The areas (not all) that come after this location are more geometry heavy.

Set the aspect ratio to stretch, it'll get rid of the black lines.

I tried Colony 9, Sword Valley, and the Fallen Arm. Still got around the same FPS for both (34-41 FPS) and they both fluctuate the same. This is as far as I got.

Stretched doesn't look as good. Some things are a bit off like the arrow pointing towards your destination.

I'm seriously thinking I'm just being overly sensitive now. >_>

The speed for Xenoblade Chronicles is 25 fps for the PAL version or 30 fps for the NTSC version and the PAL patched version, if u got 34-41 fps u have enough power to run it at perfect speed.

Quote: Overclock memory bandwidth ?
I've never heard something like that

Memory bandwidth (in bytes per second) = (total memory bus bitwidth * memory bus transfer rate) (sometimes called effective memory clock) / 8

You can raise your video memory bus frequency (memory clock) which will raise your video memory bandwidth.

The OP is referring to stuttering that sometimes occurs with high graphics settings in dolphin even if your framerate remains high. I and many others have observed this but I don't think anybody knows for sure what is causing it. All we know is that having a faster GPU does alleviate the problem even if your framerate doesn't improve dramatically.

What are your exact graphics settings OP (including video backend)?

Yeah, this is exactly what I was looking for. I guess I didn't use the search function well enough.


I turn Cache Display List on and off to see if it has any effect, but it doesn't seem like it does.
I also do load custom textures, but on or off the stuttering occurs.

And on the topic of memory bandwidth, does increasing the memory shaders affect Dolphin more than the core and shader clocks? Or is this simply not how it works. Thank you everyone.

Things to do (these should not affect the issue):
-uncheck fast mipmaps
-uncheck disable per-pixel depth
-uncheck cache display lists
-uncheck skip access from efb

Things to try (one at a time so that you can pinpoint which one worked, if any):
-turn vsync on
-turn openMP texture decoder off
-turn openCL texture decoder on
-turn AF off (I really, REALLY doubt this will have any effect)
-change the backend to d3d11
-change the backend to openGL

If none of these work post your nvidia control panel settings for dolphin.exe

Memory shaders?

woops. memory clock. my bad, and I'll either edit this post or add another post later.

[NaturalViolence]

It should. Although we don't really have any data to substantiate that claim. Also some have claimed that they resolved the issue at hand by raising the core clock of their gpu. If that's true then that would seem to suggest that the issue is related to pixel fillrate, which would make sense because it scales with IR.

None of them worked.



I think this is what you're talking about. While I don't have a specific nvidia control panel setting for dolphin.exe, I'm assuming it's affected by the global settings in that case.

[NaturalViolence]

Yes. Those look perfectly normal to me. I guess you're stuck with 3x IR if you want to avoid the stuttering.

Yep. It's no problem playing at 3x IR. 4x IR has a subtle improvement, but I can live without it. Thanks for the help!
