The only games I have on hand right now are SMK, SMG2 and Skyward Sword; all particularly demanding but performance-wise I saw little improvement after upgrading from a 3570k @ stock and gtx670. My current specs as well as my default settings are in my sig and I should note that by default my settings are optimised for quality and compatibility. If a game has performance issues, after trying both backends, I tweak the following until I hit max fps unless the game requires it:
Skip EFB access
Ignore format changes
EFB to Texture / cached RAM
Texture cache to fast
XFB disabled
Fast depth calculation
Disable per-pixel lighting
If that's not enough I switch audio to HLE, then gradually reduce AA and as a last resort reduce IR.
For all 3 games all the above had to be applied; with SMG2 and SS @ 3xIR, and SMK @ a stomach churning (not really all that bad
) 2.5x to avoid constant drops. This wouldn't bother me so much but this is exactly the performance per setting I remember under my old hardware. If anyone can give me an answer I'd apreciate it, thanks
