I can tell you, because we have very similiar issues with Niberius. Most of DX games terrible stutter, This is most apparent with dynamic camera movement in games like Skyrim, Bioshock, Sleeping Dogs and Mass Effect. For me personally, only game that is not stutter is NFS Rivals and of course Mantle games (but Thief in DirectX mode stutter too).

Hello everyone,

I just wanted to chime in here for a second to assure you that I'm keeping a close eye on this thread, and let you know I've received lots of PM from you (which I always welcome wink.gif) and working with my team on the various issues you've reported.

What about a confirmation/hint regarding the GCN 1.0 Mantle optimizations coming in the next driver?

Hi SlackerITGuy,

I honestly can confirm or provide you any hints at the moment, I will get in trouble as I'm under NDA. I hope you understand.

I do.

That's okey mate, thanks for being so active here at OCN.

Exactly.

sincerely not found significant difference in GPU behavior...
at stock it drops the GPU core frequency in high performance mode and you have to overclock to fix the clocks, the performance in DX doesn't seem so better...
then, forgot to say that regardless of the driver version, the GPU load is really fluctuating... i don't think that's normal
to me this is a teething driver related issue, hope they improve with the next version
but they should do better to listen to their customers...
so, summarizing:
powerplay (auto and manual), fix the fluctuating gpu load and frame drops...

p.s.: e.g. this is Batman AO
VSYNC OFF -> VSYNC ON

other games have the same behavior...

Just a question... Triple buffering was on? I guess it was off.

Edit:
To Niberius: http://www.overclock.net/t/1450481/guide-advanced-fps-managing-lets-solve-stutter

For example Skyrim has Vsync by default always on. In that case, if the scene is not complicated to render and both backbuffer and frontbuffer are full the GPU has nothing to do = so it clocks down.

Then buffers flip, GPU start to work again but for a while its running on low speed.

There is one workaround = play game in Windowed mode.
DWM (on Windows 7 or Vista) has to store the data generated by game engine in backbuffer of its own. Effectively you have 3 buffers and stutter is solved.


Its a paradox, but the stutter is in this case caused by quick and smooth work of GPU and the way it tries to spare some electricity.

No, it's not. I always play with VSync, triplebuffering and frames limited to 60, so i'm used to things being smooth as butter, as everything, that could cause stutter is not relevant with my settings, nor did any stutter occur with any driver up to the 14.x series.
This clearly is a 100% driver issue.

I have no such issues of stutter with skyrim and a plethora of other DX games under any driver before the mantle releases. 13.12 is silky smooth, its a problem that wasnt introduced until the mantle drivers came out. Bioshock series is one that is now a stutter fest as well while remaining smooth under 13.12.
