Debil Skute

After coming back from a crash there was a message saying that SL had changed my graphics settings. I thought I had reset everything correctly. However there are several textures that I had previously uploaded that do not look as high res as before. Many are now pixeled out and/or blurry. I have cleared my cache several times to no avail. I can't see anything in my settings that would correct this. Did I miss it somewhere?
