When incremental '.DAT' files are needed to update DATs on a client, the amount of processing needed to decompress, decrypt, combine, and apply them can increase. Although using incremental DATs can help reduce network bandwidth, merging the files on the local computer and applying them consumes more CPU resources during the update. If CPU resources are available,
McScript_inuse.exe consumes the amount needed to complete the update as quickly as possible, and release it on completion of the update. If needed,
McScript_inuse.exe yields the CPU resources to a higher priority process during the update.
This issue is more noticeable on systems with slower processors and less RAM. It also depends on the number of incremental files needed during a given update. It's important to note that minimum system requirements might not allow for optimal performance in all environments.
