standing on a yellow square looking at who knows what with mountains all around...and bits of one directally overhead...
I'll pass on trying to understand this one.
uh, leeor, you have it completely opposite there
No actually. 32-Bit programs are very much NOT garanteed to run well on 64-Bit architecture (although 64-bit intel chips are definatly crap). Many programs, especially graphic-intensive programs, will not run any better on a 64Bit CPU and some programs will actually run
slower. It's kind of a 'defy all logic' paradox really. That's why there's a 64-Bit version of Windows. Running 32Bit Windows on a 64Bit CPU will cause it to run more slowly.
It ran at 2 FPS. Will there be quality / visible distance / etc settings to allow the game to run at a more acceptable speed on such old systems?
Most definatly. What you're seeing there is what it would be like on the highest quality setting... well, so far. The highest quality setting would probably also include special ambient effects and whatnot which could be turned off.
Also, the scene is prepared to draw shadows which can have the following settings: Complex, Standard, Off.
Complex shadows are shadows that outline the contours of an objects (e.g., stencil shadows). Standard shadows are just dark splotches on the ground where a unit is. Off is... well... obvious.
However, you're going to need at least a semi-recent machine to run OP3. As Sirbomber noted, if you can't run WCIII (which your setup can't), than you won't be able to run OP3.
