I don't like to be the one to tell someone this but you need a better graphics card. You've got your settings maxxed out and the game is doing what it can to get you a great view but your video card is letting it down.

Hm, then it must be something deeper. I have a 5770xFire set up and play games like Skyrim, Arkham City, Witcher 2, and Borderlands 2 on max if not ALMOST max settings. I was reading some stuff about needing to roll back drivers, but I assure you it's not that I need a better card for a game released 10 years ago!
If you feel the need to point out what we all already know, that RCT3 was released "10 years ago" then I have no idea why you'd need help with this issue or why you are still involved with the game. If you’re that concerned with how old RCT3 is then you should have uninstalled it and thrown the RCT3 disk in the trash about 8 years ago. However you've asked for help, have gotten it and have now informed our members that you’ve decided the problem is not with your graphics card and that RCT3 is an old game anyway.
In view of this, what you need to do is ask your question on the new game sites, the Skyrim forums, the Arkham City forums, the Witcher 2 forums, the Borderlands 2 forums and the 5770xFire forums. Ask those members how they get their set-ups to work so well and hopefully someone there can tell you what you want to hear. I've never heard of those games, nobody I know plays them and I am not signed up on those forums so I can’t tell you where to find them.
Good luck.
