Ratchet and Clank LOD errors and lag spikes

[GoogleCodeExporter]

Been having issues with the Ratchet and Clank series, the Level of Detail seems 
to be corrupt and causing massive lag spikes due to the glitchy textures.  It's 
clearly a Level of Detail issue as when viewed up close the textures can be 
viewed as normal but when further away they distort, the further away the worse 
the distortion effect.  I'm guessing that it's a mip issue with the loading of 
lower resolution textures of a higher resolution image.

When you launch the game all seems to work fine, no lag or distorted textures 
but the second the game attempts to render anything but cutscenes it starts 
having massive distortions and performance drops.  If I'm correct about it 
being a LOD problem than that explains why cutscenes don't have the issue 
because they always display the highest resolution textures.

The PCSX2 log doesn't show any errors in itself despite the obvious graphical 
and performance errors occurring in game.  

I use PCSX2 1.0.0.r5350 with Windows 8.  No plugins.

My computer operates using an i7-3630QM CPU, a Geforce GTX 675mx GPU with 4 GB 
GDDR5 and 16GB of 1600Mhz dual channel RAM.

This is a known hardware rendering limitation (software mode fixes it).
The slowness is from the game engine trying to render too fast and you can help
it by working with the cycle speedhacks a bit.

How do I enable 'Software Mode' and cycle speedhacks?
