I run an ATI GPU as well and I found that the Catalyst/CCC was messing with my SH5 performance.

Make a fresh driver install but don/t install the CCC, just the driver. The 11.7 runs fine on my system.
Make sure you first uninstall your current driver properly.

Go here for intsructions on how to do it;

Make sure you choose the proper Article - Article GPU-33/Win7, Article GPU-1/Vista, Article GPU-2/XP

I run a 27" display + the d3d Antilag and haven't had any FPS losses. These are my d3d settings;
RenderAheadLimit=3
FPSlimit=38

And my Main Menu settings;



Turn the Vertical Sync on.

Runs brilliantly.
I suggest you try it.
