... 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...
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.

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.Edited by Offler - 4/4/14 at 4:41am
