Hey,
The best way to play Goldeneye is to use Rice 5.9.9 (6.1.1 is buggy for me, at least on my Radeon card) and when u enter a level turn on the frame skipping option in Rice's plugin settings. Use this combined with 1964's built in frame skip option and the game runs very well! However, make sure u turn the frame skip option off in Rice's plugin when ur using the ingame menus or they won't display properly. Let me know how u get on, this tweak worked wonders even on my old 1.4ghz Athlon rig
Another thing u can do if ur stuck for speed, is to download hackuruk(sp?)/azimers RSP plugin and use it in conjunction with schibo's 1.2 audioplugin aswell - this gives better performance, particularly on systems with lowend CPUs.
Hope it helps dude!
