Help with GoDFollow

I bought GoD in hopes of helping lvl through the nightmarish mid-50's and i have found that whenever i go to Naderia's landing or anything to do with GoD my graphix go right downt the pooper. The clipping doesn't work (i think thats what it is called), i can see right through buildings and floors and when i try to zone out , the game crashes. It has to be GoD because it only started happening when installed the game. I have:
733mhz comp
513 mg ram
NVidia GeForce4 Ti 4200 graphix card

any help would greatly be appreciated. Thank You!

Naderia's landing is arguably one of the most graphics intense zones in the entire game. Try enabling texture cacheing and disabling all the graphics models and see if that helps.

Do you have the 64mb version of the 4200 or the 128mb? those 64mb cards are really underrammed and do not perform well in there at all
