Description

Game Name?
Fzero GX

Game ID?
GFZE01

What's the problem? Describe what went wrong in few words.
When sync gpu option is enabled lower than normal fps are counted as 100% emulation speed for the emulator making the game run in slow motion.

What did you expect to happen instead?
Normal game speed when run at 100%

What steps will reproduce the problem?
[Don't assume we have ever played the game and know any level names. Be as
specific as possible.]
1.Start a new campaign.
2.On the first race watch a slow motion race start where 20 fps are reported as 100% speed by the emulator for a 60 fps game.
3.

Dolphin 3.5 and 3.5-367 are old versions of Dolphin that have
known issues and bugs, so don't report issues about them and test the
latest Dolphin version first.
Which versions of Dolphin did you test on?
Dolphin-x64-v40-3022
dolphin-4.0-2881-x64
dolphin-4.0-2883-x64
Dolphin-x64-v40-3232

Does using an older version of Dolphin solve your issue? If yes, which
versions of Dolphin used to work?
Yes dolphin-4.0-2881-x64

What are your PC specifications? (including, but not limited to: Operating
System, CPU and GPU)
Windows 7 64 bit, 2500k, 560 ti

I think we have to get rid of the 1600 cycles per draw call asap. I guess there is no way to query the rendered pixels, but we're fine to check for the amount of vertices.
