Horrible stuttering problems.

[willkuer]

so your GS% stays low but the framerate drops using ogl?
GS% stays at 1% even in s/w renderer?

[undeadgenesis]

I haven't seen any framerate drops. I can see spikes in the frametimes but it hasn't dropped below 60 fps yet. in software mode i saw it as high as 7% but it never stays there

[willkuer]

it is almost constantly 60 all the time and sometimes the fps increase?

[undeadgenesis]

that is what afterburner(constant 60fps) and the built in fps reader(59-61) say

[willkuer]

So you only hear the see stuttering? What happens if you use the async mode in the spu?

I would now say that tsunami was right. It sounds like unstable clock speeds. Have you tried disabling the framelimiter? Just to make your cpu struggle a bit.

[undeadgenesis]

The stutter is just in the backgrounds of the world(basically everything but the sprites). disabling the frame limiter actually stops the stuttering and the Frametime graph is a lot less erratic. I have speed step disabled so it running 4.3 constantly.

[willkuer]

Just to clarify: Disabling speedstep didn't help but disabling framelimiter does?

Then I would check power saving features of the gpu.. Probably this is downclocking as well maybe you can also check the gpu status using gpu-z during normal scenes and lags.

[undeadgenesis]

You would be correct.
The gpu clock is at 901 with a 2 percent load. power management is at prefer maximum performance.

[willkuer]

Then just set internal resolution to 4x or 6x until your gpu is busy enough or try to solve the problem in the gpu settings/driver/utility.

Edit:
Not to forget: use the h/w renderer

Edit2:
Assuming you have solved the problem and are having fun now playing the game - I go to bed. Good luck if there are still problems.

[undeadgenesis]

well i set the resolution to 8000x6000 core clock still 901 at 50% load. starting to think a windows reinstall might solve the problem
