Graphics Card not Recognizing Minecraft

[3derpderpderp]

I have an MSI Radeon 7870, but because Minecraft has so little graphic intensity, the GPU clock doesn't go up and it sticks around 300MHz and causes the game to lag. Is there a power setting or a way I can get the 7870 to recognize that I'm playing minecraft?

you can turn off vsync which will remove the cap of 60 fps and it will try to render as many frames as it can.

also try it in full screen. Im told the button for that is f11.

Have you tried switching v-sync off? I was having lag issues with my new 280X and it was just v-sync limiting the frames. I don't know if it is the same issue your describing but maybe give it a try. Sorry if its not the solution.

I've tried turning off vsync, changing control panel power settings, using OpenGL rendering, and I have the latest drivers so I'm not sure how to keep the card at a higher clockspeed during minecraft.

does your system include on-board graphics, maybe the game is trying to use that instead of the GPU?

No I have an Athlon 750k which is forced to be over 2600MHz at all times. Is there a way I can set a minimum clock speed for my GPU?

 

[Haigz]

have you tries using the msi overclocking software? I think its called afterburner but that could be something else. You should be able to turn up clock speeds in that. If that doesn't work, there is a way to turn it up in the bios but you would have to google the motherboard to find out how.

I tried afterburner but I wasn't able to set a minimum clock speed. I'll try out the bios idea tomorrow but I think I'm going to have to get a texture pack or shaders to trigger the GPU so its clock speed goes over 300mhz

Ok, let us know how the bios goes.

The bios didn't have anything that would help me. Hopefully I can find a way to lock the GPU on 3d mode so that it can't be in idle state when I play minecraft.

Is your graphics card plugged into a pcie *16 slot? maybe your motherboard is limiting the GPU?

Yes it is in a x16 slot. It is a mini-itx motherboard. The problem at this point is figuring out how to get the GPU to run at a constant clock speed so that it doesn't downclock itself during minecraft. Maybe I should try Sapphire Trixx or HIS iTurbo?

yeah that might work, I honestly have no idea why your graphics card isn't recognising it. Does this happen in any other games? Maybe your graphics card has a fault because it should not be throttling down and letting your game suffer.

I researched it some more and apparently its a common problem with the Radeon HD 7xxx series not recognizing minecraft and sticking in 2d mode. There isn't an easy way to force it into 3d mode so I think I'm out of luck.

I'm just gonna throw another possible solution your way, but have you ensured that Java is updated? Make sure that your version of Java is the correct one was well.

Yeah I checked and I do have the latest and the correct version. Do you know a way to force 3d clocks instead of 2d clocks?

I too am having this problem, with a r7 265 (7850)

I can run Bf4 on high at 60 frames, but minecraft on high gives it 30 frames. Anyone fixed this problem yet?

Edit: spelling issues.
