same problem. did anyone figure out a fix for this?

I followed these instructions, replaced my detected shader (which was 13) to shader 19 and it's working.

 

bAllow30Shaders=0 - If set to 1, this option allows (but does not force) the use of Shader Model 3.0 on graphics cards which support it, namely Nvidia GeForce 6600 or newer, or ATI X1000 series or newer. This can potentially improve performance when using HDR rendering for example. Check yourRendererInfo.txt file in your \Documents and Settings\User\Documents\My Games\Oblivion directory to see if your card supports SM3.0 next to the option '3.0 Shaders'. Note however that even by enabling this option, Oblivion still appears to use 2.0 shaders (check the 'PSTarget' and 'VSTarget' lines in Rendererinfo.txt). In any case, if you have one of the cards mentioned above, it cannot hurt to enable this option.

 

Update: To force the actual use of 3.0 Shaders after making the above change, you will also need to check your RenderInfo.txt file (see above), and on the last line of the file check which shader package it uses (e.g. Shader Package : 13). Then go to the \Program Files\Bethesda Softworks\Oblivion\Data\Shaders\ folder and rename that particular package to something else (e.g. rename shaderpackage013.sdp toshaderpackage013._bak. Now copy shaderpackage019.sdp and paste it back into the same directory, and rename this new copy to the package name your card uses (e.g. rename it to shaderpackage013.sdp in this example). This will force Oblivion to use the Shader Model 3.0 shaders in the game, which may increase (or reduce) performance and typically shows no image quality difference.
