The low res textures is a known issue, at least for a lot of PS3 gamers. Don't know if Bethesda acknowledged it yet though and if the upcoming patch will fix it. From my experience it isn't related to the lag, because most of my textures didn't stream properly since day 1, yet now, as my save file grows close to 10mb, more and more textures seem to be working alright while on the other hand the lag increases significantly. It's a case of bad vs. terrible and there isn't much you can do about it other than waiting, hoping, praying.
They said that the pathc that will be released will fix the problems that ruined the game's experience on console. Now, the two consoles are Xbox360 and PS3. If Bethesda assured that -all- the issues of the games will be fixed, I suppose that the worked on fixing the texture streaming issue too? Since It's one of the main problem of gamers. Even If It started appearing on Xbox (that's stupid, just because there are more Xbox players than PS3 players that compaint about this I would find it ABSURD If the texture patch is adressed ONLY to the Xbox version of Skyrim, especially If they already know that on PS3 the texture streaming is a problem MANY complaint about) that doesn't mean that on PS3 that issue doesn't exist. I feel very disappointed to see such a wonderfrul game almost destroyed by the low texture resolution. It's not worth it. The Elder Scrolls is without a doubt one of the BEST RPG ever created. We can't let a few stupid bugs ruin it. So, i keep hoping wityh all myself that Bethesda team was intelligent enough to udnerstand that PS3 version of Skyrim needs to be fixed about that problem too. I still dont know If It's due to the lag, but I don't think so. I played at Skyrim and there wasn't any trace of lag, but many texture didn't load and everything was awful...Many clothes, rocks or trees are horrible. So do you think that the patch will include the fixing to this problem too? After all, many articles talked about that saying that on PS3 the patch would have fixed this. But after a few days, the "texture streaming issue" became a "lag issue" (while the texture issue kept and keeps being complaint by many gamers). I just hope they didn't forget that PS3 version needs to be fixed about this too.
