all you have to do is use the console and enter in the proper command lines to change race/birthsign..etc, you can do it at any point in game...the command list is on any cheat site.
my thoughts about this game is that it has more detail foot per foot than any game ever made, to see such a large landmass where all objects in game have high polygons and detailed textures is very refreshing, most free roam games have both detailed objects and very ugly objects, they definitly spent alot of time on each thing and where its placed.
if anyone has high pc specs, i got the textures to look unbelievable even up close or at angles using the following nvidia driver tweaks:
84.25 beta (optimized driver specifically for oblivion)
forced AA/AF to 16x
image - high quality
trilinear opimization- off
anisotripic mip filter- off
anisotropic sample optimization- off
gamma correct aliasing - on
transparancey aliasing - super sampling
negative lod bias - allow, only if using high AA
render frames ahead - 0 ...experiment with 2 or 1 first..this tells how many frames it will hold in advance of being displayed, for this game in particular, using 2,1,0 can help free mouse lag or prevent freezing.
