The tweakguides link is very informative and a great read, thanks bben46 :) I must say that I used Nvidia control panel last night searched for Oblivion.exe and started to put everything on max to stress my system and see what it looked like. Wow pleasantly surprised now the game looks amazing with HDR and full anti aliasing set to max, and it didn't really seem to affect my perfofmance on FPS. If you have a Nvidia card I suggest you tweak around with the control panel settings, I also did this with Half Life 2 and now it looks tremendous... Praise Nvidia :)
