So, I've started doing the map for my WWI scenarios. I'm going to do them all at the same scale (20km/hex) so I'm creating one large map that stretches from Switzerland in the west, to the Black Sea in the east. Riga in the north, to Salonika in the south. That way I can just chop off the parts that aren't needed for any given scenario.
I'm coming up with 95 hexes N-S and 106 hexes E-W. 106 is too large for OPART.exe. What I want to know is, how many people have problems playing in OPART300? The last time I designed a scenario, 3 or more years ago, OPART300 taxed a lot of people's machines too much and they couldn't play them without 1-hour waits for supply calculations and such. I know to a certain extent the size of the scenario still matters in OPART300, but even regular OPART scenarios opened in OPART300 seemed back then to run significantly slower (reserved memory issue perhaps?).
So, how many people here find OPART300 too much for their computers?
