AMD 14.4 drivers, still underclocking...

Fresh install of windows, installed the AMD 14.4 drivers for the R9 290. Unigine Valley seems perfect, it will hold a solid core clock at whatever I set it to but actual gaming seems exactly the same. Crysis 3 for example; even with a mild overclock of 1100 / 1450, it will clock that back from anywhere between 770mhz - 950mhz... It seems the more graphically intensive the process, the further the declock is. Even no overclock at all, in Crysis 3 the core clock is declocked down as low as 770mhz.

Is anyone else still experiencing this?

No I haven't.... Should I be setting 2d to run a full o/c setting? ... Surely it should be holding the stock clock speed with no overclock at all?
 
Yes, I increased the power limit to +50%

CPU i5 2500K @ 4.4ghz
If you have already increase power limit to 50%, the only time that the GPU would down clock (when temp is fine) is that not enough workload is given to to it, thus it would downclock itself. From what I recall Crysis 3 is quite CPU demanding as well. So ridiculous as it might sound, but I think there may be demanding scenes in Crysis 3 which the 2500K at 4.40GHz would bottleneck the 290, unless you force ridiculously high graphic settings on the 290?

This ^^^ Possibly, In Campaign i get 0 Bottleneck from my P-II x6, i can't even remember if it does in MP.

I can give it a go to check that.
 
Thanks humbug, enabled overclocking in CCC and the afterburner overclock is perfect, holding 1098-1100 solid at a 1100 clock... So much nicer!

Top chap!
 
It would seem that even with the fastest CPU, there will be dips down to the 35-40fps range at certain scenes in Crysis 3:

It's probably scenes like that which the CPU only manage those frame rate but the 290 itself can manage 50-60fps or higher, thus the downclocking I guess.

So for Crysis 3, you probably would have to look at overclocking your i5 2500K higher.

Links in my sig, report it as a bug. Link to this thread in the bug report.

Have you set 2d/3d profiles?

It's not that. That is no longer required on GCN1.1.


Worth trying this above.

The solution i offer is below in the meantime.

Try this for a fix for the clock dropping. No need to use unofficial overclocking method either so clocks will drop to 2d levels as normal.

1. Download RadeoPro - http://www.radeonpro.info/2013/11/new-build-with-support-for-amd-radeon-r-series/

2. Create a profile using the game exe.

3. Click the profile tab, then the overdrive tab. Click the padlock to unlock overdrive, click enable graphics overdrive, the click 'always use highest performance clocks while gaming'. Don't forget to set +50% power tune in RP. Apply clocks and voltage settings through afterburner first. Now right click the game profile shortcut on the left and select apply then launch the game.

Thats a little odd, i don't remember FPS dipping anywhere near that low there, not even with everything on Very High.

The most demanding part i found was The Rout Of All Evil, it gets low 30's to low 40's and thats completyely GPU bound on all Very High + 4x MSAA.

May have spoken too soon :-(

It seems better but it's still fluctuating.. I've tried the RadeonPro application. It seems to be holding the maximum overclock most of the time, but it will suddenly dip to say 800mhz for a few seconds causing low FPS then spring back to the overclocked speed. It makes the game somewhat unenjoyable to play given it's really smooth one moment and noticeably into the low 30FPS the next. It doesn't seem to matter which GFX settings I use, even on low settings it delivers the same varied clock speeds.

I am loosing faith in AMD pretty quickly, kinda wishing I hadn't *wasted* the money on this card
 
Single player
I still think it could be CPU bottleneck to be honest...looking at the particular screenshot, I think it could be the game physics hammering the CPU's performance may be (with the rain etc)? And there's quite a lot of objects rendered in that scene as well.

Try enable CPU monitor and check CPU usage at that scene as well may be?

These GPU's do downclock if they are not full utilised, be its vSync or a CPU bottleneck they will only run at the speed they need to to keep the performance up.

Its a power saving feature.

What level? i will turn my setting down to off load onto the CPU.
 
I started the game on the first level from the beginning. It was the first inside event when you cloak. The clock speed is quite sporadic.

I just used RadeonPro on Tomb Raider with everything at maximum graphical settings and it held a solid 1100mhz and 60fps when playing for around 15 minutes. I don't know if it's a bug with Crysis 3, or maybe I am hampered by my CPU as mentioned by Marine. But I don't recall this being an issue on pre 14.* drivers.

I'm really tempted to get Titan Fall, but I am worried about it running properly with these AMD drivers. I am half contemplating a PS4 in all honesty, as I had a quick blast on one a month or so back and the quality and frame rate looked identical to my rig without the worry of compatibility issues. Only trouble is those pesky controllers.
