Direct3D 11 Slow Performance in Sonic Colors

[sashavol]

Title mostly describes my issue with Sonic Colors

Under Direct3D 11:

Code:

2x native (1280x1056)
AA: 8 samples (quality level 16)
AF: 16x
Scaled EFB Copy
~all other settings stock

gets around 12 fps in Sonic Colors at the act selection

Under Direct3D 9:

Code:

2x native(1280x1056)
AA: 9x SSAA
AF: 16x
Scaled EFB Copy
~all other settings stock

gets a solid 30 FPS on act selection and remains at VPS/2 if FPS limiter disabled

With OpenGL the act selection screen runs faster than Direct3D 11 at 4x native with all max settings. (Won't even post specs for that, there's something wrong there)

This issue does not seem to occur in Super Mario Sunshine, as far as I have seen.

Catalyst 12.8 (Latest)
Gaming settings default
MSI Afterburner controlling the overclocking on my HD 6950. There are no FPS limits in place.

Even at the WII notice that happens at the launch of the game I get around 30 FPS (out of 60). This should be the least demanding part of this game.

Are there any settings that would optimize the performance of Direct3D 11 in this game, or should I just stick to D3D9? There is obviously no difference, but it may be good to know regardless.


Computer Hardware:
PowerColor HD 6950 2GB @ 915/1350
Corsair Vengeance 8GB(4GBx2) @ 1600MHz
Intel i5-3570k @ 4.3 ghz

You have a good graphics card but try lowering some of the enhancers like AA and see what happens, different games use different amount of resources so even if it works well with SMS it dosent guarantee SC will be the same.

Altho the kind of AA that dx11 should be less demanding I belive
