State: closed
Merged: Yes


Seems like this is valid behavior on hardware. I'm not aware of any retail games that need this, only homebrew (e.g. ps1-tests).

There's a slight performance hit on this -- On the FF7 opening movie I'm seeing maybe 1 fps lost from uncapped fast forward at 300+ fps on a ReleaseLTCG build and approximately 0.5 fps lost from uncapped fast forward at ~63 fps on a DebugFast build.
