GTA IV Problems? Glitches?

Well, Nvidia and ATI has released Beta drivers for GTA to run a BIT and I do mean a BIT better. FPS and some textures if were missing will show but for everyone who doubted the minium specs, boy...Time to ask Santa for a new computer. I tried to run it on my computer...Hah...With a Nvidia Geforce 6200 A-LE, and wow. First, loading took some time. Second, the intro at beginning...Heh, the ship was missing. All I saw was Niko and his friend. Third, when I skipped the intro and the long loading screen, the car...the car had no detail what so ever. The ground...I can't even describe this. Just warning what happens if you don't have the minimum/recommended specs. But I'm not sure if the miniumum or recommended specs could run it. Quad core for a game. That's a laugh. The patches and drivers should be on GTAIV's site. If not...You know who to trust, Google!
