Emulator Issues #11791
Castlevania III wrong framerate
Castlevania III: Dracula's curse, PAL
Game ID? (right click the game in the game list, Properties, Info tab)
MD5 Hash? (right click the game in the game list, Properties, Verify tab, Verify Integrity button)
What's the problem? Describe what went wrong.
The game will randomly drop to a framerate of 40-44FPS, this will stay this way until the framerate is unlocked and then locked again after which it will return to 50FPS. After around 30 second the framerate will drop again. If the framerate isn't unlocked, the game will stay at 40-45FPS for the whole game (or atleast for 10 min from testing). Tried with single core, LLE audio.
The game doesn't support 60FPS so I couldn't test that.
What steps will reproduce the problem?
Play the PAL version.
Is the issue present in the latest development version? For future reference, please also write down the version number of the latest development version.
Is the issue present in the latest stable version?
No, I had no issues with 5.0.
If the issue isn't present in the latest stable version, which is the first broken version? (You can find the first broken version by bisecting. Windows users can use the tool https://forums.dolphin-emu.org/Thread-green-notice-development-thread-unofficial-dolphin-bisection-tool-for-finding-broken-builds and anyone who is building Dolphin on their own can use git bisect.)
I currently don't have time to bisect. Will bisect later.
What are your PC specifications? (CPU, GPU, Operating System, more)

This game is actually somewhat demanding due to how it uses the texture cache. Is it possible you're just lagging due to vsync and unlocking the framerate disables vsync and allows it to recover? There's no enough information in this report for me to recommend or think of anything else.
