It is what I'm saying, and I know it's silly, but I'm anxious. You're right, it's not much evidence at all.
I'm well above the minimum specs, except for the specific graphics chip, the Intel HD 3000 (which uses 512 MB of system RAM, in my case).
For what it's worth these are the options in PC version (from the manual):
VIDEO OPTIONS:
Anti-Aliasing: Turn this on to smooth the graphical edges in the game;
improves quality with more powerful hardware.
Full Screen: This allows you to choose whether to play in full screen mode or
in a window.
V-Sync: Turning this on prevents video tearing by locking the frame rate. (It
is suggested that you leave this on unless you are an advanced user.)
Graphics Profile: Will set the following graphic quality aspects as a group;
Custom allows the user to determine each individually.
Leader Scene Quality: Affects the quality (minimum to high) of the image of
the leader scenes.
Overlay Detail: Affects the quality (low to high) of the overlays.
Shadow Quality: Affects the quality (off to high) of shadows of units,
buildings and other non-terrain items.
Fog of War Quality: Affects the quality (low or high) of the Fog of War.
Terrain Detail Level: Determines the level (minimum to high) of texture detail
of the terrain.
Terrain Tessellation Level: Determines the level (low to high) of mesh detail
of the terrain.
Terrain Shadow Quality: Determines the quality (off to high) of shadows of
terrain.
Water Quality: Determines the quality (low or high) of the water.

the game.
