Low FPS on minecraft / crashes with R9 290X

Myntekt · Sep 12, 2014

So I just bought a R9 290X and when I try to play minecraft, I have a small amount of FPS. Then, when I switch for example to Google Chrome, and reswitch back to minecraft, e stops working.
How can I fix this?
PS.: No, I didn't buy this GPU to play minecraft, I also play other games, such as Battlefield 4.

This didn't happen when I was using my 560 Ti.

Full specs?

Run fraps, tell us what your average fps is in MC.

I can click F3 to see my FPS. The FPS aren't that low normally, but they are lower in a certain spot.
It crashed when I switch pages. My PC is good enough for the game by the way. I7 3770K OC to 4,3Ghz, 16GB ram, 250SSD.

EDIT: I just realized that I don't even have to be ingame (I can be on the menu, where you choose Single or Multiplayer) for the game to crash.

I get up to 250. With my GTX 560 Ti I would sometimes get 300-400 fps, but I didn't crash and I crash now.

Hello,

What PSU are you using (make/model)? For 290x, a very good 650 W PSU is a must (at least 45Amps for the +12V rail, or 2x25Amps for dual +12V rail).

Myntekt · Sep 12, 2014

I just bought/installed a new PSU too. It's this one: http://www.evga.com/Products/Product.aspx?pn=110-B2-0750-VR

EDIT: Every game works fine, I guess, only minecraft crashes

moozilbee · Sep 13, 2014

Be more specific, does the game crash whilst your playing, or when you switch to another window? If it's switching to another window, I believe that often happens with some games, the solution would be to either play in windowed mode, or see if you can somehow run the game in borderless window mode.

Also, why do you think 250fps is low?

Myntekt · Sep 13, 2014

I was specific. I'll explain it a little better anyway. I get 250fps tops with a R9 290x, whilst with a GTX 560ti, which is worse, I could get up to 400fps. In a certain area, that has a lot of item frames and a lot of different blocks, I would get 60-100fps with the GTX 560Ti, whilst I get 15-30fps with my R9 290x. The game crashes when I switch from minecraft to something like google chrome, and then switch back to minecraft. I do not play on fullscreen, since minecraft isn't something that I think requires that. In my opinion, a R9 290x shouldn't do this, and should get WAY more fps.

I just tested, and for now it hasn't crashed the way it would before. Still low FPS though.

Have you tried going through the different drivers that are available for that card?

moozilbee · Sep 14, 2014

Try going updating your drivers as Mousemonkey said, it might fix the FPS issue.

Myntekt · Sep 14, 2014

I got the GPU some days ago, and this error occurred on that same day. I guess it's not the drivers, they were up to date.

moozilbee · Sep 14, 2014

Did you install the drivers from a disk or did you download them online?

Myntekt · Sep 14, 2014

Online

Its a known bug that minecraft may not cause the GPU clocks to increase.

Can you monitor your GPU clock while running minecraft and see if it switches to 3d mode?

Myntekt · Sep 14, 2014

smeezekitty :

How do you do that?

smeezekitty · Sep 14, 2014

Use something to monitor the clocks. I think CCC has that feature but my favorite tool is MSI afterburner

Myntekt · Sep 14, 2014

smeezekitty :

I do have that (MSI Afterburner), but where exactly do you check that?

EDIT: minecraft just stopped working again

smeezekitty · Sep 14, 2014

MSI AB should have a small monitor window that should show the core and memory clocks.
When you are idling with no game or video playing it should be at its "idle" clock rating.

Now when you start Minecraft it *should* increase its clock.

If it doesn't then you are experiencing that bug. There are several work aorunds but first
you need to determine if that i s the cause

Myntekt · Sep 14, 2014

smeezekitty :

I'll try that out.

Myntekt · Sep 14, 2014

The core clock doesn't change from 1030. Gaming or not. Not on minecraft, not on battlefield 4.

smeezekitty · Sep 14, 2014

Wait? Are you saying it is in 3d mode all the time?
What about on a clean boot?

Myntekt · Sep 14, 2014

smeezekitty :

I don't even know what 3d mode is. I'll clean boot the pc to test it.

Myntekt · Sep 14, 2014

Yup, still the same 1030 on the core and 1250 on the memory
