OK - I tested the two versions a bit lastnight.
I havent ridden a horse yet, but the same building/structure pop-up still exists in the X360 version. You will be walking, slightly have the game slowdown and suddenly see a tower/building pop-up in the near distance....
Looking back on this some things I do like about the X360 version...
- The darkness is actually dark and very atmospheric...you NEED to use torches in the first dungeon/sewer level and the deepness of the atmosphere provided by this is great.
- as pointed out above, the shadows are amazing...things flicker in the candle-light etc...
- Like many other games available on PS3 and X360, the X360's GPU hardware driven FX are very impressive. The reflections, the water/reflections, lighting, etc...These are used alot in Oblivion. While they spent time to redo much of this for the PS3 via software, the X360 slightly edges it out in the area of FX.
- Things look a bit more 3D in the X360 version for whatever reason....when I talk to people and zoom in on their face for example, the wall behind them is clearly at a greater distance...this feeling of depth isnt as prevallant on the PS3 version....
- The darkness on the X360 version actually looks like real black 3d space...for some reason no matter how i adjust the gamma on the PS3 game, it looks like flat space you can see in as well as the moonlit areas in the X360 game. Torches are cool but not a "necessary" on the PS3 edition.
Bottom line - the X360 GPU GFX FX ADD alot to the game / The overworld pop-up kinda sucks, and its nice how its a bit better in the PS3 version...
An odd thing - the status/inventory menu in the PS3 game looks a bit better...it looks like its running at a much higher resoluton or something...the box on the left doesnt take up most of the screen like in the X360 game....I dont get it...
