Deviance No-Cd Graphics Problems

[secondpost]

I have Deviance No-Cds for GTA Vice City and Jedi Academy. In VC the graphics load really slow e.g. If I drive up to an Ammo Nation store the inside takes about 6 seconds to draw. In JA there are purpilish/pink shimmering textures in various parts of the levels. These issues aren't present in the games when run of the original cd's. Is this due to the patches or is it something that has to be endured when using no-cds??

Thanks.
