

Result: when entering a any level, the whole pc freezes and becomes completely unusable until I hard reset it

Question is how to run it on the gpu with no problems?

meanwhile all other games are working seamlessly on the gpu (like NFS, CoD..etc)

There are no screenshots because as I said the computer freezes

More detailed information: (dxdiag)

Your AMD driver is two years old, I'd say try updating it, see if that helps.

As far as that goes, so is your Intel driver.

Here's the AMD driver updater link:

http://support.amd.com/en-us/download/auto-detect-tool

And here's the one for Intel:

http://www.intel.com/p/en_US/support/detect?iid=dc_iduu

Oh well... I thought Windows update is taking care of AMD drivers as it takes care of Intel's (taking care badly anyway ..intel is also outdated)

because I saw yesterday that the UI of Radeon Settings has changed completely to the new one

Thanks I will update them and inform you later about the result

by the way i am not using the auto detect tool you provided because it crashes Windows always .. maybe they need to update it ..(BSOD: Thread stuck in device driver)

so I went to my gpu's downloads page...

I have downloaded the amd amd driver offline installer

It did the same as the online tool

After clicking "Accept and install" and waiting for a couple seconds.. it crashes

I have updated both successfully eventually

but Minecraft still freezes the computer completely when i enter any level

Here's the full information DxDiag (Current)

and this was the old one DxDiag (old)

Strange that the computer crashes just trying to update a video driver. That's a red flag that something strange is going on, but who knows what it could be? But with the drivers updated and no crash report since the computer just locks up, I don't know what else to tell you, aside from asking AMD in their support forums.

So.. looks like this is not going anywhere

Also I couldn't get Minecraft off amd... since i added it 1st time, it always runs on gpu (seen in task manager) even though i removed it from amd settings (also nothing in switchable graphics section)

EDIT:

Maybe it is because java online installer gave me the x32 jre??... Why doesn't it install the x64

Ill install x64 manually and see if it fixes it...

EDIT 2:

It worked... The problem was that java online installer didn't install x64 jre, but instead it installed x32 thus making compatibility problems with AMD

Yes, that's a problem. Never use the Java online installer, always use the offline 64 bit, as Minecraft needs 64 bit in order to access memory correctly or something like that. You can also install the 32 bit Java, but it won't effect Minecraft, but other programs on your system that do use Java and need 32 bit would be helped by having it updated.

It's also a good idea if it asks, to uninstall any old versions it finds, unless you have a specific reason to keep an old version of Java around, like for a utility that needs it, but it should really be updated to use the new Java if at all possible.

really does anyone still have a x32 computer to install x32 jre :/

even my old dusty pc is running on x64

The performance difference comparing an application running on a 64-bit platform versus a 32-bit platform on SPARC is on the order of 10-20% degradation when you move to a 64-bit VM. On AMD64 and EM64T platforms this difference ranges from 0-15% depending on the amount of pointer accessing your application performs.

The default heap size for all 32-bit J2SE implementations is 64MB. We have adjusted the defaults for 64-bit implementations to be 30% larger in order to make up for the increased size of Java objects due to larger native pointers. Remember that Java objects contain class and lock pointers so even if you create Java objects which contain only integers, each object takes up additional memory.

I have a 32 bit OS and have never had any issues like this; it is only a problem when you try running 32 bit Java on a 64 bit OS since the OS has to emulate a 32 bit environment. Otherwise, 32 bit Java is actually slightly faster and needs less memory:

Interesting

Some browsers are also 32 bit and need 32 bit Java.
