I really didnt want to post this, Im really, really sorry for being "that guy" the one who interupts progressive, important on topic discussion that will advance these works of art further onto even more outstandingly beautiful territories. I wanted to find someone else whom has experienced the same porblem and solved it, then copy them. I do not usually ask for help, I try and solve things, and I have nearly always solved the problems I have encountered, BUT!
Really wouldn't worry about it. Stuff happens. But that's from another user, not one of the OBGE team, and I certainly won't try and claim I'm speaking for them. But I suspect they'd probably see it similarly, at worst. Anyway...
It was said that the problems with ATI cards has been sorted, so if anyone can shed any light on this problem I will be forever grateful.
DIdn't even know there was one. And I'm using a 5870 myself, fwiw.
All I have in my shaderlist.txt is Godrays.fx followed by pressing "Enter". The other effects, I enable, or not, via the in-game options menu. Mind you, I don't currently use DoF, so perhaps that would also need to go in shaderlist.txt; I don't know.
I did copy v4 of Godrays over the original. I haven't named it godrays43 or the like. Just godrays.fx still.
Full disclosure: I am using only SSAO_test with default settings and a few minor tweaks in ColorEffects, from the in-game menu. Other than that, it's mods, Oblivion.ini tweaks, and Godrays sitting by itself in shaderlist.txt. That's my setup. Oh, and with AA+AF forced via CCC, but I'm not entirely sure that's working as it should be. Oh well.
