Frame skip interface issue.

[Nightquaker]

I know that CPU clock can be particularly effective with Pulse, but it wasn't in my case. Enabling timer hack also didn't work. The issue seems to be pretty well known, though, and might have something to do with texture caching, but I'm not sure.

Also, I don't think that in previous interface maximum frameskip was fixed to 1 as I had more than 1 frames skipped while using auto frameskip in really demanding games like Gundam VS Gundam Next Plus or God of War.
