For some reason pcsx2 caps the frames of my NTSC iso of Front Mission 4 to 50fps. No matter what I change, speedhack, renderer, sw/hw mode, plugin or otherwise, in many screens the framerate is just capped to 50.
The only way to change it is to uncap the frames altogether (F4) which results in 70+ frames which is altohether too fast again.
The frustrating thing is that my pc can keep up while juggling 5 basketballs and and peeling 20 kilos of potatoes EE/GS/VU under 50%.
Check the screenie....it's kinda sad.
Anyway, does anyone know why this is or have have the same issue?
Short specs:
Windows 7
PCSX2 r5350
Gsdx32 r5334 (sse4)
DX11 plugin
And no matter which NTSC Bios I use (I have tried all 4). It boots fine at 60fps, as it should for NTSC and then as soon as I load my game it drops to 50fps cap.
When I am in a fight or at certain cutscenes it temporarily increases again to 60fps. Its just inconsistent and I'm stumped to remedy it by myself.
Judging by the behavior of the music and voices I don't think so. They have a definite "slow-mo" sound to them...
Example:
- When browsing weapon parts it's 60fp[s
- As soon as I leave that screen is slumps back to 50fps
The change in music tempo is just too odd to be intended.
Maybe it's a side-effect of some "special use" of the ps2 engine that causes the emulator to interpret the instructions as such?
While it's definitely not a game-breaker I do think it merits further investigation. I'm ready to help in any way I can...non-decompiler stuff that is.
This is a clean un-cracked/patched iso. I guess the crc would have failed if it wasn't. It shouldn't matter whether I rip with daemontools or alcohol, right? I've ripped my entire collection as such without problems so far.
In any case, it's doesn't seem to be a settings issue, as I had naively hoped. I'll just play through as it is. Perhaps I'll make a real bug report but I doubt it will get a high priority.
Sounds a bit like the frame cap issue in that Street Fighter game. Basically this is a combination of VSync and weird update rate.
Try to force VSync off everywhere you can (also disable Windows Aero by using a "basic design").
