FAQs help you to find and solve quickly your issue.
Why does my water disappear on swimming? This happens on NVIDIA cards using ENB/ENBoost. You have to disable the water displacements in your Oblivion.ini.
Why does my screen is sometimes grey or strange effects happen? It is the Steam overlay. You have to disable it.
Why does my OR menu is "blocky" style? This happens using ENB/ENBoost. You have to disable the speedhack of ENB/ENBoost.
Why does my Oblivion CTD on loading main menu? The installation procedure is not correct and you are probably not using DarnUI. Follow the install procedure faithfully.
Why does my Oblivion CTD on new game and during the gameplay? Unluckly Oblivion has a lot of CTD for several reasons. Anyway this can happen if you have the EquipmentMode and/or MountedCombat enabled. Try to disable it. The features are still in development.
Does OR's weather system conflict with All Natural or any other weather mod? No conflicts occur but it is possible the effect you obtain is not correct. I recommend to try OR's weather system without other weather mods.
