Apparently it reduces the load on the CPU, has anybody here had any increase in your framerates since updating?
Nothing that noticeable; OGL still crashes.
Are you coming from the last WHQL driver release? Otherwise I'm pretty sure the directx increase they are talking about was already introduced with 337.50, their last beta driver.
337.88 uses application profiles to optimize specific titles, will have no effect on Dolphin, it may have an effect if you rename "Dolphin.exe" into watchdog.exe ( or whatever the name of the exe is)
Just to say the obvious, the above is a horrible idea, don't do that.
