The Aces High intro page states the minimum system reqs:
8 MB 3D vid card
PII-233 or better
DirectX 6.1
Now I don't have a machine like that available anymore to try it out.
But I had to upgrade from a P3-500 and with a Riva TNT 32 Mb vid card to overcome extreme low fps in smoke, clouds and high concentration of air or ground activity. Can't imagine that the current game version is still working with a fps of above 20 (20 as an assumption for reasonable game play)
I'm running an AMD Athlon 1 GHz, 256 Mb SDRAM, and a Geforce 2 Ultra (64 Mb) now. Getting a fps of 85 to 50 in most situations.
In the DirectX 8 version running at 50 to 20 fps. When AH will be running at DirectX8 permenantly I probably have to upgrade soon again.
Shouldn't the minimum system reqs be higher by now?
