Choppy slow down on some games only

[rlacombe]

Hi all, any help appreciated here.

I have installed and successfully run Dolphin 3.5-367 and have happily run the majority of my games so far.
But some of them are just too unplayable due to choppy sound and slow issues.
But even when choppy and slow, the stats are telling me I'm still at 50-60fps, and game speed at 95%.

Need For Speed 2: Hot Pursuit is a the worst of them - renders it completely unplayable.
Metal Gear Solid: Twin Snakes also does this a little - not as bad, but definitely there.
Resident Evil (the remake) seems fine until the first zombie appears and then it starts dragging.

I thought my PC spec would be good enough for most games to be honest - but it appears like CPU issue maybe?
Tried many suggestion from thsi forum on the actual Dolphin config settings but nothing seems to work.

My specs are:

Windows 8 64 bit
16gb RAM
Intel i7-2600k CPU @ 3.40 GHz 3.40HGz
Nvidia GeForce 450 graphics card

Any help appreciated as some games run blindingly smooth, even on full screen at highest resolution with enhancements on - others unplayable even on basic settings.

Thanks all
Ricardo Lacombe

Thanks for the reply. Done that - latest version running but making no difference.
As a side note, I just ran F-Zero GX and that has really choppy sound, but the game appears to be running fine at full speed and playable - just audio. Others run with choppy sound and lots of dealy. Some games (Super Monkey Ball 2, Def Jam: Fight for NY) work absolutely fine at fullscreen too.

You'll need to OC your CPU, f-zero is very demanding

This. Same thing for NFS: Hot Pursuit 2 and MGS. These are very demanding games too

If the game's not running at a solid 60vps/100% speed, you're gonna have choppy audio. This wasn't the case with HLE on stable 3.5 and earlier, but back then HLE was kinda horribly broken and would cause crashes and numerous issues on top of the missing instruments/sound effects and crackling and distortion issues.
