It'll take a lot of memory for game like OFP, that already has to guzzle a large amount of detail for all the crud we put on it. I barely have anything else on my computer (not that it takes a lot of space but it struggles with the crud I forced on it) and it still has problems. Although the OFP should promise great things for us eager fans. Don't get your hopes up, OFP1 may never see detailed rain. :'(
