Radeon HD 7970 Low FPS in Minecraft ONLY

Hey! There are probably alot of questions about this already. But fuck. None of them helped so far.(repost. The last one apparently died and I'm in serious need of help)

So. I just got my 7970. I can run BF3 with stable 80+ fps with ultra settings. But whenever I try to play Minecraft (singleplayer) I get around 150 fps top. Whenever I go online, it doesn't matter if I have bad or good connection with the server. I still get top 60 fps.. I know I know. 30 fps is enough. But it isn't. I have a 144Hz monitor so It's really annoying not having dem 140+ fps. I just think this is really weird as I got about 200+ stable fps on Minecraft with my old GTX 560. I have the latest cataclyst drivers and stuff. Latest Java. 64 bit for my 64 bit OS. I have "forceclocked" the card to keep the gpu clock at 955Mhz. When I play Minecraft in maximized (1080p) gpu load maxes 60. But is average on 25 - 50%

Specifications;
-PowerColor radeon HD 7970
-Intel Core i5 3470 @3.20Ghz
-16gb 1600mhz ram (4x4gb)
-MSI B75MA-P45

minecraft is really more cpu bound so the GFX isnt doing it any harm. its probably just the way minecraft is, liking some setups, hating other more powerful ones...

Perhaps you could increase the virtual memory until you have no lag.
See if that helps.

I really dislike when people say Minecraft isn't affected in larger amounts by the GPU. There's a reason i have 200 fps with gtx 560 and 100 with 3850.. I was really not hoping for this answer. But then again. Minecraft is kinda retarded and the devs are braindead.

Allocate more RAM? What difference would that make?

That wouldn't make any difference, you already have more RAM than needed for gaming anyway

If it's capped at 60 then it sounds like Vsync may be enabled somehow

The thing is, I'm not capped. I can go above 60fps it's just that i barely can. When playing singleplayer i sometimes barely get 150fps and then get alot of fps dropping. Even when the world isnt loading..

A similar post to this one

Yeah.. I dunno. I don't think I'm capped. I think it has something to do with that Minecraft don't use too much gpu power and therefor it's mistaken for a 2D software or something. I'll check BIOS stuff and see if maybe my computer switchea to Intel HD graphics. If I'm not mistaken that's the FPS I get using Intel HD

The Intel HD would have been disabled the second the 7970 was placed into the slot

Hmm.. I have two stationary computers. And I remember seeing a overwrite graphics card or disable intergrated graphics if pci-e is occupied. As I said earlier I'll look into the BIOS once I come home from school.

well there is a possibility of some power settings disabling the PCIe GFX in favour of the integrated solution when there is low graphics load. i know i have that on my laptop with a quadro. maybe something similair with you

That's a desktop, and the Intel HD graphics are disabled since the cable outputting the picture is connected to the Radeon 7970 (and it should automatically disable it in BIOS/UEFI), the IGPU is called onboard for a reason

On laptops it works like this, Intel HD for everyday programs, the dedicated for graphical intensive applications, it's different than a desktop

For your situation on the laptop it would be using Nvidia Optimus technology

My power settings are set to performance. I even checked everything manually to be set at performance. But to be perfectly honest I think it's something with the Minecraft software. Either Minecraft itself. Java. DirectX or other dumb software that is required for gaming.. I wish all these softwares could just be bunched into one installation upon W7 installation. I know most of them gets installed upon game installation!

Oh yeah.. Didn't think of that. Well I coud try changing output port?

It's already plugged into the 7970, changing ports wouldn't do anything different lol

The 7970 can be confirmed to be working properly as seen with the BF3 framerate and probably other games as well so it would probably just come down to Minecraft itself

I think this is really weird concidering some people got their 7970 working with Minecraft by just reinstalling and stuff.. Oh well I'm gonna re-install windows once I get a SSD anyways. I used Minecraft for the most part as a game to test and see how high FPS I can get in an actual "good" game.

After some humming about I found that League of Legends in ultra settings is really low FPS too. (40 - 60). And if I open up amd overdrive whilst playing there's a message saying "Clock settings are applied only when then GPU is running in high-performance mode" so I'd assume that's the problem? The card not going into high-performance. So it's like "meh" shit games no need to perform!
