Getting rid of unneccessary bloat (unused programs & data) on your hard drive can help a bit too. Defragging your hard drive may help a little, but there'll probably be only a small gain with that considering the manner that most defraggers work nowadays. File system fragmentation can also play a part, forcing the hard drive to move its heads around more to read all of the fragmented files. Also where this data is stored on the hard drive (physically) can affect the time to access it. Your hard drive will get slower with the more data that you have on it (more info in the directory/file structure to read through to find the data itself). The models (vehicles & infantry) are more complex and some of the maps are bigger (assuming that you're comparing the loading of certain scenarios).Īs redwolf pointed out, hard drive speed may be the biggest factor in the 3D loading process. The textures (comparing un-modded versions) are larger and there are more of them with the later games. It may take longer to load the graphics with CMBB & CMAK (I'm not sure what the speed differences are between CMBB & CMAK).
