Well played UT3 demo.
I have only AMD dual core 2.4 if i remember well
GE Force 7600 GT orr GTS ??
2Go Ram and Vista
It runs pretty well on 1024*768.
I can push to 1280*1024 it runs not smooth but not bad : perhaps some 25 FPS i don't know ??
No big slow down at 1024*768 , we can say it runs lots better than any indie engine could do with that good amount of geometry,animations, effects, shaders all at screen in same time

If you play offline and look closely at textures, you will see some good tricks

like detailled textures used with specular and normal map above some diffuses textures.
Integrated lightmaps.
- the base floor on big maps, is simple multitexturing terrain without normal/specular, but the moutain cliffs are meshses with normal/specular.
- the engine uses some pretty glow effects also

- in 1024*768 ,textures at high : weapons looks incredibly detailled,
but the engine i'm sure uses LOD very well on vehivules, characters indeed.
I just can say in fact it's not incredible :
it's only Normal shader/specular/glow and scene Bloom/Hdr very weel used.
after that the engine have pretty optimisations, like i'm sure their evolved
BSP system combined with terrain.
But the BIG thing is the game is TOP NOTCH 3D ART.
nothing else , the levels blow you out , caus they are incredibly beautifull.
Some vehicules, outdoor buildings are INCREDIBLE 3D ART, that normal/specular shaders just bring up

I don't think we even see in indie domain just one vehicule/building as good as their ones

I'm a bit disappointed about characters, detailled,texture also, but the game runs too fats to see anything.
Yeah the characters are not incredible at all in game (the demo), perhaps better in complete game ??
Well just can say , powerfull/fast Next Gen engine,using shaders that indie
engines uses.
But UT3 is lot of tools , optimisations, easy Classes code,physics you won't
have together in indie domain

Again GREAT 3D ART MASTERPIECE on levels and vehicules,weapons

(but too fast game , far from some BattelField 2 strategy, but can be very very fun)
Just try it
