EA-014 [4541000e]

Bug Description

Framerate sticks at around 5-10 FPS throughout the game at rendering scale 1x (drops even further at higher scales).

Steps to riproduce the issue:

1. Open Xemu Emulator
2. Load the game
3. Reset emulator
4. Let the game load to Main Menu (or skip intro video)
5. Press "New Game" and select any save slot
6. After the loading screen, the intro cutscene plays at a sluggish pace

Expected Behavior

Despite gameplay was not flawless before, the game ran at an average of 30 FPS with peaks at 60 FPS.

It seems fixed from my testing as well.

Tested it again recently the frames are a little too low

This happened in the most recent version which is v0.7.58 and the previous version v0.7.42

[vawtg]

I tested all versions of xemu recently this Month, I started from version 6.2 since the game was fixed in that version, from version 6.2 to 7.8 the game was working fine at a average 60 fps and 6-10 mspf, the performance went down after version 7.9, the performance regression continued from version 7.9 to version 7.66 which is the current version. The game ran at the range of 15-30 fps with some peaks at 40-41-42, the frames bounce around a bit depending on the resources of the game, some versions had a peak of just 40 fps, I have attached a screenshot where you can see how I was able to get peak fps.

The save I used to test was bourgin and borkes level, moving around the game worked at around 15-30 above fps depending on the resources, I stood in a corner where resources are a little low was that way I was able to conclude with the peak fps.

The only version which was a exception 7.63, the game become unplayable.

the performance is fine from version 6.2 to 7.8

7,9 was where the performance regression started @deepdive93

anyone managed to find a fix for low FPS?

[ehw]

I can't seem to reproduce on my end. Performance in the initial few seconds of the opening cutscene drops to around 40-50fps, but then the rest of the game seems smooth.

From my side, I just tested with Xemu Version 0.7.85, nothing had changed.
@ehw could you test this game Xemu with a AMD GPU? Under Linux?
