This game used to run full speed in the dolphin 3.5 days but around the of 4.0 has turned into a slide show. Any plans to optimize this game back to the speed it was in 3.5?
3.5 was faster in some situations because of inaccuracy and bugs, not because it was optimized better. The developers will as usual continue to try to make Dolphin faster, but there's no guarantees about when you'll be able to run this at full speed.
Use the latest dev build?
This game is extremely slow, but making threads asking for it to be restored to speed is very useless. I'm closing this thread as there isn't much you can do beside bisect to when the performance changed, and you never bisect anyway.
