Install Oblivion, then the patch (or the Shivering Isles retail expansion disc, which has the same effect - but I’m assuming you don’t want to wrestle with Shivering Isles compatibility problems here), and then the Unofficial Oblivion Patch with the QTP3 UOP350 Compatibility Patch.Ģ. You’re going to need about 15Gb of space on your hard-drive. I’m also paying special attention to enhancing the eye-candy in the outdoors environment in strict keeping with Bethesda’s original vision. There’s very little wrestling with compatibility issues here, or with fiendishly complex installs that require cleaning/combining mods - but my tutorial still manages to get you to a point where most of the main/core issues in a plain vanilla retail Oblivion have been dealt with.
