I haven't played Oblivion for a few weeks, but today i decided to pick it up. Once i loaded the game the graphics became all fuzzy and ill-defined. I'm running a single 8800GTS. I've tried my other games, supcom and Crysis to name a few and they all work fine. I have made absolutely no changes to my system since I last played Oblivion and it worked fine then. I'm running Windows 7 Ultimate x64.
Sorry, you misunderstood me. The graphics are about as bad as a really really old crt tv. It's not just the game, for some reason the graphics have gotten worse. And yes i have gotten qarls texture pack, but i haven't forced AA or AF... I'll go try that
I was actually having the same problems when I installed my new hd 5770. I did a few things and it works perfectly now w/ quarl's texture pack installed. First, try deleting your oblivion.ini file in Documents/My Games/Oblivion. This will make the game create a new .ini file. Next, when the launch screen comes up, click options. It might say that it will now detect the best settings based on your video hardware. For me, it was always choosing very low quality, even though I have a quad core processor, 3gb ram and an HD 5770. I had to select very high quality and then select the resolution from that screen as well.
That helped me, so hopefully it helps you as well. If you have any omods that affect the textures, such as quarl's, you might want to deactivate and then reactivate them as well.
