I've been looking on various mod sites for something that will make the walls, floors, et al look sharper. I am running the game with all settings maxed at 1920x1080 resolution and when in dungeons, Ayleid ruins, etc. The walls and floors all look sorta low quality up close. Wondered if there was some way to improve their look.

http://devnull.sweetdanger.net/obliviontextureoverhaul.html is a great resource.

Well, the method of making them look better is somewhat simple, but extremely time consuming in that finding and altering every "Wall Texture" would take forever

Were you to want to make the textures look better, you would want to open the textures in The Gimp, scale the images to 4x their original size (i.e. 2x the height and 2x the width), and run a Unsharpen Mask filer on them. That said you WOULD take a performance hit due to using quad-sized textures, and as I said it would take a really long time to do and be annoying to redistribute (which is why you'll notice I'm not volunteering to make them for you ), but it would serve its purpose.

Probably not going to help you up-close problem, but forcing anisotropic filtering in your graphics card settings will help the game look nicer too.

I played QTP3 for more than a year, put up with all the CTDs, pretended to play while fixing the game all the time, then...
... was fedup, uninstalled QTP3, played vanilla for few months.

Then, lo and behold I (re)discovered the very cool combo of Bomret's Normal Maps + Corepc's Vibrant textures.
These are a legion, change about everything in game, with Enhanced vegetation, natural habitat, Beaming Sunglare - brand new looks!
Try it, it's safe, no FPS loss at all, great looking.

I am a QTP3 fan, and I have to jump in and say that you should pick the texture combo that looks best to you. I am going for QTP3R + Ampolex's textures this next go around. My last setup just used ATP/AMP, but I miss QTP3's sewers and other dark interiors. Both QTP3 and ATP use larger textures, however, so its up to you...

Thanks for the link. And all the other responses. Most suggestions made were on this website with screenshots and information. Looks like the QTP3 has what I'm looking for in improving the general look of walls and the environment. Since my graphics card has 1 Gb of memory, I shouldn't have any problems running those upgrades.

I'd definitely go with the redimized version, it is less intensive on the system and the visual quality is the same.

CTDs caused by what? Overloading your VRAM?

Arthmoor, my friend, at that stage of my personal development as mod user I had no idea what VRAM is
However, after a lot of CTDs I just reinstalled and... you know, Bethesda's work is unappreciated IMO. They've done pretty good job. Bomret and Corepc give it further boost.
Since I stepped down from QTP I can play 4-5 hours without a single CTDs, sometimes 3-4 days even.
I am sure my clumsiness can explain most of my CTDs but hardly all of them.
Now, with Bomret+Corepc I enjoy good looking game and play

VRAM = Video memory. The display memory on your video card. The less you have, the more susceptible you are to crashes relating to running out of it. It's why the general advice is to use QTP3-Redimized instead of the full version. Most people have either 512MB or 1GB.

Is there a guide to install QTP3-Redimized via BAIN?

I tried installing QTP3R with OBMM, but it always had a memory overload issue while building the OMOD, and would freeze...

Another nod for Bomret's Normal Maps. I like them a lot. Not too harsh like some texture mods (like QTP), where everything appears over-sharpened and, to me, unrealistic.

What is it that makes Oblivion's textures look so awfully blocky up close?

There was a very good texture mod released recently called Oblivion texture sharpening or something similar. I was amazed when I tried it as it does a very good job of making textures sharper. In fact, I think it is better than QTP3 redim which I was using. The main problem is it is more limited than Qarl because it doesn't alter all textures. In any area there are some surfaces that have not been improved. I think it is also more pc friendly than Qarl and causes less slowdown. I definitely prefer it to Qarl and Vibrant mods. It's availlable at TESNexus.

There are not special instructions for BAIN as QTP3 is a simple package. Convert it to an archive in OBMM (right-click on the OMOD) and install it with BAIN.
