Vice City textures not loading quickly

[ShawnD1]

If I'm driving too fast, I'll start to get into areas where textures are not yet loaded and I end up crashing into invisible walls, invisible trees, and invisible hedges. If I'm riding a bike and pass by an ammunation, I'll turn around and enter the store to buy something but I have to wait like 10 seconds before the textures and that pink circle (where you stand to buy stuff) even load.

The option "Draw Distance" is set to the maximum in video options.

Is there any hack or mod or something I can get to fix this?

Here is my system:
Athlon 2500+
1GB ram
Radeon 9600xt
Sound Blaster Live 5.1
