TheLoafyOne Posted January 28, 2014 Share Posted January 28, 2014 I'm at my whits end trying to figure out this issue dealing with my sky in oblivion. With HDR off the sky appears to be black whether inside a city or outside a city. With HDR on the issue goes away but I can't use anti aliasing and forcing AA in Nvidia control panel doesn't seem to do anything Except for FXAA which actually causes more problems than fixes. I want to use the more up to date shader package, the game actually seems to run better with it on, and I want to use AA as well because Jaggies drive me crazy. Any help would be appreciated.

Striker879 Posted January 29, 2014 Share Posted January 29, 2014 I had something similar after my SLI rig died. I put in a replacement card I had kicking around and got black skies. Then I remembered I'd used the instructions in Koroush Ghazi's Oblivion Tweak Guide to force Shader Model 3.0 (which worked fine on my 8800GTS SLI). After a bit of investigating I saw that the 9800GT replacement would also support Shader Model 3.0 so I just needed to redo the steps for getting SM 3.0 to work. You'll find the instructions on page 8 of the guide (which I've quoted here): 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 your RendererInfo.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 to shaderpackage013._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. It was the RenderInfo.txt and rename steps I needed to redo. Backup your current in use shader package and try Koroush's instructions and see if it helps.

Lanceor Posted January 29, 2014 Share Posted January 29, 2014 You can force AA settings through an nVidia card with an application called nVidia Inspector. The important setting which makes it work is "antialiasing compatibility" which you need to set to 0x20410041. Link to comment Share on other sites More sharing options...
TheRomans Posted January 29, 2014 Share Posted January 29, 2014 Yeah when I forced shader pack 19, the sky would only work with HDR enabled. I dilike all the HDR shinyness, so I went back the shader 7. Link to comment Share on other sites More sharing options...
TheLoafyOne Posted January 29, 2014 Author Share Posted January 29, 2014 Doesn't seem to work depsite that hex code. Furthermore, I can live with shaderpackage 4 as long as I can figure out what causes massive FPS drops whenever I'm around any actor. For those who are curious I have a 2.66-2.67 Ghz Core 2 quad q9400 Skyrim runs flawlessly, for some odd reason oblivion kicks it's butt. Link to comment Share on other sites More sharing options...
Striker879 Posted January 30, 2014 Share Posted January 30, 2014 Here's a recent discussion on that problem: Low FPS on modern PC. Link to comment Share on other sites More sharing options...
TheLoafyOne Posted January 30, 2014 Author Share Posted January 30, 2014 I actually read this post not too long ago but it didn't seem to help my issues. Am I supposed to just live with the fact that my FPS is going to drop to 25 every time I enter a city or an over populated area? it's kind of maddening.

Striker879 Posted January 30, 2014 Share Posted January 30, 2014 That's not a bad frame rate if that's as low as it goes. This isn't an online first person shooter where the guy with the best FPS wins. Link to comment Share on other sites More sharing options...

This isn't an online first person shooter where the guy with the best FPS wins. I saw you mentioned that in one of the other posts. But the fact of the matter is I like having a steady framerate, when my game begins to fluctuate it makes my anal retentiveness go off crazily. I guess I'll just deal with it for now, but ehh..

TheLoafyOne Posted January 30, 2014 Author Share Posted January 30, 2014 well lanceor seems as I got the anti aliasing to work perfectly now, I had to make the X lowercase on that code and it dialed in just right. Link to comment Share on other sites More sharing options...
