I want to run an old game on my computer. I have Windows Vista 64-bit, I have 4 GB of ram. Now I installed the game on Compatibility Mode and the game starts but I can't see the units while I'm playing. I also noticed that this game shows some of your pcs specs and there I saw that it only detected 112 Mb of RAM, while I actually have 4 GB. Then I modified my boot settings to use only 2 GB of ram and the game started working fine, I saw all the units, etc. Only problem is that I don't know if changing maximum RAM on boot will eventually cause a problem. I would like to know if there's a way of running the game with less RAM (2 GB) since I don't want to be changing the boot settings every time I want to play this game.
