Tried it recently, but not only is it slow in places, the texture work doesn't seem to work properly either, don't know what I'm doing wrong. Tried Okami, and GoW.
GoW is one of the games it has problems with I think. I haven't tried it myself, but I've read some posts on the official forums saying that it doesn't display correctly.
It's worth noting that the version on the main website (0.9.6) is actually pretty ancient now. It's much better to grab the latest one from here
, which includes newer versions of the emulator and the plugins it uses. There are a lot of new speedhacks and such in the newer versions which really boost performance.
Make sure to use the GSDX10 graphics plugin too if you can. I think it's set to use the ZeroGS plugin by default, which isn't nearly as good in my experience.
