- They're still optimizing the frame rate, will end up running at constant 30 fps. Sometimes it goes up to 45 fps with all effects on, but they aim at constant 30 fps as already mentioned. Less than 30 fps is considered a bug.
- All textures have been drawn, there are no scanned textures. That's why it looks somewhat cartoony.
- Jetski level has 6 million polygons + water reflection + refraction + bump mapping + jitter + shadows + a good number of characters + physics + AI + volumetric explosions + etc
- It should take 12 hours to complete.
- The AI will learn your behavior and react accordingly. Experienced gamers will have a hard time. They're proud of the AI.
- There are no scripted events when you fight with the AI. You'll never see the same situation twice (to some extent, of course).
- No auto-aim.
- The effects still aren't final. They'll improve close to the very end of the project for optimization's sake.
- There's a lot of stuff we haven't seen yet. It's like a movie where a lot of things happen, and it will have lots of varied action: shooting, fighting, platforming, puzzles, enigmas, races, treasure hunting ("you'll be finding things"), etc.
- Real time HDR lighting: if there's a sunset, everything on screen will have a reddish tone. Everything will be real time.
- 720p allows better geometry. We might not see anything better than Uncharted geometry-wise at 1080p.
- PS3 devkits let them know all the game stats when they're developing it (duh): GPU load, texture memory, level memory, shadow memory, buffers, how is streaming affected, frame rate, etc.
- "I love the AI. The fact that it learns from the player's actions and that it adjusts the difficulty itself is awesomenage. We haven't even exploited half of what the Cell can do. Besides the CPU power, we've got the GPUs (sic) inside the PS3, where you can send some tasks to spare Cell from "digesting" them, so that you get more free CPU time. PS3 still has a lot of untapped power."
- They didn't have the time to include a co-op mode and getting the game finished in November. Tons of ideas left out of it, might make it to Uncharted 2. (This is usual in game development)
- Nathan Drake has 3000 animations.
- Real time cutscenes, no prerendered stuff. It's all real time, in-engine.
