Emulator Issues #2811
Wii Sport Resort Tennis Table - framerate drop
What steps will reproduce the problem?
1.Run Wii Sport resort
2.Select Tennis table game(Ping Pong)
What is the expected output?
What do you see instead?
When the ball was hit by the player the FPS strangely drop down to <30
When the AI hit the ball the FPS return to normal >50 (in my system.)
It looks like a CPU bottle neck during AI calculation, but half of the fps seems to much. IMHO
Dolphin version with the problem? Other Dolphin version without the
Every version, also newest.
32-bit or 64-bit and any other build parameters?
OS version and versions of tools/libraries used?
Please provide any additional information below.

Further testing with recent version.
If you disable frame limiter, you can see the fps drom from 130% to around 70% speed as soon the player hit the ball. The fps again pop up top 130% speed, as soon the CPU hit the ball.
It happens with any video back end, so it evidence some kind of bottle neck somewhere in the CPU emulation. Hope to help.

I tested this pretty thoroughly, and it appears to be something to do with the Wiimote rumbling. Alternate Wiimote timings doesn't help it, and playing on multiplayer causes it to happen on both players shots, and the slowdown ends at the same time as the rumbling.
When the AI hits the ball, it doesn't slowdown, only when a player, and only for as long as the Wiimote is rumbling.

Okay, I jumped the gun a bit on my previous conclusion, it's not rumbling, I turned off that in game option, and the frame rate is a LITTLE sporadic in multiplayer, although not as bad as single player. I'm going to guess it's a mixture of the splitscreen, calculating where to move the players, and in single player, the AI itself. But it's not abnormally slow, considering how the game runs. I don't see the issue.
