Description
Summary
On the Mupen64Plus core with the GLideN64 video plugin there are graphical glitches as well as slowdown when there are many characters on the screen. Despite the game running slower the FPS remains at 60. Switching to Glide64mk2 fixes the graphical issues but not the slowdown. When downloading Mupen64Plus on it's own and running the game on it these issues didn't appear.
Repro
- Open Harvest Moon 64 (USA)
- Graphical issues will appear at the starting logo
- Wait for the intro cutscene to play
- There will be significant slowdown during this cutscene
Host env.
BizHawk 2.7, 2.8, and 9bc16466; Win10 Home 21H2; NVIDIA GeForce RTX 2080 SUPER

Research direction
No source file, test, or entry point is named. First reproduce Harvest Moon 64 (USA) on the Mupen64Plus core with GLideN64, then compare the starting logo and intro cutscene against Glide64mk2 and standalone Mupen64Plus. Done means the graphical glitches and cutscene slowdown are resolved without changing the reported 60 FPS behavior.
