AMD Catalyst 13.8 BETA (13.200.0.0 July 23)

What channel of Chrome are you using, and do you have any flags enabled?

 

I second that

 

Stable (latest), and no flags enabled, all default. I have tried re installing chrome many times over. When watching some Flash videos my Gpu spikes to 99% usage and stays there, turning off hardware acceleration fixes this. But it never used to do this, it's new. The drivers, Chrome, can't put my finger on the cause.

 

Snip

 

I have a similar issue with these drivers and Chrome, I get a GPU spike to 85% every 5 seconds or so... I couldn't figure out what was causing it, so reverted back to the previous beta and all is stable now.

 

What we want to know is when the second phase of the drivers coming out.

Most the games I play are Dx9 lol Fk u previous console generation...

 

It's good to know I'm not the only one. Countless search queries in Google throws up nothing related! I uninstalled the 13.8's via add remove, restarted the pc, reinstalled them again (express install), restarted, and now everything has gone back to normal. I think it's something to do with flash player too as my mums laptop, a Sony Vaio, running Ati dedicated (quite a few generations old), her Chrome freezes up too, just like mine did, the thing is she isn't running any 13 series drivers.

 

Are we getting WHQL for this driver or new beta soon?

 

Spoke too soon.

Haven't restarted the pc since it's been working but I've been browsing for a while and the Gpu is spiking again. It seems to spike when i've been to youtube or watched a flash video somewhere else, once those clocks kick in higher its Helter skelter until I restart.

Looking in the resource manager. gpucache - for chrome, came up as using the disk quite heavily.

I wonder if this has anything to do with this?

 

On Windows 7, Switchable Graphics menu appears fine with these drivers.

 

How come i don't see it? Switchable graphics menu and crossfire menu are missing for me...

If it's not W7 then must Llano APU where the problem is...

 

Not too sure; I did a fresh install of 7 SP1, and immediately installed the 13.8 Mobility beta just to check (no Windows Updates at all) and noticed that Switchable Graphics and PowerPlay sections looked and worked fine.

Decided to reinstall Win7 again to set it up the way I usually do; hopefully the drivers still work fine afterwards though

 

I installed these last week and the PC has run flawlessly with them.
Performance is about the same as the last drivers I used.

 

I have a single 7950 and I get a significant performance loss with 13.8.
I lose close to 2k in my graphics score in 3dmark 11 and fps tanks in arma 2.

i went back to 13.6 beta 2 and i get the performance back.
just my 2 cents.

13.6 beta 2 - http://www.3dmark.com/3dm11/7029498

 

Same here. I noticed that games like Planetside 2 and Crusader Kings II started stuttering heavily, mostly when rendering new scenes. In PS this meant turning around, and in CK2 it meant zooming in and then trying to scroll on the map.

Hopefully the next drivers give more love to the 7950.

 

Noob question, did you increase board power limit?

 

Yes, both OCs were identical with power limit set to +20%. The only difference was the driver.

 

I can confirm this. Definitely caused by 13.8.

 

How about other 7950er's experiences? Are others solo 7950 cards getting performance docked with 13.8?

 

Have not tried older drivers, but for the 7990 performance drops when I start overclocking on these. Also more severe stutter gets introduced, the more i clock.

Running on default clock is almost perfect even with lower framerates ( less than 40).

Using Crysis 3 for testing.
