I'd like to know. I know they are trying to make improvements but I guess things have to go down before they can go up. I feel like every revision I try has some issue with certain problem games.
For Xenoblade on revision 3.5-367 Dolphin;
Open up Dolphin > Right Click on ''Xenoblade Chronicles'' > Properties> TICK ''Enable Dual Core'' and '' Enable Idle Skipping'' > TICK OFF ''Skip DCBZ clearing'' and ''Accurate Vbeam emulation''. Leave the rest on default setting.
Config;
General;
Basic Settings: Make sure both ''Enable Dual Core'' and ''Enable Idle Skipping'' are both TICKED.
Framelimit: 30fps and TICK ''Limit by FPS''
Advanced Setting: JIT Recompiler
Audio;
DSP Emulator Engine: DSP HLE emulation (fast)
TICK ''DSP LLE Thread''
Graphics;
Backend: ''Direct3D11''
(my adaptor is NVIDIA GeForce GTX 670 so keep that in mind)
Fullscreen Resolution: Mine is on 1920x1080 (reminder, if by the end of this configuration your computer can't handle it, bring down the resolution and see if there will be any changes if there are FPS issues.)
Aspect Ratio: Force 16:9
V-Sync: OFF
Use Fullscreen: OFF (optional)
Enhancements;
Internal Resolution: 4x Native ( makes a huge difference on Xenoblade especially if you have a 20inch monitor or above)
Anti-Aliasing: NONE
Antisotrophic Filtering: 4x
Scaled EFB Copy TICKED
The rest of the boxes UNTICK (blank)
Hacks;
EFB Copies: Texture
Texture Cache: Fast (max)
Other;
TICK ''OpenMP Texture Decoder''
Leave the rest of the boxes UNTICK
Please post if this worked for you. Best of luck. I'll post Metroid Prime config if the Xenoblade worked for you.
EDIT: The game should work between 29-30fps with no sound issues in battle or not. Rarely the sound issues will occur where the sound stutters. Simply change the time to day or night to change the music. This rarely happens, it happened after I tried to make gems, changed weapons, upgraded my skills and looked at the ''Friendship'' stars of people and companion then went back to controlling my character. Even then the stuttering only happened to my right headphone.
Post your results and tell me if there are any issues.
