For those who run Unreal in D3D and hate the dull looks, especially skyboxes...

    Check this thread.

    Credits go to Thesto Neroses btw.

    Apparently if you go to rendering (by typing preferences at the console) and set "usemultitexture" to false, you'll get rid of for starters those horrible skyboxes.

    Example:

    First shot: D3D, usemultitexture set to true

    Second shot: D3D, usemultitexture set to false :O)

    Check the skyboxes in Nyleve, Dark arena, Harobed, Trench, Vandora...

    Screenshots: Noork. Just in case...

    WARNING: Multitexturing is a a feature that allows graphics cards to add multiple textures to a 3D surface at the same time. This can double the performance (or quadriple) in multitextured games like Unreal.

    When you disable it, you get a big performance penalty because twice the number of clock cycles (or even more) are needed to render the same object. The penalty depends on the number of texture / effect layers are used. In unreal, double layer is common (texture and light/shadow maps) but 3 or 4 layers are also possible when detail texturing is enabled.

    MultiTexturing ON

    MultiTexturing OFF

    MultiTexturing OFF + Force multitexturing in OpenGL (nVHardpage setting)

    Conclusion: Disabling multitexturing does not show the expected performance drop. Possibly nVidia forces using multitexturing at driver level.

    Edit: tnx for posting that info Hyper.

    I run unreal on a gf2 mx btw. Dark arena looks just plain horrible in d3d with mt enabled. Just, when I compare it to mt disabled..

    edit: arg.. misread hyper's post.

    actually iirc the Unreal Engine flattens all multitexture textures before they ever get to the screen (if multitexture is off).

    Even if I'm wrong, it makes sense that having them off gives you better frames, because the video card doesn't have to render two/three textures at once, which frees it up for the other textures on the screen.
