Well, I bought it last night after posting this message- realised EB games was still open (over priced like all hell)...
Gf4 Ti4200 64MB AGP 4x (was on 30.82, but updated to 41.09 because the game was simply unplayable)
768MB PC133 SDRAM
AMD Athlon XP 2000+
SB Live!
I have to run the game with EAX disabled (there's a patch apparently to fix this, but I haven't downloaded it yet)
I can run with shadows at medium, everything else at high EXCEPT the world textures have to be medium. If I set it to high, the game is simply unplayable... runs fine unless in a fire fight or on the ship in a room with another room underneath it (which you can see because there are only grates for the floor).
If anyone has any idea how to run the game with high detail world textures, I'd like to know! The game ran like absolute toejam out of the box, but luckily someone posted a better configuration for the D3D device driver on the U2 message boards and that significantly improves performance.
The levels are nice, the enemies are damn hard and move quick as toejam when playing on "hard" (I'm on 'Hell' right now, and they actually have aggressive wildlife there)... although the simple 2 kinds of planetary inhabitants is quite obvious. On Sanctuary there was a giant dinasaur looking creature and something that looks like a spacegoat. On Hell there is a trilobite and some kind of pissed off horned creature that keeps chasing me when I get near him. The snow effects on that planet are quite amazing, actually the effects for the entire game are quite amazing... although there is a significant difference between the atmosphere the first UnReal offered and this one. I'm liking it so far, but it can't touch the first UnReal in terms of story line/gameplay/worldly immersion. (and the first UnReal still looks pretty good with all details jacked up)
People who say Half-Life had a good story line/gameplay never played the first UnReal fully patched. That thing had everything, huge levels, took a VERY long time to complete and had all kinds of little details in it. "health" was actually in the form of a plant, you could pick up seeds, carry them around for as long as you wanted, throw them down and they'd grow right in front of you. You kill an enemy, and these gnats/flies would start buzzing around the dead body. UnReal was very well done in terms of atmosphere, and UnReal2 is leaving me a little discontented about that... I had hoped for more atmosphere, but I guess all their devel time went into the more apparent eye candy.
It's obvious that the game was released much like the first UnReal was- unoptimized, poorly setup and improperly prepared for release. After about 4 patches the first UnReal ran flawlessly and was still a blast to play 2 years after it's release (of course, it took about a year to get a system strong enough to run it at full details too).
Hopefully they'll release a patch soon that will greatly improve performance.
